Optimization of clustering process in heterogeneous wireless sensor network

Abstract: Wireless sensor Networks are resource constrained systems that needs efficient utilization of all resources. With the limited capabilities of sensor nodes in terms of energy resources, processing and communication range, the cluster based protocols (clustering protocols) should be compatible with these constraints. Clustering provides an effective method for enhancing the lifespan of wireless sensor network. Optimization of clustering process improves overall performance in terms of cluster head selection, cluster balancing, aggregation and communication.

Keywords: Energy optimization, clustering, communication, aggregation and lifespan..
