Abstract: Aiming at the energy balancing issue in wireless sensor network(WSN)，based on a local energy balancing metric,predicting-based distributed energy balancing routing (PDEBR) algorithm was proposed. PDEBR gets to energy efficiency with geographic location information and power control. PDEBR was complemented with distributed style.The simulation results show PDEBR can prolong network lifetime efficiently.

Key words: Wireless sensor networks, Energy balancing, Network lifetime
