摘要：

Due to the constrained energy of nodes and no further energy to be supplied in wireless sensor networks, how to reduce energy consumption of nodes becomes the important target of routing protocols. An energy efficient routing protocol based on cluster head forecasting and power controlling(CHFPC) is proposed. In CHFPC, cluster head is forecasted by energy and distance parameters, and power controlling is introduced into cluster routing and data transmission so as to reduce the average energy consumption of nodes. Finally, the performance of the CHFPC algorithm is simulated in OMNeT++. The results show that the proposed scheme outperforms LEACH by 23% and 15%, respectively in terms of the lifetime and total residual energy of wireless sensor networks, and the time till a node dies for the first time in CHFPC is longer than that in LEACH as the initial energy of each node varies.
