摘　　要：固定功率控制和随机功率控制策略对Ad hoc网络的连通性具有不同的影响。在理论推导的基础上进行数值仿真的结果表明,当网络中节点密度低时,固定功率控制策略的网络连通性较高;而当网络中节点密度较高时,线性分布的随机功率控制策略能提供较高的网络连通性。In this paper, We present stochastic analysis of the effect of two power schemes on the connectivity of wireless ad hoc networks： fixed power control and random control （RPC）. Using numerical examples, we show that RPC with linear probability control power density function has positive effect of reducing high interferences to the other nodes, and improves network connectivity in high-density networks. However, the fixed power control is more favorable in low-density environments.
