Real-Time VANET Applications Using Fog Computing

Abstract

The main objective of vehicular ad hoc networks (VANETs) is to improve driver safety and traffic efficiency. Most of VANET applications are based on periodic exchange of safety messages between nearby vehicles and between vehicles and nearby road side communication units (e.g., traffic lights, roadside lights etc.). This periodic communication generates huge amount of data that have typical storage, computation, and communication resources needs. In recent years, there have been huge developments in automotive industry, computing, and communication technologies. This has led Vehicular Cloud Computing (VCC) as a solution to satisfy the requirements of VANETs such as computing, storage, and networking resources. Fog computing is a standard that comprehends cloud computing and related services to the proximity of a network. Since VANET applications have special mobility, low latency, and location awareness requirement. Fog computing plays a significant role in VANET applications and services. In this paper, we present real-time applications of VANET that can be implemented using fog computing.
