Aiming at the unbalanced problem of nodes'energy consumption in LEACH protocol, this paper proposes a clustering algorithm of cluster head optimization based on energy (LEACH-E). In LEACH-E, we introduces a threshold value, which depends on the probability of optimum cluster head in network and the residual energy of nodes, to optimize the selection of cluster head. Consequently, LEACH-E can effectively avoid the possibility that the node with low energy is selected as the cluster head, and balances the energy consumption of nodes. Simulation results show LEACH-E can prolong the network lifetime efficiently compared with LEACH protocol.
