Abstract
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.
Highlights
The wireless communication in the proposed system is categorized into two kinds of communication: control plane and data plane
This implies that the hybrid routing strategy we employ to transfer data with OLSR uses less bandwidth than standard Open Flow-only routing, which is utilized to share data between the SDN controller and suitable fog router
Our findings indicate that when many wireless hops are available in a fog network, our traffic engineering strategy is successful in diverting packets to the new chosen path
Summary
The wireless communication in the proposed system is categorized into two kinds of communication: control plane and data plane. A data plane link connects the control plane to the flow policy rules during data transmission. An abstract policy labeled Policy Rules will be communicated by the SDN Controller, in which the RSUCs or BSs will use their local expertise to decide specific behavior. A link layer mechanism in every automobile can be used to frequently broadcast warning messages to gather information about neighbors in order to maintain an up-to-date vehicle network topology. When available, this information is delivered to RSU or BS, along with vehicle traffic data including a road map, position, speed, and sensor data [4, 5].
