摘　　要：为了在资源有限的移动Ad Hoc网络环境中提高网络能量效率、延长网络存活寿命,提出了一种面向移动节点不确定性特征的自组网路由协议.根据信息熵的相关理论,从移动节点的邻居节点集合的取值空间和取值空间中各邻居节点集合成员的具体分布来度量节点的不确定性,从统计和行为上对无线移动节点的动态特性进行刻画.对路由表项进行了扩展,增加了路由稳定性测度值域,以适用节点记录其到达路由请求分组源节点的路由稳定性测度信息.仿真结果表明,所提协议能够有效提高移动Ad Hoc网络的分组递交成功率和端到端分组延迟等性能,降低频繁路由重建和维护操作所产生的控制负载开销和能量消耗.A kind of routing protocol based on uncertain characters of mobile nodes in mobile Ad Hoc networks is proposed to improve energy efficiency and to extend lifetime of the networks with limited resources.The relevant theory of information entropy is used to measure the uncertainty of a mobile node from its value space of the neighbor nodes set and from the member distribution of the neighbor nodes set in the value space.The dynamic characteristics of wireless mobile nodes are described from the statistics and behavior,and the routing table entries are extended.The routing stability measurement values are added to record the routing stability measurement information when the node reaches the source node of the routing request packet.Simulation results show that the protocol can remarkably improve the performances of mobile Ad Hoc networks such as packet delivery ratio and packet end-to-end delay,and reduce control load overhead and energy consumption generated by frequent route reconstruction and maintenance.
