Abstract:

In order to reduce the energy consumption of nodes and prolong the lifetime of wireless sensor networks (WSN), a routing protocol based on CPSO is proposed. The
protocol improves the cluster-head selection mechanism based on the Low Energy Adaptive Clustering Hierarchy (LEACH), it considers some factors like nodes’ residual energy,
distance to base station. It optimizes cluster-head selection by CPSO and then optimizes the communication between base station and cluster-head by multi-hop algorithm. The
simulation results show that the new protocol can save energy and prolong the lifetime of WSN compared with the LEACH.
