摘要 提出了一种基于效用转发的自适应机会路由算法URD,并从理论上对该算法的有效性进行了分析。通过DTN仿真软件ONE进行了具体实现和验证,并与其他的经典协议:Epidemic,PRoPHET和SprayAndWait进行了性能对比。仿真结果表明,URD算法能够增加节点相遇的可能性,提高数据分组转发的效率,减少了网络的时延开销。 An adaptive opportunistic routing algorithm based on utility called URD was proposed,and then the effectiveness of this algorithm was analyzed.At last,this algorithm was implemented using Java by ONE simulation tool and its performance was verified with the classical algorithms：Epidemic,PRoPHET and SprayAndWait.Simulation results show that URD algorithm can increase the probability of encountering opportunity between nodes,improve the efficiency of forwarding packets and reduce the delay overhead of network.
