Reliability and performance analysis of vehicular fog computing

Vehicular fog computing (VFC) is an advanced standard that utilizes one or more cooperative end-users or neighboring edge devices for communication, storage, configuration, control, management, and measurement operations. This paper studies the reliability of VFC which is explored as a function of its reliable hardware. The architecture of VFC is a multi-layered architecture, therefore composite modeling technique is adopted for the reliability study. Different models are constructed for each layer using reliability block diagrams, and then the models are integrated to obtain the reliability of the entire VFC network. Further, this paper analyses the performance of VFC and evaluates various measures such as end-to-end delay, throughput and utilization. A queueing network model depicting the message dissemination scheme in the network is proposed to evaluate the performance measures. Numerical results are also obtained to show the efficacy of the proposed models.
