One of the Most Important Problems in Wireless Sensor Networks Is Energy-efficiency Routing Protocol Design. In This Work we propose a hierarchical Clustering Method For energy conservation in Wireless Sensor Networks. First, we divide the sensor nodes to Small Size clusters and determine a cluster head for each cluster in the network. The residual energy and distance to BS are parameters for CH election In clusters. Simulation Results Show that our Proposed Algorithm is Energy-efficient and has optimum performance with comparing to leach.
