Abstract：The conflict interference issue of the carrier sensing wireless network is investigated, and an adaptive power control mechanism of DCF protocol in Ad hoc networks is proposed. According to the communication status of the receiver, this mechanism adjusts adaptively the CTS frame transmission power of the receiver and the data frame transmission power of the transmitter which is decided by the receiver. The simulation results show that DCF protocol with this mechanism can not only save the average energy consumption of the nodes, thus prolong the lifetime of the network, but also can improve spatial reuse of the wireless channel, and improve the average throughput of the network significantly.
