VANET is filed of networking that has been widely used in intelligent transportation system. VANET is an extension of MANET that is accessible for auto driven vehicle system. Various types of messages have been transmitted over the VANET for different purposes using various routing protocols. In this paper a literature study has been done about various approaches of video message transmission o...

Recent advances in development of Wireless Communication in Vehicular Adhoc Network (VANET) has provided Emerging platform for researchers. VANET are movable & fixed infrastructure. One of the main challenges in VANET is to secure communication. VANET is a open network for all and different types of attacker available for attack to victims node in the network & create problem in communication. ...

Group key management plays an important role in ensuring the safety and reliability of the VANET (vehicular ad-hoc network) over the channel. Through considering the characteristics of VANET communication and topology, a VANET group key management scheme is proposed based on random transmission which is combined with the construction of polynomial and key updating by Hash chain. The scheme achi...

In Intelligent Transport Systems (ITS), Vehicular Ad-hoc Network (VANET) is one of key wireless technologies, which helps in managing road safety, traffic efficiency, fleet, logistics and transportation. The objective of this paper is to give an overview of the implication of different technologies and placement of VANET in transportation and specifically in logistics. We provide researchers wi...

The Quality of Service (QoS) provides a better performance in networking environment like MANET and VANET in the current development scenario. In these fields the topology is dynamic in nature changing frequently with respect to time. Thus it creates many challenging issues too. In this paper, we have investigated the performance of MANET and VANET based on QoS, where throughput is taken as the...

Majority of characterization studies on Vehicular Ad Hoc Network (VANET) are based on simulations that assume little network errors and consistent signal strength. Existing VANET experiments, on the other hand, focus mostly on single-hop communication and they are conducted with external antennas or other built-in equipments in small areas. This thesis surveys the challenges in VANET and conduc...

Vehicular Ad Hoc Networks (VANET) are unique in their characteristics. Most of the VANET applications request one-to-many (group) communications. In this paper we discuss routing in DTN based VANET application. In our study we consider only the non-safety applications in the VANET environment. These applications request multicast routing. However the existing routing approaches which are mainly...

Clustering in vehicular ad hoc networks (VANET) is one of the control schemes used to make VANET global topology less dynamic. Many of the VANET clustering algorithms are derived from mobile ad hoc networks (MANET). However, VANET nodes are characterized by their high mobility, and the existence of VANET nodes in the same geographic proximity does not mean that they exhibit the same mobility pa...

. Abstract— Vehicles in a highway are connected to form a vehicular adhoc networks. (VANET) A VANET turns every participating vehicle into a wireless router or node. 100 to 300 meter distance is allowed between vehicles to cover a wide network range. In VANET network topology is rapidly changed due to high mobility of nodes. VANET uses infrastructure support to handle time sensitive data exchan...
