An approach for energy optimization in wireless sensor networks

Wireless sensor networks (WSN) are lately an object of significant attention due to their unlimited potential and many areas of implementation. Many sensor network applications require prolonged network lifetime, scalability, and load balancing. Organizing sensor nodes in clusters is an effective technique for satisfying these goals. In this paper we present a study on the optimal number of cluster and the effective radius of the clusters in wireless sensor networks (WSN). Based on the results we investigate the energy dissipation in a single node and the whole network, and propose a scheme, which extends the network lifetime, due its lightweight architecture.
