Abstract: Wireless Sensor Networks (WSNs) comprise a huge number of tiny devices with restricted energy sources. Once installed, these nodes are generally unapproachable, thus auxiliary energy supply is not possible. Therefore, energy proficiency is a crucial design issue in WSNs. So, the energy efficiency is improved to extend the network lifetime. So as to decrease the energy usage of nodes and prolong the lifetime of network, a cluster-based routing algorithm with Particle Swarm Optimisation (PSO) is proposed in this paper. This proposed algorithm improves the cluster head (CH) election method as it deals with the residual energy of nodes and distance to sink node. It optimises CH selection by PSO. The conventional clustering schemes like LEACH and centralised version of it (LEACH-C) achieve better results in preserving the energy consumption. Thus, we compare our proposed algorithm with LEACH and LEACH-C. Simulation results confirm that proposed algorithm outperforms the LEACH and LEACH-C.
