A vehicular ad-hoc network (VANET) is an autonomous and self-configuring network of mobile hosts connected by wireless links. It is a highly dynamic network and has harsh channel conditions. Cluster-based MAC scheme in VANET is needed to overcome the lack of specialized hardware for infrastructure and the mobility to support network stability and channel utilization. This work presents a MAC al...

The prime goal of Vehicular Ad hoc Network (VANET) is to provide life safety on the road. To achieve this, vehicles make use of two types of safety messages one is Periodic safety messages (beacons) to exchange status information e.g. position, speed etc. and second one is Event-driven messages to broadcast in case of an emergency situations e.g. accidents, hardbraking etc. The main objective o...

VANET is an higher version of Mobile Ad-hoc Network (MANET). Which protocols used in the MANET are suitable to the VANET also. Many researchers are involved in VANET field, who can provide life safety and traffic management system. In continuous growth of the vehicular industry, designing and implementing VANET is a complex and wide area of research. Thus, As we all know that these studies and ...

In this paper we investigate the possibility of a new type of application, namely multiplayer games, in a Vehicular Ad Hoc Network (VANET) environment. First, we analyze the available empirical data on travel and traffic volume in the United States, and point out the most important challenges that have to be met in order to enable multiplayer games over VANET. We then propose a new paradigm of ...

Vehicular Ad Hoc Networks (VANETs) are a particular category of mobile ad hoc networks (MANETs) characterized by a high mobility and a reduced connectivity. In order to develop protocols for vehicular networks, the community may either create VANET specific approaches, or adapt already existing protocols to VANET. While the former may provide efficient specialized solutions, the latter offers a...

Vehicular ad hoc network (VANET) technology uses moving vehicles as nodes in a network to create a mobile network. 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 tim...

An Ad-hoc network has a Provision of Quality of Service(QoS) to support multimedia applications. One of the most challenging tasks in Ad-hoc Network(MANET &VANET) is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth and delay constraints, varying channel conditions, power limitations, node mobility,dynamic topology, packet delivery ratio, end-to-end delay and...

Vehicle Ad-hoc Network (VANET) is a kind of Mobile Ad-hoc Network (MANET) that establishes wireless connection between cars. In VANETs and MANETs, the topology of the network changes very often, therefore implementation of efficient routing protocols is very important problem. In MANETs, the Random Waypoint (RW) model is used as a simulation model for generating node mobility pattern. On the ot...

Abstract—VANET (Vehicular Ad Hoc Network) is an emerging technology to achieve intelligent inter vehicle communications, it is the specialized derivation of pure multi hop ad hoc networking and are already going through industrial prototyping; the dreamed idea of general purpose vehicular ad hoc network is still away from reality. Vehicular communication has been one of the hottest topics for t...
