| 摘 要： | 动态寻路（Dynamic Routing）是一项用以解决城市交通拥堵的智能交通技术.通过让一些车辆产生和转发路况拥堵消息,另一些车辆能够避开拥堵路段,从而缓解交通状况.以“存储-携带-转发”为通信模式的机会网络被广泛运用于动态寻路研究.文中提出了一种新型路况信息的机会转发算法,算法综合考虑车辆的位置和行驶方向.仿真实验表明,算法在保持信息散布效果的前提下,显著降低了网络负载,提升了效率.

| Abstract: | Dynamic Routing is an intelligent transport technology, aiming at the solution of urban traffic congestion. In this model, some vehicles originate and spray road congestion message while others receive them and may avoid the congested road. Opportunistic routing, featured by＂ store-carry-forward＂ communication mode, is widely applied in the study of dynamic routing. This paper proposes a new opportunistic dissemination model for spraying messages in dynam- ic routing. The model makes an integrated consideration of vehicles locations and directions. Simulation indicates that the proposed dissemination model could maintain highly-effective delivery ratio while remarkably reducing the network load. And thus a high forward efficiency is achieved. |
