Abstract

In the era of computing technology WSN is playing significant role in human life by helping environment monitoring, health monitoring, habitat monitoring and military applications. In cluster based WSN network energy can utilized optimally to enhance the lifetime by uniform distribution of nodes among the clusters and avoiding redundant data transmission from sensing nodes to sink through balanced utilization of network energy. In dense WSN, nodes in the same sensing range collects the same data and hence it is not required for all the nodes to transmit the data to the Cluster Head. This paper proposes a method which uniformly attaches the nodes to Cluster Heads and avoids the duplicate data transmission from different nodes in the same sensing range thereby conserving energy. The proposed method distributes the nodes uniformly and checks the residual energy among the nodes having the same data to allow the node with more residual energy to transmit the data to the cluster head. This results in increase of 3% alive nodes compared to earlier method5, leading to an increased lifespan.
