Organizing wireless sensor networks into clusters enables the efficient utilization of the limited energy resources of the deployed sensor nodes. Oftentimes the network is organized into clusters of equal size, but such equal clustering results in an unequal load on the cluster head nodes. Instead, we propose an Unequal Clustering Method (UCM) for network organization, which can lead to more uniform...
In clustering algorithm of wireless sensor networks, to solve the problem of excessive energy consumption in the cluster heads, an residual energy and node position synthesized grid-based distributed topology control algorithm is proposed in this paper. In cluster heads election phase of every round, it considers the residual energy and the average energy of all the nodes in each cluster, an optimal...
