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.
In order to reduce the energy consumption of nodes in MANETs and reduce the end-to-end delay in the transmission process, an approach of adaptive distance-driven power control (ADPC) We can see that given a distance, we can get the optimal number of relay nodes and the optimal relay node location for data transmission.In ADPC, the source node first calculates the distance required for communication based on the distance from the destination node The number of optimal relay nodes and the location of the best relay node, and then searches for feasible relay nodes around the best relay node and chooses a link with the lowest total energy consumption for data transmission. The simulation results show that, The ADPC method can reduce transmission energy consumption and reduce end-to-end transmission delay.
