Abstract
Vehicular Ad-Hoc Network (VANET), a subset of Mobile Ad-Hoc Network (MANET), enables intelligent communication, secure data transmission, and efficient
traffic management among vehicles. It facilitates wireless communication between vehicles and roadside units (RSUs) to enhance safety in urban areas by reducing accidents. VANET utilizes Wi-Fi and WiMAX technologies for vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) interactions. The increasing number of cars on the road has heightened the need for a better traffic system. However, designing effective routing protocols for VANET is challenging due to node speed and dynamic network changes. Routing protocols aim to facilitate data exchange between vehicles and between vehicles and infrastructure. Researchers are actively exploring new protocols tailored to diverse traffic scenarios. The integration of electric vehicles (EVs) into intelligent transportation systems (ITS) has led to the proposal of an EV charging station management scheme, evaluated using VANET protocols. Position-based protocols like MDORA, GRP, and G-MDORA play a crucial role. By extracting node coordinates using GPS, these protocols enhance algorithm efficiency. This research focuses on simulating the MDORA protocol in various scenarios, including a city-like environment and modifications like MDORA-OD and MDORA-WD. A comparison is
made in V2V communication, highlighting MDORA-WD's superior performance. Furthermore, the study simulates the GRP protocol in a city-like environment and compares its performance with MDORA in V2V communication. The comparison reveals that GRP has the lowest OH and highest PDR, while MDORA has a slightly lower E2E delay. A proposed algorithm, G-MDORA, combines the advantages of MDORA and GRP and the protocols are compared. The results indicate that G MDORA performs best regarding E2E delay, OH, packet loss ratio (PLR), and throughput of MDORA and GRP protocols, while GRP has a higher rate in terms of PDR. The protocols are further modified for V2I communication, and the protocols have been compared. The results show that G-MDORA has the least delay and OH, along with the highest throughput, while GRP exhibits a higher PDR rate. Finally, a scheme for managing EV charging stations is presented, based on communication between EVs and RSUs. The performance evaluation, using G-MDORA, GRP, and MDORA, assesses E2E delay, OH, PDR, and throughput. The comparison results demonstrate that G-MDORA performs the best in terms of throughput, with the least delay and OH, while GRP has a higher PDR rate
