摘　　要：对多类点Adhoc网络及网络中出现的单向链路问题进行了研究,设计出一种基于单向链路的Adhoc路由策略,通过检测并使用单向链路可提高网络的连通性能,同时可采取措施降低控制开销.仿真分析结果表明,该路由策略在控制开销方面优于传统路由机制,而路由成功率和吞吐量性能降低很小.Based on heterogeneous Ad hoc network,study of unidirectional link,low overhead routing based on unidirectional link（LORUL）is designed,LORUL can improve the network connectivity by the detection and use of unidirectional link,it also decrease control overheard by special method.LORUL is evaluated in simulation,it is shown that the performance is better than the traditional routing mechanism on the control overheard,the decrease on the end-to-end delay and the throughput is quite small.It is also shown that LORUL suits for the scenario with low node density.
