摘　　要：现有无线Ad Hoc网络路由协议的应用都基于节点间链路是对称的假设,但由于节点发射功率、电源消耗以及周边环境等影响,链路非对称的情况是普遍存在的。基于这个前提,目前提出的解决方案多数采用设置邻居节点列表,使用共同邻居节点告知的方式解决。讨论了现有解决方案的处理方式,并建立模型对非对称链路解决方案的性能进行分析。Routing protocols for wireless Ad hoc networks are based on the hypothesis of symmetric link. However, because of the influence of radio power, battery outrage, natural environment, and so on, asymmetric link is prevalent. At present, projects to solve this problem are mostly setting tables of neighbours, and using the corporate neighbours to inform the node whose region is larger. The solution of asymmetric link is discussed, and the model has been built to analyze the performance of these solutions.
