机会网络中基于城乡模型的多ferry路由设计

摘要

In order to press close to the practical application of the opportunistic networks, this paper proposed a city-village model. In order to decrease the averge delivery delay, based on the model, proposed the direct-ferry (DF) algorithm. The main idea of DF algorithm was to let ferries communicate with others directly by coordinating the movement of all ferries. It compared the average delivery delay of DF algorithm with the algorithm using relay nodes. The result shows that GF algorithm can decrease the average delivery delay of network effectively.%为更贴近机会网络的实际应用,提出了城乡模型.基于此模型,为了降低网络的平均传输时延,提出了DF (direct-ferry)算法.DF算法是通过调度所有ferry的运动来实现ferry之间的直接通信,从而实现网络的区间通信.通过DF算法和使用中继节点的ferry路由算法的对比,得出DF算法能够有效降低网络的平均传输时延.
