Improved Clustering Algorithm for Energy Saving in Wireless Sensor Networks

Clustering is a characteristic method in hierarchical topology controlling in wireless sensor networks. In the paper, we considered the rest of energy of every node in the process of clustering, and proposed an improved clustering algorithm for energy saving. This algorithm is realized by calculating the number of cluster head, choosing the optimal head, decreasing the energy consuming in cluster reconstruction, and cutting down the data processing or transferring of every node. Finally, the simulation result in NS2 presented that the number of living node is obviously more than LEACH algorithm.
