In this paper, Adaptive Power Control with Overhearing Avoidance (APC+OA) has been proposed. The proposed power control algorithm has been implemented in PICSENSE wireless sensor nodes. The energy consumption of proposed MAC has been compared with that of On Demand Transmission Power Control (ODTPC) protocol and it is shown that the Adaptive Power Control with Overhearing Avoidance gives higher energy conservation compared to ODTPC. The power level convergence towards the optimal power for APC-OA is two times faster than the ODTPC
