wsn protocol modified for cluster head selection

Cluster Head Selection in WSN based on Coverage preserving and Energy Eciency Cluster-heads are generally chosen either in a random manner or mainly based on nodes residual energy. Accordingly, there is no guarantee that network coverage is

In our work we extend the LEACH s cluster head selection algorithm in WSN based on different node characteristics like, density, centrality and energy. This paper focuses on increasing the lifetime of wireless sensor networks.
