Clustering algorithm for improved network lifetime of mobile wireless sensor networks

Abstract

In this paper, we propose LEACH-CCH as a clustering algorithm aimed at improving wireless sensor network lifetime in the case of mobile sensor nodes. LEACH-CCH is a modification of the LEACH algorithm, which was developed for stationary networks. An analysis of energy consumption for the LEACH algorithm is presented to identify which data transmissions are most energy expensive for a node throughout its lifetime. LEACH-CCH reduces the energy expended during the costliest data transmission. By predicting the future positions of sensor nodes and restructuring clusters accordingly, an improvement is seen in overall network lifetime when compared with LEACH.
