A MODIFIED MULTI-HOP ROUTING PROTOCOL FOR WIRELESS SENSOR NETWORKS USING PSO TECHNIQUE
Much work is carried out and a number of protocols to establish route and to improve energy efficiency were introduced to increase the lifetime of a Wireless Sensor Network (WSN) as the devices in these networks are powered by batteries which have limited energy. WSNs find diverse application in military, commercial, in health care, in vehicular movement control, for environment monitoring, to prevent crime, etc. The protocols used in these networks are not well balanced in case of consumption of energy. The energy consumption unbalancing causes hotspot issues which further reduces the networks lifespan. To surmount the issue a new protocol called PSO (Particle Swarm Optimization) Dependent Dynamic Clustering Multi-Hop Routing Protocol (PDDCMRP) which is based on PSO technique is proposed in this paper. In the proposed PDDCMRP protocol the clusters are formed dynamically whenever the failure of nodes takes place. Because of this the devices in each group (cluster) are balanced thereby balancing the consumption of energy of nodes during communication and this increases the lifespan of the network. Simulation results prove that PDDCMRP has good conduct in case of lifetime of network and energy usage issue compared to existing protocols.
