摘要:
移动伺机网络是延迟容忍网络,通信发生在移动节点间的接触机会,不需要建立终端到终端的消息路由路径。在移动机会网络中,节点合作是基本的消息传递过程。这样的网络由于频繁中断和延迟,以及间歇性的连接环境面临着诸多挑战。本文研究了由人携带的无线网络设备之间的消息的路由协议,并根据真实流动性数据进行评估和比较分析了直送,传染,随意,PRoPHET,链路状态,并及时通信的六种路由协议。

Abstract:
With more and more mobile devices are connected into the network, the mobile network presents the following features: intermittent connectivity is frequent and mobile nodes can communicate with each other even if a route connecting them did not previously exist. So the mobile opportunistic networks emerged. The communications in mobile opportunistic networks take place on the establishment of opportunistic contacts among mobile nodes, without availability of end-to-end message routing paths. To ensure source nodes connect with destination quickly and send message successfully in the mobile opportunistic networks, we studied six different routing protocols for transmitting message in the mobile opportunistic networks and took analysis about their advantages and disadvantages.
