Abstract: Vehicular networks use roadside infrastructures, roadside units (RSUs) and high-power nodes (HPNs), as fog nodes (FNs) in intelligent transport systems (ITSs). However, blending fog computing (FC) in ITS can stimulate the network with latency-sensitive applications, such as self-driving, augmented reality assistance and navigation. FNs assign resource blocks (RBs) to vehicles to furnish the services. However, as the vehicles that reach the network grow, FNs' energy consumption increases. Consequently, FNs become ineffective in delivering services. Therefore, to handle this issue, we present an energy-efficient resource allocation (EERA) algorithm to harmonise RB allocation among FNs, such that the energy utilisation of FNs is reduced. EERA algorithm relocates the assigned RBs of vehicles in overlap coverage amid pairs of FNs, such that the allocated RBs of FNs are minimised. The simulation outcomes show that the proposed algorithm minimises the energy consumption of FNs up to 42.5% on average compared to the existing algorithms.
