In this paper, we propose an Improved Power Control MAC (IPCM) protocol which improves the throughput and yields energy saving. This protocol sends all the packets RTS, CTS, DATA and ACK with optimal transmit power, which save the energy, makes spatial reuse of the wireless channels, and achieves the maximum throughput. On the other hand, the power of the data packets is periodically raised to a suitable level (Pai) to avoid the interference but not to the maximum so that it will not create unnecessary contention between nodes. The power level of Pai is based on finding the optimum carrier sensing range that increase the network capacity and reduce the interference effect of the ongoing transmission. Our simulation results show that IPCM protocol scheme can achieve high reduction in energy consumption and also improves the throughput efficiency compared to the other schemes.
