Cluster Head Load Distribution Scheme for Wireless Sensor Networks

This paper proposes an optimal load distribution scheme in cluster head and cluster members nodes for wireless sensor networks (WSN). Proposed load distribution model is based on associative clustering model, guided by residual energy and load of the sensor nodes in a cluster. Energy hole can be avoided in this scheme by uniform load distribution in the clusters. An efficient data routing is also performed through the clusters to the base station using multi-hop technique. Simulation results show that our proposed scheme outperforms the existing algorithms in terms of the network lifespan, and optimal load distribution. Time efficient routing is also established within a cluster.
