Abstract

The invention discloses a method and device for deploying and scheduling roadside units in an urban vehicle network. The method for deploying and scheduling the roadside units in the urban vehicle network comprises the following steps that S1, a plurality of target intersections are selected within a target area range according to a preset priority of each intersection to deploy the multiple roadside units according to the multiple target intersections; S2, multiple hotspot areas in each preset time period are identified in the target area range according to adensity-based clustering algorithm; and S3, the roadside units within the hotspot areas are scheduled to work according to the multiple hotspot areas within each preset time period. According to the method for deploying and schedulingthe roadside units in the urban vehicle network, the working state and the dormant state of the roadside units can be adjusted and controlled within a specified time period without affecting connection and service quality, and the energy resource utilization rate of the vehicle network is increased.

Description

technical field [0001] The invention relates to the technical field of roadside unit deployment, in particular to a method and device for deploying and scheduling roadside units in an urban vehicle network. Background technique [0002] At present, most applications of urban vehicular networks require the continuity of vehicle communication connections. The communication range of roadside units is usually larger than that of vehicle nodes, so it can help vehicles achieve end-to-end connections. However, in order to realize the communication coverage of the whole area by roadside units, a large number of roadside units need to be deployed along the road. Too much energy. [0003] In related technologies, most studies on the deployment and scheduling of roadside units in urban vehicular networks focus on the cost of roadside unit deployment and the service quality of vehicle data requests. It is still a waste of resources to be in the working state without participating in t...
