Abstract :
The letter identifies a power control induced hidden terminal problem, named POINT problem, and proposes a collision avoidance power control (CAPC) MAC protocol to solve the POINT problem for wireless ad hoc networks. CAPC takes the interference range into consideration and uses the appropriate power to exchange Data/ACK, instead of the exact power in order to resist the interference of other stations. Simulation results verify that CAPC can effectively prevent the POINT problem.
