Energy-Efficient Clustering Hierarchy Model for Wireless Sensor Network

The main goal of research for wireless sensor network is to minimize the energy consumption of each node, and maximize the network lifetime. We divide the network into many unequal clusters. According to different distance to the Sink, the clusters head are in charge of different geographical scope, which could reduce the internal energy consumption of the cluster headers near the sink relatively, thus energy consumption of WSN is relatively evenly distributed, in result, improve energy utilization and prolong the life of the entire Wireless Sensor Networks effectively.
