摘　　要：In sensor networks, the selection of the transmission power level influences the network topology, power consumption and packet reception rate. In this paper, we analyze the effects of power control in the scenario of body sensor networks. A joint power control strategy considering both the MAC layer and the routing layer is also proposed. Simulation results show it achieves very good performance on both reliability and power efficiency.
