摘　　要：针对车联网的资源共享问题进行研究,提出一种有效的资源共享方法ERS。ERS的目标是提高资源共享的成功率、减小资源共享的延迟和通信代价,以及提高发送效率。为了实现这些目标,ERS设计了查询、回复、资源的替换、收到资源的告知四个策略。基于真实的车辆行驶数据进行了仿真实验,仿真实验结果表明,相比其他两种方法,ERS实现较高的资源共享成功率、较低的延迟及通信代价和较高的发送效率,因此是车联网中一种有效的资源共享方法。This paper investigated the problem of resource sharing in Internet of vehicles, and proposed an efficient resource sharing method called ERS. The goal of ERS was to improve the successful ratio of resource sharing, to reduce the latency of resource sharing and communication cost, and to improve the transmission efficiency. In order to achieve these goals, ERS designed four strategies, including query strategy, reply strategy, resource replacement strategy, and acknowledgement strategy. This paper conducted the simulation experiment based on the real traces of vehicles. Performance results demonstrate that compared with the other two methods, ERS can achieve higher successful ratio of resource sharing, lower latency, lower communication cost, and higher transmission efficiency. Therefore, ERS is an efficient resource sharing method in Internet of vehicles.
