Adaptation Layer (6LoWPAN) for Industrial Internet of Things

Speaker:  Pradeep Kumar TS – Chennai, India
Topic(s):  Networks and Communications


Internet of Things is powered by a small data rate physical layer called ZigBee (IEEE 802.15.4) which works with a small data rate and that can handle a MTU (Maximum transfer unit) of just 127 bytes. But the industrial internet of things demands IPv6 for addressing the nodes which has the MTU of 1280 bytes. So how, such a huge packet pass via the ZigBee., The answer is 6LoWPAN.

To understand Internet of Things, the first level of information needed is the IoT layers verses the OSI Layers. This lecture elaborates the basic understanding of these layers. This lecture also deals with the complete specification, packet format, frame structure, compression of 6LoWPAN along with the dispatch codes used in 6LoWPAN. Since Industrial IoT needs the implementation of this adaptation layer too, this lecture deals with the implementation feature of 6LoWPAN by featuring various Operating systems that supports 6LoWPAN. 

This presentation compares various operating systems for their speedier implementation of 6LoWPAN that of others.  A small case study on how to deploy this adaptation layer into the networking devices (Preferably the motes) and program it to display the sensed information in the browser via CoAP protocol. The CoAP is not mentioned here as it is in the Application layer which just work the limited edition of the HTML protocol. 

Instead, this lecture also features the RPL (Routing protocol for Low Power and lossy networks) that sits between the transport layer and the application layer that just works fast and enables the smoother operation of 6LoWPAN.  RPL is dealt with its control messages, rank formation and topology formation for better reliability of this protocol.
