基于4G辅助的车载网地理路由算法
4G?based assisted geographic routing algorithm for VANETs
摘要
Abstract
An LTE and VANETs based geographic routing(LTE?GR)is proposed to solve the routing problem of VANETs urban scene,which makes full use of the characteristics of LTE high peak rate and low delay to assist the data transmission among VANETs. The eNodeB can collect the information of road segment,and compute the stability value of road segment to compare it with threshold. When the stability value is lower than the threshold,the data packet is forwarded with eNodeB. Other?wise,the data packet is transmitted with greedy forwarding geographic routing. The simulation results show that,in comparison with similar routings,the LTE?GR can improve the data packet transmission rate and end?to?end transmission delay.关键词
