基于车联网WAVE的多跳路由连接中断预测算法

当信息源车辆与信息目标车辆之间不能通过一跳来完成信息交互时,车辆间多跳路由连接的建立是保证车联网WAVE中信息源车辆和信息目标车辆之间能够进行信息传递的关键。通过研究和分析快速多跳路由算法FMHR得知,车联网中各节点车辆之间建立起来的多跳路由连接会因各节点车辆之间的速度不匹配而时常发生通信中断,针对这一问题,试着在原有算法中增加路由连接中断的预测方法,并使用支持IEEE 802.11p的开源软件NCTUns-6.0建立相关仿真实验,结果表明,增加路由连接中断的预测方法可改善车辆之间信息传递的效率。

Interrupt Prediction of Routing Connection based onWireless Access in Vehicular Environment

When information source vehicle and target vehicle could not implement direct message exchange, the establishment of inter-vehicle multi-hop routing would become the key to ensuring information exchange of between source vehicle and target vehicle. Research and analysis on HMHR(Fast Multi-Hop Routing) algorithm shows that frequent communication interrupt would usually happen between these vehicles due to their mismatching velocities. In order to solve this problem, the prediction method is tried to add in the original algorithm, and the related simulation experiment with open source tool NCTUns-6.0 which supports IEEE 802.11p,indicates that this prediction method could effectively improve the information transfer of between the vehicles.
