EW-LEACH: Energy Weight-Based Routing Techniques in WSNs

Abstract:

Wireless Sensor Networks (WSNs) play more and more important role in all kinds of applications. Because of its characteristics, energy consumption is an open issue in research field. In LEACH Cluster Head (CH) is selected randomly without any parameter, such as node energy, distance. There exists a probability that energy consumption is unbalanced in WSN, which causes shortening its lifetime. In this paper, we proposed a new LEACH-based protocol, Energy Weight LEACH (EW-LEACH). The main purpose of EW-LEACH is to provide important parameters, node energy, to determine the CH selection strategy. Node energy acts as a weight to alter the probability that a node becomes CH. The results of simulation show that EW-LEACH increases energy efficiency and prolong the network lifetime.
