摘要 该文针对车联网移动边缘计算环境下,车辆在快速移动和切换时与多个边缘服务器间的任务卸载协商所面临的安全性能和系统能耗问题,提出了一个基于边缘服务器和车载服务器协同工作的任务卸载策略安全协商机制,描述了车辆移动时的安全切换交互协议,讨论了其基于边缘服务器覆盖范围的任务分配协商算法及其约束条件。仿真结果表明:该方案可以有效保证通信时的安全性能,同时其卸载能耗及卸载时间与现有方案相比分别减少了58%和17%。

Abstract:Task offloading negotiations between vehicles and multiple edge servers in mobile edge computing environments of the internet of vehicles have security problems and excessive system energy consumption. This paper presents a security offloading mechanism based on cooperation between the edge server task offload strategy and the vehicle server. The strategy has a secure switching interaction protocol when the vehicle is moving with a task assignment negotiation algorithm and constraints based on the edge server coverage. Simulations show that the scheme effectively guarantees security during communications while reducing the offloading energy consumption by 58% and the offloading time by 17% compared with an existing scheme.
