摘要
Power control technology in wireless sensor network (WSN) is of great significance to ensure the network coverage, reduce the power consumption of the nodes, and optimize network performance. In this paper, a new power control based on routing protocol (PCBRP) in the MAC layer is proposed. It operates with the help of routing protocol and calculates optimal transmission power according to the distance between neighbor nodes. A mapping table including optimal transmission power and node's address is established during the route building procedure. The transmission power can be gotten through searching the table with the address of next hop in latter data transmission. Finally, we implement the PCBRP scheme in a real system and set up a test-bed to illustrate its operations.
