A Weighted Clustering Algorithm Based Routing Protocol in Wireless Sensor Networks

The wireless sensor network is a type of the wireless ad-hoc networks. It is composed of nodes with limited battery power. One of the most critical issues in designing wireless sensor networks is to minimize the energy consumption for longevity. In this paper, we first entirely analyzes state clustering protocol and LEACH routing protocol, then present a novel clustering routing protocol for wireless sensor networks, which elects clusters by using weighted clustering algorithm. At last, simulations are given for the protocol proposed with NS. Simulation results show that this protocol can reduce overall energy consumption and improves network lifetime.
