The primary energy and balance of energy consumption of wireless sensor networks (WSNs) plays a key role in network lifetime and stability. However, the energy of each node and the total energy in wireless sensor networks are limited. In this paper, an efficient energy cluster-based routing protocol (EECRP) for wireless sensor network is presented and its properties are investigated. Its core is that using an uneven clustering method to organize network topology and particle swarm optimization (PSO) algorithm to optimize the clusters, which can settle the problem of hot spot and blind nodes, separately. Simulation results show that the consumption energy of each node is effectively balanced. At the meantime, network lifetime is greatly increased using EECRP.
