A Clustering Routing Algorithm for Wireless Sensor Network with Balanced and Efficient Energy

In order to reduce the average energy consumption of a cluster in Wireless Sensor Network(WSN) clustering routing protocol,and solve the problem of unbalanced energy consumption of cluster head near the sink node,this paper presents a new algorithm called Balanced Energy Efficient Routing Algorithm(BEERA).It contains constructing the energy consumption model and providing the routing algorithms of BEERA,discusses a series of key issues such as how to calculate the best competitive radius,select the cluster heads,establish forwarding path among the clusters and generate the clusters.Simulation results show that BEERA prolongs the WSN lifetime effectively compared with Leach and other protocols.It has higher feasibility and stability with the duration of stable period achieved by 19.6%～129% and the turns number improved by 22.8%～58.6% when entering into HRD phase.
