摘要/Abstract

摘要：

车载边缘计算（vehicular edge computing，VEC）是一种可实现车联网低时延和高可靠性的关键技术。VEC可解决车载终端计算能力不足的问题，同时可减少车联网通信服务时延，避免路边停泊车辆自身大量空闲资源浪费。提出基于停泊车辆中继的车载任务卸载方案，通过合理部署边缘服务器和引入协作中继技术，可将车联网通信过程中的时延降低至毫秒级。仿真结果表明，与传统的车与基础设施（vehicle to infrastructure， V2I）卸载方案相比，基于停泊车辆中继的车载任务卸载方案可将通信时延降低20%。

关键词: 车辆边缘计算, 静态中继, 卸载方案

Abstract:

Vehicular edge computing (VEC) is a key technology that can realize low latency and high reliability in vehicular network.VEC can solve the problem of insufficient computing of vehicle terminals,and reduce the communication service delay of vehicular network,avoiding a large amount of waste of free resources in parked vehicles on the road.A task offloading scheme based on parked vehicles relay was proposed,which could reduce the delay in vehicles’ communication process into the millisecond level by rationally deploying the edge server and introducing the cooperative relay technology.Numerical results indicate that compared to direct V2I offloading model,the communication delay can be reduced by 20% in the parked vehicle relay transmission.

Key words: vehicular edge computing, static relay, offloading scheme
