| 摘 要： | 在由以公共交通系统中的车辆为节点构成的无线网络中,由于其中节点的高速移动造成拓扑的快速变化,网络连接也多以瞬时的短暂连接为主.这构成了时延容忍网络(delay tolerant networks,DTN)的一个典型应用场景.公交节点的特性决定了其移动方式(时间、路线)带有一定的规律性.基于这一特性,构建了一种抽象的网络拓扑模型,并基于该模型提出了一种基于索引的多级分组路由算法.实验证明,基于预先的分组信息,该路由算法应用于高速移动的公交时延容忍网络中将比其他DTN路由更加的高效.

| Abstract: | In the wireless networks which consist of vehicles of the public transportation system,the topology changes rapidly and the links between nodes connect intermittently due to the high mobility.It is a classic application scenario of delay tolerant networks(DTN).The characteristic of node in the public transportation system determines that its mobility(such as time and path)follows a special rule.Based on this characteristic,an abstract topology of DTN is presented and a new communication efficiency weight is... |
