Vehicular Ad Hoc Network (VANET) is the subgroup of the Mobile Ad Hoc Network (MANET). VANET interconnects the nodes for transferring secure information between nodes, here vehicle acts as a node. VANET is used to provide safety and efficiency in transportation system. Many traffic signals are used to reduce accidents in the roads, but since it is not much effective. Hence VANET is used; it use...

VANET (Vehicular Ad Hoc Network) is actually an important field for the development of a variety of services. In VANET charging and billing of services could not be enabled in the same way as in classical mobile and fix networks and MANET (Mobile Ad Hoc Network) because of the characteristics of such network namely the high speed of nodes, frequent disconnection between nodes, rapidly changing ...

Broadcasting is the process of sending a message from one node to all other nodes in an ad hoc network. It is a fundamental operation for communication in ad hoc networks as it allows for the update of network information, route discovery and other operations as well. In this paper, we review the pros and cons of different broadcasting methods in VANET. Also, the broadcast storm problem and bro...

VANET is a vehicular ad hoc network where a shortlived network is formed among the VANET nodes. VANET nodes communicate and interchange messages with other vehicular nodes either in an infrastructure or infrastructure-less network. Due to lack of fixed infrastructure, VANET is prone to varied attacks. In impersonation attack, identity of the legitimate node is stolen by an attacker. In this pap...

Vehicular Ad hoc Networks (VANET) exhibit highly dynamic behaviour with high mobility and random network topologies. The performance of Transmission Control Protocols (TCP) on such wireless ad hoc networks is plagued by a number of problems: link failures, scalability, multi-hop data transmission and data loss. In this work, we make use of the vehicle’s movement pattern, density, velocity and v...

Vehicular Ad-hoc network (VANET) is prominent research area in Mobile ad-hoc network (MANET). VANET are very dynamic in nature as it has no predefined structure for communication. The performance of VANET dependents on parameter configuration of the protocol used in. The optimal parameter configuration in protocol can improve the QoS of VANET. Further, finding the optimal values of the paramete...

Vehicular Ad hoc Network (Vanet) is one of the emerging technologies to support safety, traffic monitoring and comfort related services. Vanet is a subclass of MANET but its topology changes rapidly and network gets disconnected frequently. The prevailing routing protocol of MANET is very much applicable to Vanet. Because of its frequently disconnecting routes it is difficult to design an effic...

VANET is the technology of building a robust Ad-Hoc network between mobile vehicles and each other, besides, between mobile vehicles and roadside units. Throughout the world, there are many national and international projects in governments, industry, and academia devoted to the development of VANET protocols. In this paper I have reviewed the various security protocols used for vehicular ad ho...

The performance of VANET remains optimum within thousand meters and after that due to high packet loss rate communication among vehicles is not feasible. Finding optimal path is a typical task for dynamic protocols. The research objective is to study some of the important QOS metrics in VANET & vehicular traffic management solutions to improve overall safety of traffic. Keywords— Vehicular Ad h...
