| 摘 要： | 针对城市车载自组网具有路径寿命短、网络非连通的特点，设计一个低时延路由协议。该协议根据车辆密度建立时延模型，将路由分为路段转发和路口转发2个阶段，路口转发选择时延最小的路径进行路由。实验结果表明，该协议能在城市非连通的车载自组网中达到较高的分组投递率和较低的传输时延。

| Abstract: | For the characteristics of short path life and network disconnection in Vehicular Ad-hoc NETwork(VANET), this paper designs a low latency routing protocol. This protocol sets up a delay model based on vehicle density, divides the routing into two parts of road routing and intersection routing. The protocol chooses minimum delay path to forward in intersection routing. Experimental results show that this protocol can reach high group delivery ratio and low transmission delay in city disconnected VANET. |
