摘要 基于IEEE 802.11 DCF MAC协议提出了一种适用于移动无线自组网的功率控制节能方案,在该方案中节点通过一种接收过程中的噪声功率预估计方法和RTS/CTS握手机制的反馈,动态调节待发送数据分组的发射功率。协议分析和NS2仿真表明,该方案在不明显降低网络吞吐量的同时,可以有效降低分组发射的平均功耗,从而达到节能的目的。 In this paper a power-saving scheme for mobile Ad hoc networks based on IEEE 802.11 DCF is proposed.Under the proposed scheme,the source node wilt regulate the transmit power of the data packets dynamically by the use of a method of pre-estimation of average noise power and the feedback of RTS/CTS handoffs during the reception.The protocol analysis and the simulation of NS2 show that the power-saving scheme is efficient to decrease the average transmit power of packets without reducing the networks throughput badly.
