摘　　要：近几年,对Ad Hoc网络的研究已经成为一个研究热点。基于距离的动态概率算法是在概率算法和距离算法的基础上,根据Ad Hoc网络中节点间的距离动态地调整转发概率。给出了NS-2下的仿真结果,从中可以看出,基于距离的动态概率算法比概率算法和距离算法具有更好的性能。In recent years, . the research of the Ad Hoc network is becoming one of the focuses. In this approach, the dynamical probabilistic scheme based distance is based on the probabilistic scheme and the distance-based scheme to adjust dynamically the rebro- adcasting probability according to the distance between each node in Ad Hoc network. The simulation results under NS-2 are presented, The numerical results show that the dynamical probabilistic scheme based on distance works well than the probabilistic scheme and the distance-based scheme.
