摘　　要：针对现有的无线传感器网络传输功率控制算法未充分考虑实际信道干扰的问题,给出了基于干扰估计的最优传输功率计算方法;考虑到通信信道及活跃节点数目的时变性,提出了自适应速率调整算法;最后通过试验验证了所提方法的可行性。In view of problem that existing transmission power control algorithms of wireless sensor network do not take full account of actual channel interference, calculation method of optimal transmission power based on interference estimation was given. An adaptive rate adjustment algorithm was proposed in consideration of time-varying characteristics of communication channels and the number of active nodes. Finally feasibility of the proposed method was verified through experiments.
