车联网中基于组合权重的广播路由算法
A combinatorial weight-based broadcast routing algorithm for vehicle-to-vehicle communication
摘要
Abstract
Vehicle AD hoc Networks(VANETs),which have emerged with the development of the Inter-net of Things(IoT)and Intelligent Transportation Systems(ITS),are prone to network congestion and link instability due to the high mobility of vehicles.Introducing efficient routing technology between vehi-cles can reduce latency and enhance reliability.Since the high-speed movement of vehicle nodes can lead to rapid changes in the network topology,multiple parameters such as the position and speed of the vehi-cles,inter-vehicle distance and the direction of movement must be considered when choosing route weight factors.Aiming at the problems of low routing selection efficiency and unstable links,a broadcast routing selection algorithm based on combined weights is proposed.The algorithm selects the optimal path from the route established from the source node to the destination node based on the combination of four weigh-ting factors:inter-vehicle distance,angle of vehicles relative to the horizontal direction,link interruption rate,and traffic density.Simulation results show that,compared with the LSPR algorithm,the proposed TPWR algorithm increases the data transmission rate by 25.12%and the link lifetime by 17.68%.关键词
