摘　　要：针对如何让机会路由适应动态环境和避免不可靠的传输两个重要问题,提出一种在移动Ad hoc网基于链路质量和局部拓扑信息的机会路由协议(OR-LqT)。该协议首先综合考虑干扰和节点的移动性去衡量链路质量,为每个节点选出候选节点集合,然后依据节点位置,局部拓扑信息以及移动适应性评定候选节点的优先级,选出合适的转发节点;最后,通过NS2仿真实验将其与传统的路由协议相比,验证网络性能的提升。In view of the two important problems of letting opportunistic routing adapt to the dynamic environment and avoiding unreliable transmission,this paper proposes an opportunistic routing protocol(OR-LqT)based on link quality and local topology in Ad hoc net.In the protocol,the mobility of interferences and nodes is considered to measure link qualities,in order to find a candidate set for each node;and then the priority of candidate nodes is determined by local topology information and moving adaptability according to node’s location,in order to select a next forwarding node;finally,NS2 simulation experiment is made to compare OR-LqT with the traditional routing protocol,in order to verify the performance of the net.
