New Era of Computing – “Internet of Things”

“Internet of Things” means network of sensors where data is exchanged, using different connectivity protocols, with systems.

define the Internet of Things as simply an interaction between the physical and digital worlds. The digital world interacts with the physical world using a large amount of sensors and actuators.

Sensors and actuators are devices, which help in interacting with the physical environment. The data collected by the sensors has to be stored and processed intelligently in order to derive useful conclusion from it. Note that we broadly define the term sensor; a mobile phone or even a microwave oven can count as a sensor as long as it provides inputs about its current state . An actuator is a device that is used to effect a change in the environment such as the temperature controller of an air conditioner.

Some examples you can relate it

1.Smart Homes:- The smart home is likely the most popular IoT application at the moment because it is the one that is most affordable and readily available to consumers. From the Amazon Echo to the Nest Thermostat, there are hundreds of products on the market that users can control with their voices to make their lives more connected than ever.

2. Connected Cars:- These vehicles are equipped with Internet access and can share that access with others, just like connecting to a wireless network in a home or office. More vehicles are starting to comeequipped with this functionality, so prepare to see more apps included in future cars.

Advantages:

1.Cost Savings:- IoT fundamentally proves to be very helpful to people in their daily routines by making the appliances communicate to each other in an effective manner thereby saving and conserving energy and cost. Allowing the data to be communicated and shared between devices and then translating it into our required way, it makes our systems efficient.

2.Communications:- IoT encourages the communication between devices, also famously known as Machine-to-Machine (M2M) communication. Because of this, the physical devices are able to stay

connected and hence the total transparency is available with lesser inefficiencies and greater quality.

3.Automation and Control:- Due to physical objects getting connected and controlled digitally and centrally with wireless infrastructure, there is a large amount of automation and control in the workings. Without human intervention, the machines are able to communicate with each other leading to faster and timely output.

4.Network:- IoT network benefits not one but all i.e. individuals, society,

stake holders of businesses etc. due to the fact that IoT network saves

time and money. IoT systems delivers faster and accurately with

minimum utilisation of energy. This improves quality of life.

Disadvantages:

1.Complexity: There are several opportunities for failure with complex systems.

For example, both you and your spouse may receive messages that the milk is over and both of you may end up buying the same. That leaves you with double the quantity required. Or there is a software bug causing the printer to order ink multiple times when it requires a single cartridge.

2.Safety: There is a chance that the software can be hacked and your personal information misused. The possibilities are endless. Your prescription being changed or your account details being hacked

could put you at risk. Hence, all the safety risks become the consumer’s responsibility.

How to implement applications using IOT:

Using iBeacon:

Now you can developing for Bluetooth Low Energy (BLE) devices on iOS using the Core Bluetooth framework, let’s turn our attention to iBeacons. Working with iBeacons is not that bad. It might feel a little unfamiliar because you’re working with a physical device outside the territory of your iOS Device. Actually pretty straightforward to developed applications with following sixes steps:

1.Create a CLLocationManager.

2.Authorize Core Location.

3.Create a CLBeaconRegion.

4.Start Ranging or Monitoring.

5.Catch any beacons that are detected and use them as needed.

6.Stop ranging the Beacon Region.

All the news was now about Arduino, Raspberry Pi, and making. Riding alongside these technologies were the Bluetooth Low Energy prototyping devices like iBeacons.

iBeacons are Bluetooth Low Energy devices, but their purpose is fairly straightforward. In briefly main points all they do is broadcast a set of numbers and a single strength measurement that lets your app determine how far away the device is.

As we know parts of the Zero-to-BLE series, Bluetooth Low Energy devices like to use UUIDs for identification, and iBeacons are no exception. When you purchase and configure an iBeacon, it will be identified by three pieces of data: the UUID, and then two other numbers which are just 16-bit unsigned integers that you can use for identification or categorisation purposes to group related devices that have the same proximity UUID. Those two integers are referred to as the major and minor values.

Here’s what’s interesting about the way this works: all of your

devices can share the same UUID, and then you can use the major and

minor values for the breaking up of the devices into smaller groups and

then into individual devices.

Using EddyStones:

The Eddystone library is built on top of the Cordova BLE plugin. The Eddystone plugin packages the BLE plugin and the required JavaScript libraries into one package for convenience.

Eddystone is an open, scalable BLE beacon format that allows developers to create contextually aware experiences on both Android and iOS devices. Eddystone devices have the ability to do many things at the same time. This is possible because Eddystone supports multiple types of broadcast signals, or in BLE terms, “frames”. Eddystone’s multi-frame support is major differentiator between the Eddystone and Apple’s single-frame iBeacon. Summary Eddystone frames:

1.Eddystone - URL (Physical Web) – This frame broadcasts URLs, allowing BLE devices to emit URL links to about location specific content.

2.Eddystone-UID – Broadcasts specific unique identifiers which native applications listen for to trigger context-aware notifications and deliver proximity-aware user experiences.

3.Eddystone-TLM – Broadcast telemetry information such as battery information, temperature, and many more.

Conclusions

Here, we can conclude that implementing IOT in mobile application makes developer build application out of the territory of physical device and simplifies the data tracking and monitoring of information. Connect world with digital applications to enhance real world problem.
