Assessment of Available Edge Computing Resources in SDN-VANETs by a Fuzzy-Based System Considering Trustworthiness as a New Parameter

In this paper, we propose a fuzzy-based system to determine the processing capability of neighboring vehicles in Software Defined Vehicular Ad hoc Networks (SDN-VANETs) considering vehicle trustworthiness as a new parameter. The computational, networking and storage resources of vehicles comprise the Edge Computing resources in a layered Cloud-Fog-Edge architecture. A vehicle which needs additional resources to complete certain tasks and process various data can use the resources of the neighboring vehicles if requirements to realize such operations are fulfilled. We propose a new fuzzy-based system to assess the processing capability of each neighbor and based on the final value, we can determine whether the edge layer can be used by the vehicles in need. The proposed system takes into consideration the available resources of the neighbors, their trustworthiness value and the predicted contact duration between them and the vehicle. Our system takes also into account the neighbors willingness to share their resources and determines the processing capability for each neighbor. We evaluate the system by computer simulations. Helpful neighbors are the trustworthy ones that are predicted to be within the vehicle communication range for a while and have medium/large amount of available resources.
