A New Clustering Routing Algorithm of Wireless Sensor Network

In wireless sensor network, node’s energy is limited. The energy consumption of transmission a bit is larger than that of handle a bit. If it adopt effective routing algorithm, it can greatly improve the energy efficiency of wireless sensor network. In order to improve the energy efficiency of wireless sensor network in the large area, we propose a clustering routing algorithm based on energy, the algorithm realize the multi-hops communication between cluster heads by dividing the WSN area into concentric rings, and reduce the size of radius of the clusters gradually when the nodes’ energy is decreasing slowly. The results of simulation show that the algorithm can effectively prolong the network lifetime.
