摘　　要：针对移动自组网(Mobile Ad Hoc Network,MANET)中路由的广播风暴问题,提出了基于速度感知的可靠的概率路由发现(Speed-aware-based reliable probabilistic route discovery,SRPR)方案。SRPR方案利用节点的速度矢量信息,将节点划分为可靠节点和非可靠节点。再利用贪婪转发策略,将可靠节点集中选择离目标节点最近的节点赋予高的转发概率,进而提高路由的可靠性,降低路由跳数。将SPRP方案应用于典型的按需式距离矢量路由协议(Ad Hoc On-demand Distance Vector,AODV)进行仿真。仿真结果表明,提出的SPRP方案能够有效缓解广播风暴问题,降低控制包(Routing requests,RREQ)的重传次数,并减少碰撞率。For broadcast problem of routing in MANET, speed-aware-based reliable probabilistic route discovery （SRPR） scheme was proposed. SRPR considered speed vector and all nodes were divided into reliable nodes and un-reliable nodes. A node among reliable nodes closest to destination was assigned a high probabilistic routing decision by greedy forwarding strategy. The reliability of routing was improved and the number of routing hop was reduced by SRPR scheme. Ad Hoc On-demand Distance Vector （AODV） routing was adopted in the experiments. Simulation results show that the proposed routing protocol mitigates the broadcast storm problem and outperforms in term of number of re-transmission collision ratio of RREQ.
