Internet of Things

• It is the idea of enabling everyday objects with software, sensors and network connectivity.

• The connectivity would not only allow you to control them from afar but will also allow them to communicate and share data with each other.

• Google’s Nest Learning Thermostat, can tell when you leave the house and lower the temperature accordingly so as not to waste energy. It can learn and adapt itself according to your routine and adjust temperature accordingly.

My edit

Yes! It is still there.

What did the edit add to the topic?

• It is estimated that the IoT will consist of almost 50 billion objects by 2020.

• Since the internet lies at the core of IoT, the section on Network Architecture provides information on how will the architecture supporting this surge of internet connected devices look like.

Technical Aspects

IPv6• Internet Protocol version 6 (IPv6) is the most recent

version of the IP, the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet.

• Since the IPv4 addresses are about to get exhausted, it is being gradually replaced by IPv6.

• IPv6 uses a 128-bit address, allowing 2128, or approximately 3.4×1038 addresses, or more than 7.9×1028 times as many as IPv4, which uses 32-bit addresses and provides approximately 4.3 billion addresses.

6LoWPAN

• 6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks.

• The concept originated from the idea that “the Internet Protocol could and should be applied even to the smallest devices" and that low-power devices with limited processing capabilities should be able to participate in the IoT.

• It has defined header compression mechanisms that allow IPv6 packets to be sent and received over low rate networks.

Fog Computing• Fog computing, also known as fogging, is a

distributed computing infrastructure in which some application services are handled at the network edge in a smart device and some application services are handled in a remote data center, in the cloud.

• The goal of fogging is to improve efficiency and reduce the amount of data that needs to be transported to the cloud for data processing, analysis and storage.

• This is often done for efficiency reasons, but it may also be carried out for security and compliance reasons.

• In a fog computing environment, much of the processing takes place in a data hub on a smart mobile device or on the edge of the network in a smart router or other gateway device.

• This distributed approach is growing in popularity because of the Internet of Things (IoT) and the immense amount of data that sensors generate.

• It is simply inefficient to transmit all the data a bundle of sensors creates to the cloud for processing and analysis; doing so requires a great deal of bandwidth.
