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.
Fog Computing
• 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.
