摘　　要：In order to save the energy and reduce the latency of the end-to-end transmission in mobile ad hoc networks an adaptive and distance-driven power control ADPC scheme is proposed by means of distance research in random geometrics. Through mathematical proof the optimal number of relay nodes and the optimal location of each node for data transmission can be obtained when a distance is given.In the ADPC first the source node computes the optimal number and the sites of the relay nodes between the source and the destination nodes.Then it searches feasible relay nodes around the optimal virtual relay-sites and selects one link with the minimal total transmission energy consumption for data transmission.Simulation results show that the ADPC can reduce both the energy dissipation and the end-to-end latency of the transmission.为减少MANETs中节点的能量消耗,并同时减少传输过程中端到端的时延,引入随机几何中距离研究的方法,构建出一种自适应的距离驱动功率控制方法(简称ADPC).经数学证明可知,任意给定一个距离,可以得出传输数据所需最优中继节点个数及最优中继节点位置.在ADPC中,源节点首先根据与目的节点间的距离,计算通信所需的最优中继节点数量及最优中继节点位置;然后在最佳中继节点周围搜索可行的中继节点,并选择一条总能耗最小的链路,进行数据传输.仿真结果表明,所提ADPC方法能够降低传输能耗、减少端到端的传输时延.
