IoTAn Introduction

THE INTERNET•Technologists say, “the world has turned to a ‘Global Village”. Well, the credit to this goes to the ‘Internet’.•The Internet has made distances shorter and the world smaller.

•In a matter of very few years, the Internet consolidated itself as a very powerful platform that has changed forever the way we do business, and the way we communicate. •Size of Internet – Expanding Daily. Every hour, every minute, rather every second.

•The Internet is defined as the worldwide interconnection of individual networks operated by government, industry, academia, and private parties. 

PRESENT SCENARIO

Can We Have Such A Day?

Well Actually, we already have it!

IoT – The Magic Term!

What is ‘IoT’?

It is an elusive concept.

The Internet of Things (IoT) is the interconnection of uniquely identifiable embedded computing devices within the existing Internet infrastructure.

IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications and covers a variety of protocols, domains, and applications.

The interconnection of these embedded devices (including smart objects), is expected to usher in automation in nearly all fields, while also enabling advanced applications like a Smart Grid, a modernized electrical grid that uses analog or digital information to gather and act on information, such as information about the behavior of suppliers and consumers,.

IoT – A Brief HistoryThe‘IoT’ Timeline

The concept of a network of smart devices was discussed as early as 1982, with a modified Coke machine becoming the first internet connected appliance, able to report its inventory and whether newly loaded drinks were cold.

 In 1994 Reza Raji described the concept in IEEE Spectrum as "moving small packets of data to a large set of nodes, so as to integrate and automate everything from home appliances to entire factories.“

However, only in 1999 did the field start gathering momentum. Bill Joy envisioned Device to Device (D2D) communication as part of his "Six Webs" framework, presented at the World Economic Forum at Davos in 1999. Kevin Ashton, who is often regarded as the originator of IoT, first proposed the term "Internet of Things" in the same year.

• In a word: Sensors. • Many IoT devices have sensors that can register

changes in temperature, light, pressure, sound and motion.• These sensors are part of a device category called a micro electromechanical system (MEMS) and are manufactured in much the same way microprocessors are manufactured.

• This is a circuit with a limited degree of programming capability and is hardwired to do something specific.

What it takes IoT to function?

The Primal Challenge

How do IoT devices communicate?

• An IoT device will have a radio that can send and receive wireless communications. • IoT wireless protocols are designed to accomplish some basic services:

1) Operate on low power 2) Use low bandwidth 3) Work on a mesh network.

• Some work on the 2.4 GHz band, which is also used by Wi-Fi and Bluetooth, and the sub-GHz range.

• The sub-GHz frequencies, including 868 and 915 MHz bands, may have the advantage of less interference.

Why is low power and low bandwidth important in IoT?

• Some IoT devices will get power from electrical systems, but many, such as door locks and standalone sensors, will use batteries. • These devices send and receive small amounts of information intermittently or periodically. Consequently, the battery life of an IoT device can range from 1.5 years to a decade, if the battery lasts that long. • One IoT maker, Insteon, uses both radio and powerline communication,which can send data over existingelectrical wiring as well as via a radio, which it says will offer an increased measure of reliability.

Will I need a gateway or hub in the IoT?

• A gateway, bridge or hub provides a connection point between your home network and other devices.

• The hub works with your home router and provides communications to the machines, devices and sensors that are part of your IoT universe.

• This will also be true for the washing machine that is connected to a smart metering system and starts a wash only when electric rates are at their lowest point.

• These connections will be established through hubs that support multiple wireless technologies.
