Clustering algorithm has an important effect on the performance of wireless sensor network. In this paper, energy efficient clusterbased routing (EECR) algorithm is proposed to prolong life time of wireless sensor networks. EECR selects the cluster-heads according to the two parameters remaining energy and node degree. Also cluster-heads select its members according to the two parameters of sensor remaining energy and the distance to its cluster-head. EECR is done in three phases quickly. Simulation results show that the proposed algorithm, increase the network lifetime more than 18 percent in compare of LEACH protocol.
