摘要
分析城市场景下路侧单元的节能问题。针对单个十字路口场景,两个路侧单元部署在该路口,覆盖整个十字路口区域,进入该十字路口的车辆节点均要接受两个路侧单元服务的情况。将路侧单元对重叠覆盖区域中的车辆进行服务分配,以达到降低两个路侧单元总能耗的目的。在分析建模的过程中,综合考虑车辆到达率、路侧单元服务率和路侧单元覆盖范围等因素。通过仿真实验,验证了该分配方案可以有效降低路侧单元的总消耗。
This paper studies the energy conservation of roadside side units under urban scenario.Considering a single intersection scenario,two RSUs are deployed to cover the entire intersection area.The vehicle nodes entering the intersection are served by the two RSUs.In order to reduce the total energy consumption of roadside units,the optimal service allocation policy for the two RSUs is built.In addition,factors such as vehicle arrival rate,RSU service rate and RSU coverage radius are also considered.Finally,the simulation results show that the proposed scheme can effectively reduce the total consumption of RSUs.
