Abstract

This paper computes the optimum number of cluster heads based on power first, and then proposes the clustering algorithm for WSNs, at last estimates its performances by our emulator. On analysis, clustering time complexity is dependent on the network diameter and it is suitable for small or medium networks. The simulation results show that using this clustering algorithm can generate network topology of optimum number of clusters, the nodes energy is reduced greatly and the lifetime of networks is extended.
