Vehicular Ad Hoc Networks (VANETs) or Inter-Vehicle Communication (IVC) is an extension to a popular Mobile Ad Hoc Networks (MANETs) technology. VANET is developed to provide comfort communication between the vehicle while driving. In VANET there is a continuous wireless data transmission occurs either between Road Side Units (RSUs) or On Board Units (OBUs) in the vehicles. To keep the transmission smooth it required a good routing protocol. Right from the inception of VANET technology in 2000s the work done only on basic routing protocol. Mobility model is one of the key parameter while designing the vehicular network. In this paper the Simulation of Urban Mobility (SUMO) and Mobility Model Generator for VANET (MOVE) are used for creating scenarios and traffic. The real time maps are edited in JAVA open street map editor (JOSM) and the simulation is done in NS-2. The performance is evaluated by using the two routing protocol on the basic of packet delivery ratio and end to end delay for Urban scenarios.

Congestion problem and packet delivery related issues in the vehicular ad hoc network environment is a widely researched problem in recent years. Many network designers utilize various algorithms for the design of ad hoc networks and compare their results with the existing approaches. The design of efficient network protocol is a major challenge in vehicular ad hoc network which utilizes the value of GPS and other parameters associated with the vehicles. In this paper GPSR protocol is improved and compared with the existing GPSR protocol and AODV protocol on the basis of various performance parameters like throughput of the network, delay and packet delivery ratio. The results also validate the performance of the proposed approach.

In today's world, VANET (Vehicular Adhoc Network) plays a very important role and used for public safety communications and commercial applications. The most challenging task for VANET is Routing Algorithm due to rapidly changing topology and high speed mobility of vehicles. In this paper, we study the performance of modified Edge Based Greedy Routing Algorithm. In this algorithm, we set RSU's to provide better communication and improving performance of the movement of the vehicles and packet forwarding. The RSU at different Transmission Range are able to communicate with other RSUs and vehicles.

IAEME PUBLICATION, 2020
Vehicular Ad-hoc Network (VANET) is a boundless and emerging area of research in vehicular communication technology. It is mostly utilized in safety applications and to give ease during driving. VANETs connect the vehicles and the infrastructure to share data securely during traveling on highways(urban), or interlinked roads(rural). In VANETs, all mobile nodes can move unrestrictedly in the network and can communicate with any of the nodes in the network. It is one of the foundational technology used for the safe, efficient, and entertaining transportation system. A notable time is spent by people in communicating through vehicles. To make their trip more secure and less time-consuming smart vehicles based on VANETs have emerged. To leverage the maximum benefit of VANETs, the routing protocols play a vital role. Researchers have developed applications using AODV, DSDV, DSR, and other routing protocols to manage heavy and unruly traffic. In this paper, these protocols are studied and compared based on different attributes such as recovery strategy, type of environment, traffic flow, and so on. Further, the protocols under bio-inspired algorithms were studied.
A Review of Various Routing Protocols in VANET
International Journal of Advanced Engineering Research and Science
Vehicular Ad-hoc Network (VANET) is a self-organized network that connects vehicle and RSUs. The RSUs can intern be connect to a background network so that many other network applications and services including internet access can be provide to the vehicle for obtaining different services by the user or driver. The considerable attention goes in this field due to the high demands of new innovations in the vehicular industry. The primary purpose of VANET is to improve public safety and save lives as well as to improve vehicular traffic flow. VANET has very dynamic topology large network size and constrained mobility, these characteristic led to the need for efficient routing and resource saving protocol. It is a new research area which tends lots of emphasis towards services provided through the network. In this paper, we give the review of various routing protocols by using some parameters: digital map, scenario, position verification, clustering, routing mechanism, forwarding strategy and control overhead.
