Research of Optimal Energy Consumption Model in wireless sensor network

In wireless sensor network (WSN), the total energy is restricted, how to make good use of the limited energy resource is a very important aspect in the research of WSN. In this paper, a more reasonable energy consumption model is proposed: Optimal Energy Consumption Model (OECM). Under the new model of energy consumption, different network parameters can obtain different optimal clusters. It is different from LEACH algorithm which has the same clusters for any WSNs if the number of node is a constant. The simulation results show that the optimal number of cluster heads is not only related with the number of the nodes n, but also with the radius of the network R, packet length L and circuit energy dissipation.
