A Clustering Approach Based on Genetic Algorithm for Leach Protocol

Abstract

Wireless sensor networks have many nodes with limited energy that distributed in a limited geographical area and be able to monitor surroundings. The fundamental problem in WSNs protocol design and development is limited energy resources of sensor nodes in the network. In this paper an effective clustering approach for selection of cluster heads in wireless sensor network is introduce by using Genetic Algorithm for load balancing and increasing network lifetime. The approach is based on LEACH. In approach single-hop technique is used for communication within the cluster and cluster head to BS. For cluster head selection each node evaluates its density and energy, with an internal function. Simulation results show that the proposed approach effectively produces optimal cluster heads for the wireless sensor networks, and resulting in an extension of lifetime for the network.
