Wireless Sensor Networks (WSNs) consist of a large number oflow-power nodes sensing data from the environment. The sensor nodesare equipped with small and often irreplaceable batteries withlimited power capacity. One of the areas of sensor networking thathas attracted a lot of attention recently is the prolonging of thelife span of sensor networks by exploiting energy-efficient routingschemes. We propose a novel energy-efficient centralised clusteringalgorithm for WSN. The proposed algorithm generates a set ofpossible clustering alternatives from which it selects the optimalclustering. We also present a performance evaluation of theproposed algorithm using two performance metrics Max-min andMax-sum. We found that Max-sum yields superior performance. Inaddition, our proposed algorithm improves the system lifetimeperformance over Low Energy Adaptive Clustering Hierarchy-C byalmost 15%. We also compare performance results obtained with thechosen metric (Max-sum) with those obtained using other strategies(such as random and configuration 0). The Max-sum metricoutperforms the random and configuration 0 strategies by almost 8.5and 11%;, respectively, for system lifetime. Moreover, we foundthat the total amount of data collected using the Max-sum metric isat least 9% higher than with random and configuration 0strategies.
