The average energy efficiency of computation offloading in multi-access edge computing (MEC) enabled Internet-of-Vehicles (IoV) networks with wired backhaul links is investigated in this paper. Specifically, the cumulative distribution function (CDF) for computation delay over wired backhaul link is derived in closed-form. The average energy efficiency of computation offloading in MEC-enabled IoV networks with wired backhaul links is derived in closed-form, and is compared against non MEC-enabled IoV networks with wired backhaul links. Numerical and simulation results show that MEC-enabled IoV networks can attain at least 10 times higher energy efficiency than non MEC-enabled IoV networks. Furthermore, we show that energy efficiency can be maximized through the proper selection of task size and transmission deadline in the MEC-enabled IoV network.
