| 摘 要： | 针对机会网络在偏远地区应用的前景,构建一个类似偏远地区的应用环境,并分析机会网络中典型的路由协议,对典型路由协议在偏远地区的应用进行仿真。从传输成功率、路由开销、平均延时时间和平均缓存时间四个方面评估各路由协议在偏远地区应用的性能。仿真结果表明,Max Prop和Spray And Wait协议在该场景中表现出较好的性能;多副本的转发机制在传输成功率和传输延迟方面要优于单副本的转发机制;多跳的路由机制会增加网络的路由开销。

| Abstract: | Aiming at the future prospect of opportunity network in remote areas, the paper constructs an application environment similar to remote areas, analyzing the typical routing protocols of opportunity networks and emulating the application of the protocols in the network scenario. The functions of these routing protocols are evaluated in terms of delivery-prob, overhead-ratio, latency-avg and buffertime - avg. And the result indicates that Max- Prop and SparyandWait perform better in this scenario, the forwarding mechanism with multiple copies is superior to the one with single copy, and the multi hop routing mechanism will increase the routing overhead. |
