Subtractive Clustering Based Clustering Routing Algorithm for Wireless Sensor Networks

Based on LEACH(Low-Energy Adaptive Clustering Hierarchy) algorithm,a new algorithm named SCC(Subtractive Clustering based Clustering routing algorithm for wireless sensor networks) is proposed.In SCC,the subtrac-tive clustering method is used to choose the cluster-heads and generate the cluster-heads where the node density is high;besides,the current non-cluster head attribution mechanism is modified to distribute the expenditure of energy averagely into the whole network.Simulation results show that the SCC algorithm can provide the reasonable arrangement of cluster-head,longer lifetime of the first node and even longer lifetime of the network to balance the energy expenditure of all the nodes in the network.
