摘　　要：针对移动自组织网络中的路由建立和维护问题,研究了衡量路由稳定性的准则,以节点的不确定性特征作为路由选择的标准,提出了基于局部拓扑结构变化熵度量的稳定路由选择策略,并在此基础上设计了一种稳定路由协议。通过NS-2仿真软件对路由选择策略和路由协议进行了验证,仿真结果表明所提出的稳定路由选择策略和路由协议能够有效地提高移动自组织网络的性能。To deal with the route establishment and maintenance problems in mobile ad hoc networks,this paper studies the metrics for selecting stable route.By using the degree of uncertainty about the nodes as the measurement standard for route selection,it proposes a stabile route selecting strategy based on the local topology transformation entropy.This paper also designs a kind of stable route protocol.The NS-2 simulator is used to validate the route selecting strategy and route protocol,and the simulation results show that the route selecting strategy and route protocol can improve the network performance remarkably.
