How to use limited power resources to extend the network lifetime has become an important issue in this field. In wireless sensor network (WSN), sensor nodes deliver the collected data back to the sink using multiple-hop routing paths. This paper proposed an Energy-aware Power-Level Control routing (EPLC) mechanism for wireless sensor networks. The algorithm uses four power levels to adjust the sensing and transmission range of sensor nodes. Both minimum hop and maximum available power routes are considered to achieve load balancing. Finally, sleep and wakeup mechanism is implemented to further extend the lifetime of the network. Simulation results show that our algorithm outperform previous results.
