PROJECT TITLE :

Co-operative routing for wireless sensor networks using network coding

ABSTRACT:

Omni-directional 2-manner traffic flow using flooding ends up in broadcast storm problem in a very wireless sensor network (WSN). The probabilistic routing protocols help in reducing the broadcast storm but lack reliability. Network coding may be a new paradigm that allows an intermediate node to encode incoming packets that improves the bandwidth potency and reliability of the WSN. A network coding-based probabilistic routing (NCPR) theme has been proposed, that is energyefficient, reliable and alleviates the broadcast storm drawback in a clustered WSN. The focus of this work is to design the network coding-primarily based procedures for probabilistic routing protocols. In NCPR, a sensor node initialises a transmission method during a WSN cluster by transmitting a packet from its sensed queue. Every neighbour node encodes its received packet with its sensed packet using XOR network coding and transmits the coded packet with sure probability. Three network coding-based procedures are proposed for encoding and decoding of packets in intra-cluster and inter-cluster communications by distributing roles among the sensor nodes. It has been shown that the NCPR scheme provides higher energy efficiency and reliability compared to the probabilistic routing and pure flooding schemes.
