| 摘要: |
| 针对于数据报文在节点高速移动和链路部分连通的车载自组织网络中的传输问题,提出一种基于链路感知的路由协议LALO,该协议使用信标探测机制感知报文存储车辆节点周遭链路信息,以此为根据预测传输路径性能并决定报文的转发决策.模拟仿真结果表明,LALO路由协议具有报文成功传输率高,协议控制开销小,传输范围大等优点. |

| Abstract: |
| Due to high mobility and sparse distribution of vehicle nodes,data packets transmission in VANET face great challenges.To address the problem,this paper proposes a link-ware routing protocol named as LALO. The study first introduces a distributed beacon detection scheme to gather local traffic statistics,so vehicle nodes storing packets can predict performance matrix of transmission paths and decide which path is the optimal one to choose.Results show that the proposed LALO protocol outperforms existing solutions in terms of packet delivery ratio,protocol overhead and transmission range. |
