OLSR Protocol based on Fog Computing and SDN in VANet

Wireless technology has been the subject of a lot of study in recent years. VANET is the fastest-growing area in wireless communications. The Vehicle Ad-Hoc Network (VANet) is a subtype of the Mobile Ad-Hoc Network (MANet) that is used to enhance road safety and passenger experience, giving a unique perspective on intelligent transportation systems. This wireless invention is supposed to improve road safety and efficiency as part of the Intelligent Transportation System. Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) techniques that enable IEEE 802.11p wireless access technologies deliver applications (secure/unsecure) while exchanging information to avert an accident and provide travelers with trustworthy information make up the VANET. As an end result of investments in independent cars, new network technology including SDN, side computing, and VANET studies are being introduced, causing VANET simulators to review their assist for those new capabilities. In this paper, we offer an SDN-compliant solution for managing wireless fog networks by combining open Flow and IP transfer protocols in a way that provides a flexible and configurable wireless data plane for fog networks in addition intelligent traffic engineering for network offloading. The proposal includes an efficiency rating for connections with decreased latency, flexible load balancing to select the quickest way, and lower network cost.
