A PSO Based Energy Efficient Clustering Technique for Wireless Sensor Network

Wireless Sensor Networks (WSNs) is one such technology which plays a pivotal role in our day to day life because of its wide range of applications. A wireless sensor network (WSN) as the name suggests is a wireless network with distributed autonomous devices making use of sensors for monitoring physical as well as environmental conditions. Two main challenges in the field of WSN are efficient energy consumption and route optimization. In the proposed system Basic AODV Protocol is used with the implementation of PSO based clustering. AODV provides a route for communication between the various nodes where as cluster head is selected by PSO on the basic of their distance from the cluster member node to sink node. Performance evaluation of AODV and AODV-PSO is done on the basic of following performance metrics like Total Energy Consumed, Load, Average delay, Average Throughput and Packet delivery ratio. Simulation results show that AODVPSO is much better as compare to AODV.
