摘　　要：随着我国城市轨道交通行业快速发展,当前城市轨道交通系统难以满足下一代城市轨道交通车地通信需求.研究表明采用无线自组网路由技术能够改善城轨系统通信性能.基于城市轨道交通无线自组网的组网架构,提出提前配置全局路由信息,减少路由发现消耗的时间,从而提高传输效率;在路径选择中,根据业务需求对路径数量进行约束,并基于链路代价选择跳数小、质量高的路径,从而提高数据传输的可靠性.通过MATLAB仿真结果表明,基于业务需求约束的多路径路由比传统的AOMDV路由更有利于满足下一代城市轨道交通车地通信需求.With the rapid development of China s urban rail transit industry,the current urban rail transit system is difficult to meet the next generation of urban rail transit vehicle-ground communication needs.The studied shows that the use of wireless ad hoc network routing technology could improved the communication performance of urban rail transit system.Based on the networking architecture of urban rail transit wireless ad hoc network,it proposed to reduce the time spent on route discovery by configuring global routing information in advance.During the path selection,the reliability of data transmission was improved by constraining the number of paths according to service requirements,and the path with low hop count and high quality could be selected based on the link cost.MATLAB simulation results show that multi-path routing based on service demand constraints is easier to meet the communication needs of next-generation urban rail transit vehicles-ground than traditional AOMDV routes.
