基于道路分段的车载自组织网络路由协议
Vehicular Ad Hoc Network Routing Protocol Based on Road-subsection
摘要
Abstract
Aiming at the problem of unstable routing links caused by rapid vehicle movement and frequent changes of network topology in urban Vehicular Ad Hoc Network (VANET), an vehicular routing protocol RSRP (Road-subsection Routing Protocol) based on road subsection is proposed. This paper takes into account the impact of traffic lights on the speed and spatial distribution of vehicles and segments the roads. On this basis, the selection of backbone nodes is selected on the road, a stable road backbone network is established bridge nodes is selected at the intersection, these nodes are connected with backbone node on adjacent sections of the road, the transmission delay packet generated is gotten, and the information of network topology is updated on the road. Through the vehicle state information obtained by the bridge node, the section is distributed the corresponding weights, and the corresponding minimum weight is selected as sections of the routing path, to improve the delivery rate of data packet transmission and reduce the End to End Delay (E2ED).The real urban road and vehicle traffic scenarios are simulated under the NS2 experimental simulation platform, results show that the RSRP protocol can be better applied to urban road scenarios than GPSR and GyTAR routing protocols.关键词
