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.
