A framework for energy efficient routing protocol for homogeneous wireless sensor networks using sensing range

Wireless Micro Sensor Networks have unlimited applications all around us and these networks will enable the reliable monitoring in various environments for both civil as well as military purposes. Wireless Micro Sensor Networks are low power battery driven networks, hence efficient energy utilization is needed. In this paper focus is to design an optimum energy multi-hop network. For this purpose we propose the concept of merging in a multi-hop network in which if two sensing nodes are falling in the same sensing range then they will work in sleep and active mode as a result of which less energy will be used. Nodes are arranged in the form of clusters and each cluster has a cluster head. All the nodes communicate with Base Station using multiple hops via cluster heads. We will compute the energy used in network in terms of number of rounds of transmission and reception of information. Along with the efficient energy usage, our proposed merging algorithm helps in finding out the lifetime of network (in number of rounds).
