摘要:

为了解决城市道路多十字路口,对单个车辆节点运动感知不敏感所带来的通信性能下降问题,提出一种车载自组织网络中基于十字路口的地理感知路由(IGPR)协议,通过网络网关选择道路十字路口,形成骨干路由,在保证高连通概率的同时满足时延和误比特率要求。在双向道路模型的基础上分析获得平均时延和平均跳数的数学计算式。仿真结果表明,IGPR协议与FRGR协议、VRR协议相比,传输时延小,跳数少,通信性能好。

关键词: 车载自组织网络, 路由协议, 平均时延, 平均跳数

Abstract:

In order to solve the problem of the communication performance of degradation,which caused by multi-intersections in city environment and no sensitivity to individual node movements,an intersection-based geographical perception routing protocol in vehicular Ad Hoc network was proposed.The network gateways select road intersections to form the backbone of the route,ensuring a high probability of communication and meeting delay and bit error rate requirements.Mathematical formula of the average delay and the average number of hops were obtained on the basis of a two-way road model.Simulation results show that the transmission delay of IGPR is smaller,the number of hops of IGPR is less,and the communication performance of IGPR is better compared with the FRGR protocols and VRR protocols.

Key words: vehicular Ad Hoc network, routing protocol, average delay, average number of hops
