Power Control in Mobile Ad Hoc networks is a critical issue, since nodes are powered by batteries. The main idea of power control schemes is to use different power levels for RTS/CTS and DATA/ACK. These schemes may degrade network throughput and reduce energy efficiency of the network. In this paper the authors have evaluated the performance of Improved Autonomous Power Control MAC Protocol (IAPCMP)that allows nodes to dynamically adjust power levels for transmission of DATA/ACK according to the distance between the transmitter and its neighbors. In IAPCMP power level for transmission of RTS/CTS is also adjustable. This also used maximum power level for transmitting DATA/ACK periodically to make neighboring nodes aware about ongoing transmission.
