With the development of the vehicular network, BusNet-based service is of great interest to both bus companies and public users. How to provide service and ensure service quality is considered as key points for the promotion of such kinds of applications. In this paper, a system architecture, which is designed based on multiaccess edge computing (MEC) architecture and software-defined network (SDN), is proposed. Moreover, considering the problem of the dynamicity of the network, a new routing path optimization algorithm, SPSO (serial particle swarm optimization), is proposed, while a dynamic weight matrix is used to improve routing performance. The comprehensive simulation results demonstrate that the proposed method can well adapt to the dynamic change of network topology and improve communication performance significantly.

软件定义的BusNet中面向车辆服务的动态路由搜索算法

随着车载网络的发展，基于BusNet的服务已引起公交公司和公共用户的极大兴趣。如何提供服务并确保服务质量被视为促进此类应用程序的关键点。提出了一种基于多访问边缘计算（MEC）架构和软件定义网络（SDN）设计的系统架构。此外，考虑到网络的动态性问题，提出了一种新的路由路径优化算法SPSO（串行粒子群优化），同时使用了动态权重矩阵来提高路由性能。综合仿真结果表明，该方法能够很好地适应网络拓扑的动态变化，并能显着提高通信性能。
