基于链路连通时间动态组网的AODV路由协议
AODV Routing Protocol Based on Link Connection Time Dynamic Networking
摘要
Abstract
An improved ad-hoc on-demand distance vector(AODV)routing protocol based on link connection time dynamic networking was proposed to solve the problems of unstable network topology and broadcast flooding when a large number of intelligent on-board units in the Internet of Vehicles transmit data.In the dynamic networking stage,cluster head selection and cluster maintenance were carried out by adopting dynamic networking algorithms based on minimum ID,minimum speed,and link connection time,respectively.Simulation results demonstrate that the cluster head changes the least and cluster stability is the strongest under the dynamic networking algorithm based on link connection time.Therefore,in the rout-ing stage,the dynamic networking algorithm based on link connection time was employed to improve the AODV route discovery process and alleviate the network congestion caused by communication among large numbers of vehicle nodes.Simulation and comparative analysis of the 5G NR-V2X network environment under the Veins architecture show that the AODV routing protocol based on link connection time dynamic networking performs well in reducing average end-to-end delay and improving the packet delivery rate.关键词
