基于自适应选路策略的VANETs路由协议
VANETs ROUTING PROTOCOL BASED ON ADAPTIVE ROUTING STRATEGY
摘要
Abstract
Based on the characteristics of VANET, we present a VANETs routing protocol named as ASVP, which is based on adaptive routing strategy. Aiming at the frequent interruption property of link in VANETs, the carry-forward mechanism is introduced to protocol to make it be able to adapt to the intermittent connected delay tolerant networks. Through analysing and calculating the road model, we get the connectivity metric index of road sections, which is used to select the optimal route. Based on the road topology, the protocol divides the process of information transmission into straight mode and intersection mode, and the comparative analysis is made on boundary mode of VANETs for whether necessary or not; the auxiliary facilities will be used in intersection mode to forward the packets. Simulation results show that ASVP has certain advantages in delay and delivery rate in its application in urban scene.关键词
