摘　　要：仿真时间、节点数量、移动速度、数据包大小及1丫rL值等链路特性是影响机会网络性能的重要参数，文章通过对现有典型路由协议的仿真分析，比较了在现实环境中链路因素对机会网络性能——投递率的影响。在ONE（The Opportunistic Network Environment Simulator）下的仿真结果表明，对于不同的路由协议，链路特性对消息投递率有不同程度的影响作用。Wireless link characteristics such as simulation time, the number of mobile nodes, the speed of mob- ility, packet size and TTL （ time to tive） value have important influence on the performance of opportunistic net- works. Through the simulation analysis of the existing typical routing protocols, the influence of link factor on delivery ratio, which is an important factor of link characteristic in the real opportunistic networks, is compared. By means of the ONE （the Opportunistic Networks Environment Simulator） , the simulation results show that different wireless link characteristics influence the message delivery to different degree ratio for different routing protocols.
