Design and Implementation of a Routing Protocol for VANET to Improve the QoS of the Network

Abstract

Wireless communication Technology is very fast emerging for deploying and developing new as well as traditional applications. Most people are doing research on the Internet of Vehicles (IoV). Vehicular ad hoc Network (VANET) is a part of IoV, It scopes to reach internet access to make use of the available service on the road along with the improvement in safety, convenience and comfort or even entertainment. While travelling has become a very popular area of research as it lay the foundation for the intelligent transportation system. In VANET, the mobility of the vehicle is high hence the network is dynamic. Therefore, the connectivity between the two vehicles and the roadside unit (RSU) keeps changing, increasing the links and reducing the network quality of Service (QoS).In this context, a more effective routing protocol is needed that would be improved the VANET quality of Service (QoS). In this paper, a routing protocol is designed and implemented to improve the QoS of the VANET network. Here the VANET packet is routed to the destination using multiple Onboard unit (OBU) of vehicles and roadside units (RSU). The proposed process is simulated using MATLAB 2022a and shows the performance of the improvement of QoS parameters like end-to-end delay, packet delivery ratio (PDR), normalized routing load (NRL), energy usage (EU) and throughput is better than the previously implemented routing protocol such as SDIoV (SDN Enabled Routing for Internet of Vehicles), and well-known protocol AODV.
