- 摘要:
- 随着经济水平的快速发展,车辆越来越多。车辆的增多给道路带来如交通拥塞和交通安全等问题。为这些信息提供服务质量保障将提高交通安全并提升用户的乘车体验。基于增强分布式信道访问机制提出了一个新的服务质量保障方案——scenes enhanced distributed channel access(SEDCA)。通过边缘服务器获得道路密度,并在接入类别队列内部根据信息属性设计了分类器来更加严格的区分消息的优先级。然后,在不同场景下,从接入类别队列内部调度、增强分布式信道访问参数调整等方面对信息提升服务质量性能。仿真结果表明方案提升了网络性能。
- Abstract:
- With the rapid development of the economic, there are more and more vehicles. The increase in vehicles brings problems such as traffic congestion and traffic safety to the road. Providing quality of service for the information will improve traffic safety and enhance the user's ride experience. Based on the enhanced distributed channel ccess(EDCA)mechanism, we propose a service quality assurance scheme, called scenes enhanced distributed channel access(SEDCA). We obtain road density through the Mobile omputing Edge(MEC)Server, and design a classifier based on information attributes within the Access Category(AC)queue to more strictly distinguish the priority of the message. Then, in ifferent scenarios, the information is differentiated from the internal scheduling of the AC queue, and the EDCA parameters adjustment to improve the QoS performance. Simulation results show that our solution improves network performance.
