4 essentials before you implement Online Radiation Monitoring System (ORMS)

The Internet of Things (IoT) is the network of physical objects, devices, vehicles, buildings and other items which are embedded with electronics, software, sensors, and network connectivity, which enables these objects to collect and exchange data which is called Machine-to-Machine (M2M) communication.Online Radiation Monitoring SystemORMS is an IoT application which collects the data from the sensor nodes and publishes it to cloud. All the analytic work will take place on Cloud. ORMS will be installed in an Edge node running on Linux OS and has serial port, USB port, Ethernet port or a WiFi to connect and communicate with the sensor nodes.Development environment setupORMS is developed by using Kura/OSGi. OSGi is a java based framework which has small modules called bundles which run in light weight container. Kura is a Java/OSGi-based framework for IoT gateways. Kura APIs offer access to the underlying hardware (serial ports, GPS, watchdog, GPIOs, I2C, etc.), management of network configurations, communication with M2M/IoT Integration Platforms, and gateway management.ImplementationORMS contains one main application OSGi bundle and four communication OSGI bundles called weather sensor communication bundle, GM tube communication bundle, Anti tamper communication bundle and MCA communication bundle. Main application bundle is the main bundle that depends on other communication bundles that will organize the collected data from sensor devices and publish it to cloud as a whole.ORMS ConfigurationsMain bundle has configurations like longitude and latitude value of the device, how frequently data should be fetched from sensor devices, port name and data_bit of the devices to connect etc. Data fetch from devices and publish to Everyware cloud with configured time interval set by the user from Kura/ESF web UI.Cloud space for all devicesWhile fetching data from sensor device if error/failure occurs in sensor device, Main application will immediately publish corresponding alarm to Everyware Cloud. For example when Anti tamper screw is opened or tampered. User can login to Everyware cloud and monitor or manipulate with result data.

The 6 Most Important Building Blocks of the Internet of Things

Today’s private and public organisations are all about innovating faster. And this faster innovation is one of the most important driving factor of internet of things. The increase in globalisation and the constant effort to seek better customer experiences are also driving the IoT business today. There are building blocks of IoT that transform devices into connected, intelligent data sources. They are: Sensors on all devices: These sensors are used to measure all kinds of information about a particular device. As devices become pervasive, these sensors are going to make all data about them available to the network. The embedded devices that form the building blocks of IoT are accessed over a network that has protocols to allow information exchange. The sensors in place use RFID protocols to distinguish between the devices in the network. These protocols also make the devices addressable and measurable. Network connectivity: The data gathered by the embedded devices have to be transmitted to remote devices over a network. The destination of these network communications can be either your smartphone or a cloud-based application. The communication networks use wireless communication protocols primarily, along with PAN/BAN/LAN communication links. Routing gateways: IoT gateways are used to translate, disseminate, and route data to the cloud by use of a wide area network (WAN) communication technology. Since the devices part of IoT come in all sizes and shapes, there is a wide variety of input types to be considered in this. The gateway designs can make use of diverse types of components to take care of these inputs. Microprocessors: Embedded systems are called that for a reason. They have a microprocessor embedded, making them capable of processing data and being programmed. The microprocessors are quite similar to the ones you have in your smartphones and tablets. These microprocessor components are essentially programmed to communicate properly with the cloud or a wireless network to properly engage with the remote device. Software part: The interconnection of these components along with proper software administration is essential to make IoT a reality. The software part can include middle-ware, firmware, and application software. Security: Last, but not the least, with the advent of so many connected devices, security becomes a major challenge in IoT. Foolproof security systems will have to be in place to compete against attacks on such myriad devices being connected. It’s very easy to understand how essential this is. The Internet of Things brings with it a huge opportunity for all business sectors. Aziro (formerly MSys Technologies) is deeply involved in the development of IoT applications for various clients.

What are the Challenges of Testing IoT Applications?

What is Internet of Things (IoT)?The internet of things (IoT) is a computing concept that describes the idea of everyday physical objects being connected to the internet and being able to identify themselves to other devices. The term is closely identified with RFID as the method of communication, although it also may include other sensor technologies, wireless technologies or QR codes.The IoT is significant because an object that can represent itself digitally becomes something greater than the object by itself. No longer does the object relate just to its user, but is now connected to surrounding objects and database data. When many objects act in unison, they are known as having “ambient intelligence.IoT ExamplesSome examples of day to day real life implementation are as follows:1) In Wearable technologies:Wearable gadgets such as MI bands and Apple watches synchronize easily with the mobile devices.2) Infrastructure and development:With the use of an application such as Telensa, it is easier to get the real time outdoor lighting data and based on these, the street lights are switched on or off. There are also various applications so as to control traffic signals and parking availability in a sophisticated city layout.Technology used in IoTFollowing are the few of the most used technologies in IoT:WiFi:This is the most commonly used choice for IoT. When on a LAN, this helps in transferring files, data and messages seamlessly.Bluetooth:This is used where short range communications are enough to get away with the problem. This is mostly used in wearable technologies.Z-Wave:is a wireless communications protocol used primarily for home automation. It is oriented to the residential control and automation marketNFC[Near Field Communication] is used to enable two-way interactions between the electronic devices. This is basically for the smartphones and is mostly used to do the contactless payment transactions.RFID[Radio Frequency Code] tags and EPC [Electronic Product Code]QA Opportunities in IoT TestingNFC Payments: NFC (near field communication) is the technology that allows two devices—like your phone and a payments terminal—to talk to each other when they’re close together. NFC is the technology that enables contact-less paymentsApple Pay/Samsung Pay: Apple Pay empowers users to make use of multiple credit/debit cards to make pay via Apple devices. ‘Samsung Pay’ is linked with major banks which includes JP Morgan and BOA.Telematics: It also helps to keep an eye on the driver behavior for car insurance done by insurance firms.Payments through wearable devices: Payments can also be done through google glass or a wearable device.Challenges of Testing an IoT ApplicationInternet of Things (IoT) and technologies related to it confronted testing terms with many challenges As the IoT devices seamlessly connect and communicate with a wide variety of platforms, devices and operating systems, the main challenge the testing team faces is HUGE. However, such challenges are completely be heavier when it comes to the security challenges imposed by the software architecture of the IoT application. With innumerable devices connected to each other in the IoT, there are numerous potential attacks that can be exploited by the cyber criminals. If cyber criminals were to tamper with the settings of such devices, the consequences could be highly devastating.With the amount of detail that needs to be covered in an IoT testing, having a list of critical QA priorities is very important. Such priorities need to cover the length and breadth of the challenges of IoT testing.The different areas of testing an IoT application are as follows:Functionality: Web/UI, embedded and back-end computing.– Compatibility: Multiple OS flavors support, Protocol and product Versions, Backward Compatibility and Mobile OS.– Connectivity: Communication between the devices, third party applications and the infrastructure.– Performance of the network, communication and internal computation.– Exploratory: Rare scenarios and beyond functional requirements and structured testing.– Security: Privacy, Autonomy and Control.The top challenges and solutions that the QA can enlist are as follows:– The convergence of Hardware and Software: The ecosystem of IoT is made of devices, sensors and applications. When it comes to millions of sensors and devices in conjunction with intelligent software, only functionality validation is not enough.– Additional factors along with a working system: IoT works with sensors and devices communicating with multiple software back-ends with complex algorithms.It is not only enough to ensure a working set of device software. It requires a robust validation process with extremely complex real time scenarios. Obtaining such scenarios is an extreme challenge for the QA team.– Sensor Interactions: The biggest challenge lies in the creation of an environment in order to test the real-time implementation of the IoT application. Setting up such an environment requires numerous analytics engine and a significant experience in technical simulation. Although the hardware and the protocols are well tested beforehand, understanding the application intelligence and the device complexity is an extremely big challenge for the QA experts.– The device interaction layer: Here the software and hardware components interact in a real-time IoT environment. Their conformance to standards, interoperability, backward compatibility and security are the additional challenges in addition to typical software testing.– The user interaction layer: The success of the overall application depends on the user receiving a seamless experience. The main testing challenges include the simulation of network modes along with device level validation, the real time usability along with the back-end IoT environment.Challenges of Testing an IoT ApplicationThe IoT has been around for a years, but is rapidly developing market. Looking at the current trend in next coming years the things are definitely going to change. If you look at the number of devices and software in IoT, then the count is growing rapidly every day by day. As a result there will be more testing and testers are required to find the bugs in the IoT software and release more quality software to end users.Happy Testing!!!

Internet of Things (IoT) – Mirage to Reality!

IoT is nothing but a connection of electronics, people and software and anything & everything that can collect and transmit data to create logical reasoning and decisions. This includes anything with an on and off switch, such as your thermostat, light switches or water meter. It is a relationship between machine to machine (M2M) and between machines and humans. In a recent research report Gartner predicts that there will be more than 26 billion connected devices by 2020. We are heading for a future that states whatever can be connected will surely be connected! It’s given! It is said that by 2025, the potential economic impact of IoT will be around $3.9 to $11.1 trillion per year. As sensors are getting cheaper, almost all objects can be a part of the network. This phenomena is changing the general manner of living. The IoT industry will be a booming market as the sensors and modules will sum up to 50% or more of spending by the world. Sales and device installations will generate the economic value owing to savings that will be realized by having this technology in place. Maintenance – What’s that? By integrating the IoT in a company, the effort and cost of maintenance of systems and processes will be reduced to nominal or zilch. How? Well, predictive maintenance is the answer to the unsolved mystery. With the technology and logics applied, spotting and a fault or error and fixing it immediately is a matter of regular automated chore and will facilitate the smooth and disaster free functioning of assets and systems. IoT will play an important role in improving the productivity and efficiency in maintaining and reducing costs drastically. It will be instrumental in generating real time data analysis, adopt predictive maintenance and in time provide recommended repair actions. Fuel the reality.. IoT also has the power and intelligence to monitor and predict energy consumptions and remedies by at least 10 to 15 percent. It is a time, labor and cost saving technology that wouldn’t get stranded. The magnitude and horizon of work gets larger and tasks can be accomplished in much lesser time. Clubbed with Designing and Developing Software on Gateways, enterprise asset management (EAM)/computerized maintenance management system (CMMS), the IoT can enable a team capture data, quickly and analyze emerging trends related to your domains and assets and aggregate other information based on new and accurate datasets. Companies should be ready to adopt and implement this technology to shift onto a brand new era of innovation and efficiency.

Internet of Things: What the Future Has in Store!

Imagine your washing machine calling on your smartphone and telling you in a Siri-like voice that it’s time to wash your socks. Imagine you receiving texts on your phone about your garage door being left open, your car out of fuel, or your toaster finishing its work. In the near future, this may no longer be science fiction; it is very much possible that any object you have in your home will start talking to you–in fact, not only to you but to any other objects around. What enables this is a technology known as Internet of Things (IoT).What is this revolutionary new technology? What is Internet of Things? This term has existed and been hackneyed since the early ’90s so as to breach the boarders of cliché. People have come forward with certain other terms to substitute “Internet of Things,” but most of them turned out to be just bush-league. Internet of Things refers to a future in which your commonplace objects—things that you normally do not associate with technology—start to communicate as part of a network. This concept radically augments our idea of the smart planet, because you can communicate to not just computers but every object in your home over the Internet.IoT and the Fascinating FutureIf you are a fan of popular sitcom Big Bang Theory, it has an interesting episode in which the characters light lamps and turn down stereos using their laptops by sending signals across the Internet. After a while, by giving open access, unknown people start playing around with the lamps in their apartment. This kind of development is highly invigorating as well as slightly intimidating for many people.While on one side people are talking about the advantages of IoT, a discussion is looming large on the horizon about the security concerns surrounding the concept. For instance, what if the bad guys hack into your smartphone to disable your home’s security system and open the doors of your house while you are away in Hawaii on a vacation?One area IoT is going to transmogrify is the automotive industry. Already, the cars are as smart as you want them to be. A few days ago, I was watching the Audi keynote in the International CES (watch it below), and wow! The cars can not only park themselves but drive you through busy streets. The technology is that sophisticated now. Last week, Fox News published a piece on V2V (Vehicle to Vehicle) communication system that helps cars communicate with other cars in the vicinity to convey important information, such as whether or not the driver is applying breaks properly to avoid a possible collision.The US department of transportation is considering a regulatory proposal for vehicle to vehicle communication. You can go to BBC Top Gear and be literally flabbergasted at the automotive technology that is emerging. In essence, cars have advanced through technology in the last decade more than they ever did in a century led by mechanical engineering. Embedded computing technology is at the helm of all these developments.When IoT comes to our world, these cars will be well connected, through 4G technology. They will communicate fluently to bring assistance to you wherever you are.Cisco has done quite a bit of research on Internet of Things (which they call Internet of Everything in their vernacular). Check out that site; it’s a goldmine of information on IoT. According to Cisco’s findings, released in Feb 2013, IoT globally will be worth 14.4 trillion dollars in the next decade. I happened to look at the data concerning our country too, and the value at stake seems to hover around 35 billion USD. When it comes to the zenith of information technology, the United States, the total value at stake seems to be 473 billion dollars.IoT: How It Changes Your World?I have given you a slight idea of how IoT is going to change your future in the beginning of the article. While some of the ideas may be a bit out there, there is virtually no bounds to the way applications can be developed to incorporate things. Embedded systems will be subsumed into almost every object to make it more intelligent. That’s where the washing machine that talks and texts comes in. These developments can significantly improve your lifestyle.Just as the lot of geeks in the Big Bang Theory, IoT will exhilarate the techies amongst us. They will come up with specialized applications that do everything from garage-door-opening to toilet-seat-lifting. The way IoT can uplift the services in certain industries today is bound only by your imagination. Surveillance, security, healthcare, education, retail, etc., are some of the industries that will taste the massive benefits of Internet of Things.There is a minor problem. And that concerns software development. For an analogy, consider today’s mobile app development. While a developer needs to concentrate on only one device (or two) in case of iOS development, he has to consider a plethora of hardware configurations, resolutions, processors, and OS versions when it comes to Android. Imagine if a developer needs to create an app that controls refrigerators or washing machines? There is more diversity there than the number of verses in the King James Bible, figuratively speaking.This development intricacy has also been discussed by a recent podcast in GigaOM. They also discuss the rampant privacy concerns surrounding the subject. Play the podcast to listen:How IoT redefines our world is well illustrated in this image:As a first step of inventorying everything to be managed better, you can use technologies such as RFID (Radio-frequency ID) and NFC to tag each object. Then, they can be managed through a network, and locating and securing the inventoried objects become a piece of cake.There is, however, one little issue concerning IoT: the standardization. We should come up with a way to standardize the tagging technologies that we use—RFID, NFC, barcodes, or QR codes. It should not be as wayward as in the case of 4K resolutions (wherein there are six different resolutions and no fixed standard).In essence, for coherence and congruence, everything from development to nomenclature should follow a standard.How far are we in realizing IoT in our cities? Well, when it comes to Ubiquitous Cities (aka smart city, wherein everything is connected with computers), Songdo IBD of South Korea is probably the first. It is a smart city where everything is connected, not just computers.ConclusionI could go rambling on and on about IoT as it is quite an interesting topic. Aziro (formerly MSys Technologies)’s development teams have expertise in embedded computing technologies, which is right there at the brink of IoT. It is inspiring to know that we are part of a global team working toward the future of technology.

How to build a smart home using Raspberry Pi device

AbstractThis article describes a case study on building a smart home using Raspberry Pi device. We have used AndroidThings as the OS on the Raspberry device, and Firebase as backend service for storing the data (which is synced real time with all devices authenticated). The article gives a brief description on the current trend on Internet of Things (IoT) devices (popular IoT platforms like Raspberry Pi, Arduino, etc.). In addition, the article mentions a brief on AndroidThings OS (provided by Google), which was developed for IoT devices and support Java framework for application developers to develop IoT applications using Java. We also talk about Firebase, which was used as a backend to store data.Possibilities of controlling several devices from a single panel in Aziro (formerly MSys Technologies) office. (Creative visualization)AndroidThingsAndroidThings brings the entire Android platform now to devices on which you can build Java based IoT applications. It has the potential to change the game for IoT, like Android did for devices.The thing that we have found most IoT developers struggle with, is collecting sensor data, transport and save that data to the backend. And the real value lies in analyzing that data for alerts, visualization, etc. And that is where we believe we will see a lot of people understand the values of Firebase, Google Cloud Services more. AndroidThings, developed by Google fits all these pieces together to create a compelling IoT platform.One of the interesting things that is being mentioned as a strength of Android Things is that OS updates will be distributed by Google themselves.FirebaseFirebase provides a quick way to persist sensory data collected at the device level, and it works great with the Android APIs, which is supported by AndroidThings. A lot of mobile and device programmers that I have come across struggle with server side programming. Firebase can really help bridge that gap and make it easier.It will be interesting to see developers use its offline features. If you are new to IoT or in general any device that collects data and needs to transmit it over networks, the golden rule to be assumed is that network connectivity cannot be assumed. As a result, you will need to collect the data offline and when network is available, transmit this over to your server. Firebase with its offline feature can really make this simple for a lot of developers.Firebase has a ton of features including Real-time Database, Authentication, Cloud Messaging, Storage, Hosting, Test Lab and Analytics but I’m only going to use Authentication, Real-time Database.AuthenticationAny proper app has some form of security. Firebase Authentication provides this form of security by flawlessly providing an OAuth platform that integrates popular OAuth providers such as Facebook, Google+ and Twitter.Real-time DatabaseThis is a NoSQL cloud database. Okay, this means that all data in your application is stored online in the cloud and an added advantage is that it syncs across all connected clients in real time (as it changes).Implementation: Smart Home using RaspberryPi.This implementation requires the following:Software:1.Java.2.Android Application Development.Hardware:1.RaspberryPi 32.Ethernet Cable3.LED Bulb4.1KΩ resistor5.Female to Male jumper wires6.Breadboard7.Power Supply for Raspberry Pi8.SD Card (8GB or higher)Demo: LED bulb controlled through internet (using Android device) Software implementation1.Android Client app – talks to firebase, updates value in firebase.2.Android Things App – reads value from firebase and sends instructions to the Led bulb (through Raspberry Pi device)WorkflowAny Internet enabled android mobile that has android app, connects with Firebase using OAuth authentication.After successful authentication, it updates/reads value from Firebase.Firebase updates the values to IoT device that has AndroidThings OS and Android IoT app.IoT device controls all the connected electronic devices.Connecting IoT device in Cloud.Connecting IoT device in Cloud.1.

We have great potential in IoT. This was just a simple demonstration for IoT. From security systems to healthcare; from transport companies to warehouse management, the possibilities in IoT are simply endless. Further, with the advent of mobile apps like IFTTT, communication has gone to the next level. We can confidently say that the future does belong to IoT.References:https://developer.android.com/things/index.htmlhttps://developer.android.com/things/hardware/raspberrypi.htmlhttp://fritzing.org/ (Electrical layout diagram tool)https://www.aziro.com/internet-of-things/https://github.com/amitshekhariitbhu/awesome-android-things

How to Design an Android Wearable using Smart Bluetooth?

We are living in a day and age, where technological innovations drive our daily life. Wearable technology has been talked for long, but in recent past we have come to see live products that help in our daily lives. Within the Android ecosystem, wearable technologies have a tremendous scope for growth, given the nature of open ecosystem surrounding it. In this article, we will present how Aziro (formerly MSys Technologies) Android team helped Spree Sports, a leading fitness monitor wearable device come out to market with a feature rich and pleasing UI android application.The ability to track performance and the body’s reactions to training or workouts is very important to fitness enthusiasts.Bluetooth has been around since the mid-to-late 1990s and has become the standard for peer-to-peer networking of devices over short distances. One disadvantage is that it can draw a bit of power, and this becomes something of an issue on mobile devices, and even more so on wearable technology where the batteries need to be smaller still. Also two Bluetooth devices must be paired before they can communicate with each other. The pairing process needs to be performed only once but can be an unpleasant experience for the userHow Aziro (formerly MSys Technologies) designed and implemented their Android mobile applicationThe Spree Sports headband is a far-reaching fitness monitor that takes your fitness to a whole new level. Spree is worn around your head in order to give the most precise reading of body temperature, heart rate and movement using biosensors.Spree takes “step counting” to a new level by tracking exact distance and speed travelled with the mileage tracker. Spree can accurately measure your heart rate in a non-invasive and comfortable way.We at Aziro (formerly MSys Technologies) understood the client’s requirement and came up with the below UI. We independently implemented the complete functionality, including interfacing wit.The key to using the Spree Sports headband is the Spree smart performance mobile app. While you exercise, the Spree fitness monitor tracks your body temperature, heart rate, distance, speed, time and calories burned. This biometric information simultaneously streams to your mobile app using Bluetooth smart technology. Since you can view an analysis of your progress in real time, your fitness goals become more clear and tangible.One can observe calories burned during your workout with the calorie indicator, and track distance traveled or set target heart rate. You can even listen to your music library while using the app. This all-around smart performance app helps elevate your fitness training.Bluetooth Low Energy, or Bluetooth LE for short, or BLE for even shorter still, was introduced as part of the Bluetooth 4.0 (sometimes called Bluetooth Smart) specification, and addresses these specific issues. As far as improved battery life is concerned, many manufacturers are claiming months or even years for some sensors. Google added BLE support to Android 4.3 (API 18).Challenges Faced during development:The first major challenge is in the BLE pairing process. For traditional Bluetooth development, the task of pairing two devices was largely the responsibility of the user, but with BLE that responsibility lies much more with the developer. That is a good thing because it makes the whole pairing process much more straightforward from our users’ perspective.The other major difference is the actual communication itself. In traditional Bluetooth development there were a number of options. Fundamentally these were based on a socket architecture very similar to standard network sockets. Essentially our data is streamed over sockets, and it is a case of both devices knowing the format of that stream. BLE takes a different approach, and centers around attributes. An attribute is essentially an atomic piece of data (i.e. an integer or string) which is shared between both devices. Attributes may be used to either represent data or control how the sensor behaves. For example, in a heart rate monitor one attribute may hold the current heart rate value (data) and another may contain a setting for how often the heart rate value should be updated (behavior).Finding BLE Devices:To find BLE devices, you use the startLeScan() method. This method takes a BluetoothAdapter.LeScanCallback as a parameter. You must implement this callback, because that is how scan results are returned. Because scanning is battery-intensive, you should observe the following guidelines:As soon as you find the desired device, stop scanning.Never scan on a loop, and set a time limit on your scan. A device that was previously available may have moved out of range, and continuing to scan drains the battery./** * Activity for scanning and displaying available BLE devices. */ public class DeviceScanActivity extends ListActivity { private BluetoothAdapter mBluetoothAdapter; private boolean mScanning; private Handler mHandler; // Stops scanning after 10 seconds. private static final long SCAN_PERIOD = 10000; ... private void scanLeDevice(final boolean enable) { if (enable) { // Stops scanning after a pre-defined scan period. mHandler.postDelayed(new Runnable() { @Override public void run() { mScanning = false; mBluetoothAdapter.stopLeScan(mLeScanCallback); } }, SCAN_PERIOD); mScanning = true; mBluetoothAdapter.startLeScan(mLeScanCallback); } else { mScanning = false; mBluetoothAdapter.stopLeScan(mLeScanCallback); } ... } ... } Conclusion:By combining a developer’s imagination with Bluetooth Smart technology, the future of wearable Bluetooth technology is virtually unlimited. Bluetooth Smart creates a playground for companies willing to experiment with creative wearable solutions. Bluetooth technology is energy efficient, low in cost, offers high security and easy to work with, and it takes into account sustainability concerns for reducing the carbon footprint.

Top 3 Data management Challenges for Internet of Things

The Internet of Things is slated to be a 19 trillion dollar market by 2020 according to a research conducted by Cisco Systems. Internet of things (IoT) is a technology that brings the world’s devices together to form a single network of constant communication. It can drive growth as well as provide great lifestyle improvements tomorrow. Today, the data traveling through the networks is increasing on a daily basis. The volume of information is unfathomably deep and varied. Also, the kind of growth that these data systems see is nothing short of exponential. The big challenge posed by big data is quite hard and mind-numbing for many organizations. In a study by the International Data Corporation, it seems only one percent of the entire data in the world is actually being processed by enterprise data crunchers. On the other hand, big data also provides many business-level benefits to organizations. This can provide business insights which are otherwise hard or impossible to obtain. With the advent of IoT, the data generated in the world will increase even more. In a survey, when asked about the key area that will make a difference in IoT-related solutions, the largest number of respondents replied “data.” While connecting things can be quite a difficult first phase of IoT, it’s the processing of the huge volume of data that these things bring that most people see as the most arduous task. Key challenges identified by industry experts include: 1. Integration of data generated by multiple sources Extensive use of smart devices and the easy and free accessibility of cloud has given rise to a new user culture. Users are unabashedly using online technologies, apps and devices that are interconnected for seamless transitions from device to device. The immense data thus generated has given rise to a unique challenge to organizations- that of data collection. Companies have to consider factors like handling the different types of data, the sources where they originate from, installing physical data collecting devices, best methods to gather data, etc. Besides collection of new data, the preexistent data within the organization also needs to be upgrade for analyzing. This indicates how difficult it is to integrate data from multiple IoT sources —especially the ones when sources are wide-ranging. This kind of data cannot be copied to any central node as it is not physically, or financially viable, thus forcing organizations to look for alternative tools which can collate and analyze the big data as one logical database instead of a mass of unrelated data. Such tools will be particularly valuable for IoT applications that depend on data from many distributed sources, such as embedded sensors, video cameras, and third-party data sources. Integrating data from multiple sources is hard. Besides tools, it takes immense planning and fore-thought to get the most accurate results. But, the results of a good integration project are worth the time invested. Data integration projects, managed properly, can give you the data you need to make decisions. 2. Automation of the data collection process After IoT data is captured and integrated, organizations face the challenge of getting the data to the right place at the right time so it can be analyzed. This includes assessing the data to determine whether it needs to be moved or analyzed where it is- at the user end (on the device) or wherever the data is transmitted for offsite storage and processing. In certain cases it is important that the data at the user end needs to be processed right there and then, whereas certain cases demand that data be transmitted to the data center or the cloud for a detailed analysis. Organizations need to take a call and decide how to analyze the data. Some factors that you need to consider before you automate IoT data are: Performance requirements of the IoT application: Are there requirements for low latency that will impact where the data should be processed? There are certain IoT use cases where low latency may be a requirement. Data preprocessing opportunities: In several instances, it will not be appropriate to transfer all the data generated by an IoT solution to the cloud for processing. It may make sense to process or compress IoT data before transmitting it to the cloud, or to transmit only select data. Highly distributed IoT applications: This includes some IoT applications that involve a high level of data distribution making it imperative to process data near the user end. Critical data produced in large volumes would a need an extremely good data speed in order to transfer, analyze and then transfer back the data. With some domains generating data in volumes of 1-2 TB per day, this process may take longer than needed, thus defying the need for real time analysis. Such instances need that the IoT data be analysed as close to the user end as possible to avoid any time discrepancy. According to a survey, respondents believe that within the next three years, “most” of the data produced by their IoT solutions will be processed near where it is generated — using intelligent devices and appliances. 3. Analysis of the data to gather actionable insights IoT data must be analyzed to identify actionable insights that can be used for better user engagement. Data that is not analyzed and optimized is not beneficial to anyone. Organizations often lack analytical capabilities due to a lack of tools and resources that deal with the expanding size, speed, variety, and distribution of data. The solution often requires the ability to receive detailed, real-time information. Conclusion The perfect realization of IoT’s ends can be achieved by fulfilling of all three of these tasks. Insights driven by data analytics will create opportunities for process changes and optimization. The insights in many ways will foster transformative rather than incremental changes in business and operational processes. According to one survey, IoT has the potential to automate close to half of the existing manual processes in many organizations. IoT definitely provides a humongous array of opportunities to today’s enterprises. It’s the holy grail of process improvement as seen by many companies today. One thing, however, is that IoT will make it extremely difficult for organizations to align its business processes for the effective use of the technology. Hence, strategic planning of IoT solutions and methodologies can be quite a large industry in the coming days. Are IoT and Big Data baffling you and your business?
