A PSO based fault tolerant routing algorithm for wireless sensor networks

Abstract

The main source of energy consumption in the wireless sensor network is due to transmission and receiving of data packets. However the cluster head (CH) near to the base station (BS) in cluster based wireless sensor network depletes energy faster and die quickly due to transmission of heavier data traffic of other CHs to the BS. In this paper we propose a particle swarm optimization (PSO) based approach which construct the routing path and distribute the routing load over the CHs near to the BS and maximize the lifetime of networks. We also consider the fault tolerance issue due to the sudden failure of CHs during data routing phase. The simulation results show the effectiveness of the proposed algorithm over the existing algorithms.
