WTF IoT is?

“Internet of Things” the next big to land on the technical market. Well it’s a dynamic global infrastructure with self configuring capabilities where physical and virtual “things” are assigned an identity, physical attributes and use intelligent interfaces , seamlessly integrated into theinformation network.

Briefing out its basically a network of physical objects or things embedded with electronics , software , sensors and connectivity to enable objects to exchange data with the Manufacturer, operator and other connected devices. As the devices connect with each other they become an intelligent system of systems that allows objects to be sensed and controlled remotely across existing network infrastructure creating opportunities for more direct integration between the physical world and computer based systems, resulting in improved efficiency, accuracy and economic benefit.

Now why care about IoT?

Estimations say there will be nearly 26 million devices on the Internet of Things by 2020. We are always connected , we have access to virtually unlimited amount of information, we have access to cloud, to apps, and When this intelligent system of systems share data over the cloud they can transform our business, our lives and our world in countless ways. When we start making things intelligent , it’s going to be a major engine for creating new products and new services.

We are talking about the world blanketed with billions of sensors that take information from real physical objects and uploading it to the internet. It’s a world where your environment transforms as you walk through it, because technology that you may not even be aware of is monitoring your every move through these sensors.

Just imagine how would it be when your living room identifies your presence and taps into a cloud based profile of preferences like temperature control, lighting ,music, decor and so on.

How if the sensors detect your stress levels and apparently change the music that’s playing in your room or the sensors outside knows it was snowing earlier , so the climate control begins to crank up the heat in anticipation as you walk through the door

Understanding the stuff:

Yeah!! Ofcourse on the other side of the coin the question arises as for how many objects could be connected over the internet. Well the answer resides in IPv6 .

IPv6: The latest version of internet protocol IPV6 creates more potential address than there are atoms on the surface of the earth. It provides an identification and location system for computers on networks and routes traffic across the Internet . Now every device must have an IP address to communicate with other devices. Here IPv6 serves the purpose . it uses a 128 – bit address, allowing 2128, or approximately 3.4 x 1038 addresses.

A few more key components building the architecture of IoT are UDP(User Datagram Protocol): With UDP computer applications can send messages referred to as datagrams, to other hosts on an Internet Protocol network without prior communications to set up special transmission channels or data paths TCP(Transmission Control Protocol): It’s a highly feasible host-to-host protocol between hosts in packet – switched computer communication networks and in interconnected system of such networks.

6LoWPAN: Its basically an acronym of IPv6 over Low Power Wireless Personal Area Networks .

IoT-Graphic

However its encapsulation and header compression mechanisms allow IPv6 packets to be sent to and received from over IEEE based networks.

Well IoT depends on softwares like Riot OS and Thingsquare Mist. Anyways briefing them out, Riot OS is predominantly an operating system for IoT devices. Principally it’s based on microkernel and designed for energy efficiency , hardware independent development and a high degree of modularity. However it has the potential to operate several platforms(

Embedded devices and PC’s) running both in 16 and 32 bit platforms. It has support for 6LoWPAN, IPv6, TCP and UDP.

Thing square Mist brings pliable wireless mesh networking and true Internet-connectivity to IoT.

Its an open source firmware and holds the advantage of being exceptionally light-weight and works with multiple micro controllers with a range of radios. It runs on a hardware with 64-256 kilobytes of flash and 16-32 kilobytes of RAM.

Pondering over some of the technologies driving this topic range from

NFC-its basically a set of short-range wireless technologies requiring a distance of 10cm or less operating at 13.56 MHzon ISO/IEC 18000-3 air interface and at rates ranging from 106kbit/s to 424kbit/s.NFC peer-to-peer communication is possible when both the devices are powered.

Bluetooth.

Wifi: technology that allows electronic devices to exchange data wirelessly over a computer network.

GSM(global system for mobile communications):it’s a digital cellular technology for transmitting mobile voice and data services. Luckily terrestrial GSM networks cover more than 90% of world’s population.

The Google i/o 2015 has come down with Google announcing project Brillo , that will power connected devices which are considered as a part of Internet of Things. Moreover Google also announced “Weave” , which is a set of developer tools that allow smartphones, the cloud and devices powered by Brillo to talk to one another. Its something like you use your smartphone to control a brillo powered gadget which routes your request from your phone through the cloud and to the connected Brillo-powered product.

Ever thought of devices that control and program themselves to adapt to your changing life. With Google Nest you can have the perfect experience and adjust it from anywhere just with a touch on your smartphone. Well nest comes with its 3 products- thermostat, Smoke+CO alarm and a camera. While the nest thermostat can controlled from your phone to work according to your temperature needs of your home ,the Smoke+CO alarm comes with a industrial-grade smoke sensor.its the first ever home alarm you can hush from your smartphone and can even tell what’s wrong and alert your phone. The nest cam can be used to monitor your home when you are away. It provides a 130 degree wide-angle view and you can even zoom in for a closer view. the best part is the nest cam can alert you if it sees any motion. Its even a good listener alerting you if it gets a hint of any intruder.

Well these were just a few examples to ponder , but by some years ahead we are gonna come of with plethora of such devices that can interact, connect and share data. Its like we are going to live in a world filled with sensors and data changing every moment manipulated to satisfy our needs. IoT doesn’t just react to what you need right now but it anticipates what you’re going to need by minutes from now. Its like living a life of serendipity

Internet of things is the next step to information revolution getting ready permute the world in a much relevant and smarter way. It’s the next generation.
