摘要 对基于优化链路状态协议(OLSR)和源路由的多径路由算法(SR-MPOLSR)进行仿真分析发现,由于网络拓扑信息不完整和多径耦合问题,SR-MPOLSR难以找到源路由路径,并且难以提高端到端分组传递的成功率.为此,对OLSR协议进行了扩展,增加了冗余扩散、代理发布和代理选择功能,以获得网络完整的拓扑结构;设计了一种耦合因子为0的多路径选择算法,以避免同源多径业务流之间的相互干扰.仿真实验表明,在大业务量的情况下,改进算法分组投递的成功率比原算法提高约10%. The OLSR（optimized link state routing） and source routing-based multipath algorithm（SR-MPOLSR） was simulated.The simulation results indicate that the SR-MPOLSR has disadvantages in finding a source routing path and can not improve the success rate of end-to-end packet transmission because of uncompleted topology information and multipath coupling problem.In order to get the complete structure of network topology,redundant diffusion,agent announcement and agent selection were extended on OLSR.A multipath selection algorithm with a coupling factor 0 was proposed to avoid interferences among multipath flows from a same source.The research results show that the end-to-end packet success rate of the improved algorithm is approximately 10% higher than that of the SR-MPOLSR in heavy network load conditions.
