A Balanced Cluster Routing Protocol of Wireless Sensor Network

Energy efficiency has been known as the most important problem in wireless sensor networks. As a classic clustering-based protocol LEACH do a tremendous contribution on energy efficiency. But it has some drawbacks that the cluster head may not well distributed, and the number of nodes in each cluster is distributed unequally. In this paper we proposed a new protocol BCBE (Balanced Cluster and Balanced Energy), the advantage of this routing protocol is we only have to know the location information of two nodes to locate other sensor nodes. The key feature of the protocol is: balanced cluster, balanced energy dissipation, hierarchical routing and load balance. Simulation results show that the proposed routing protocol can achieve longer network lifetime than LEACH.
