MULTI-LEVEL ENERGY EFFICIENT IMPROVED UNEQUAL CLUSTERING IN WIRELESS SENSOR NETWORKS

In wireless sensor networks (WSNs), the node distribution in the unequal clustering is rapidly used for distributing the load and increase the network lifetime. In tradition unequal clustering mechanism, the nodes which are nearer to the base station suffers with energy depletion. To overcome this issue, this paper proposes the multilevel unequal clustering algorithm with efficient cluster head selection procedure based on the residual energy and maximum transmission capacity of the nodes. The proposed algorithm uses threshold function to resist the waiting time of the node for receiving the cluster head notification message. The simulation results show the efficiency of the proposed algorithm compared with the counterpart algorithms
