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

VANET routing has become a very popular area of research as it lays the foundation for the intelligent transportation system (ITS). 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 dynamics and affecting the network quality of Service (QoS). To improve the VANETs' QoS in dynamic scenarios, an efficient routing protocol is designed and implemented. Here, VANET-generated packets are routed to the destination through the Onboard unit (OBU) of vehicles and roadside units (RSU). The simulation results using MATLAB 2022a demonstrate that end-to-end delay is 0.106s and packet lost ratio is 5.91 for the proposed algorithm indicating our proposed algorithm performs better than the protocols like EERM, MAODV, and SDIoV. Simulation results show that the proposed protocol outperforms over previous algorithms in terms of QoS metrics e.g., packet delivery ratio (PDR), normalized routing load (NRL), energy usage (EU), and throughput.
