Analysis of energy consumption for a biological clustering method in sensor networks

In this paper we present an analytical model for per-formance evaluation of a clustered sensor network. We examine the energy required for a single round of cluster-ing for a biologically-inspired extension of the well-known LEACH clustering method. We use methods from stochas-tic geometry to model the locations of the node clusters us-ing a hard-core Matérn cluster process. Based on the com-putation of the energy consumption of the whole clustering procedure we determine the most energy-efcient setting of the cluster radius. Furthermore, we consider the efciency of clustering when the sensed data can be compressed at the cluster heads. 1
