摘要：

在车载自组织网络中,由于车辆的高速移动性、速度及位置分布不规则等因素,易导致通信链路断开。为此,在分析总结车辆行驶特点的基础上,提出一种基于链路可靠性的路由优化方案,通过划分稳定通信距离、计算可用连接时间与创建最大链路重置处理机制,达到优化链路可靠性的目的。实验结果表明,与AODV及其他相关方案相比,该方案在提高链路可靠性和数据的传递效率以及降低链路断开次数等方面具有较好的效果。

Abstract:

Communication links are easily affected by speed and irregular location distribution due to high-speed movement of cars in Vehicular Ad hoc Network(VANET).A routing optimization scheme based on link reliability is proposed after analyzing the characteristic of car driving.Links reliability optimization is realized by dividing stable communication distance,calculating available connecting time and the handling mechanism of max multiple value of links.Experimental results show that,compared with AODV and other schemes,this scheme has a better performance on link reliability,data transport efficiency and the disconnecting number of link.

Key words: Vehicular Ad hoc Network(VANET), communication distance, link reliability, routing scheme, connecting time
