摘　　要：对重叠无线Ad Hoc网络的进度密度进行了定义,推导了主网络和次网络的进度密度表达式,研究了主网络的最大中断概率增量对主、次网络进度密度的影响。数值分析和仿真结果表明:次网络的干扰会使得主网络的中断概率增大,导致主网络的进度密度减少;次网络的进度密度随着主网络最大中断概率增量的增加而迅速增大;使用重叠无线Ad Hoc网络后,主、次网络的进度密度之和会大于主网络单独存在时的进度密度,使用重叠无线Ad Hoc网络的关键是设置合理的最大中断概率增量。This paper defined the density of progress in overlaid wireless Ad Hoc networks, derived the expressions of the density of progress in the primary network and secondary network, and studied the effect of the maximum increment of the probability of outage for the density of progress in the primary network and secondary network. Numerical and simulation results show that： for that the interference from the secondary network would increase the probability of outage of the primary network, the density of progress of the primary network would decrease; the density of progress of the secondary network would increase rapidly with the maximum increment of the probability of outage; the sum of the density of progress of the primary network and the density of progress of the secondary network is more the density of progress of the primary network when there no the secondary network, and how to set a proper value for the maximum increment of the probability of outage was the most important thing to do before using the overlaid wireless Ad Hoc networks.
