Abstract

Wireless Sensor Networks (WSN) consist of high node density, which are highly resourceconstraint in terms of size, power and bandwidth. The energy optimization in sensor nodes is very important design challenge for Wireless Sensor Networks. Clustering is the important technique to save energy. In this paper, Connected Dominating Set (CDS) generated by clustering is used to select the workers and sleepers of the network; it will be depending on the transmission range of each node. The transmission range optimization is a key issue to obtain energy conservation in WSN. But there is a trade off between transmission range and the number of route hops, node density and traffic load. In this paper, the comparisons of energy efficiency for uniform and random node densities are carried out for the optimal transmission range for energy consumption using an energy consumption model. The simulation results using NS-2 simulator is compared in an effective manner.
