Vehicular Ad hoc Networks (VANET) is the subclass of Mobile Ad Hoc Networks (MANETs). It is the most advanced technology that provides Intelligent Transportation System (ITS) in wireless communication among vehicles to vehicles and road side equipment (RSUs) to vehicles according to IEEE 802.11p standard. VANET provides broad range of safety and non safety applications. Safety application provi...

Vehicular Ad-hoc Network (VANET) is an important component of intelligent transportation systems, in which vehicles are equipped with on-board communication devices which enable vehicle-to-vehicle communication. Consequently, with regard to larger communication due to the greater number of vehicles, stability of connectivity will be a challenging problem.Clustering technique as one of the most ...

VANET is a vehicular ad hoc network where a short-lived 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. As per pro...

Although inter-vehicle communications (IVC) technologies intend to improve driving safety and enable infotainment applications, empirical testing within large-scale deployments remains cost-prohibitive, thus highlighting the need for accurate simulation models. While using current models, simulation practitioners limit future extensions and produce inconsistent results by choosing different des...

Vehicular Ad Hoc Networks (VANET) is a very promising research venue that can offers many useful and critical applications including the safety applications. Most of these applications require that each vehicle knows precisely its current position in real time. GPS is the most common positioning technique for VANET. However, it is not accurate. Moreover, the GPS signals cannot be received in th...

Value-added applications in vehicular ad hoc network (VANET) come with the emergence of electronic trading. The restricted connectivity scenario in VANET, where the vehicle cannot communicate directly with the bank for ...

Vehicular Ad-hoc Network (VANET) is a growing technology. The vehicle (acting as mobile routers) in the network uses the wireless medium to communicate with other nodes (vehicles) in their radio range. A heterogeneous wireless network (HWN) which is hybrid network of cellular network (having access routers (AR) and Internet Service Providers (ISP) for providing communication and internet servic...

In this paper, the concept of VANET is discussed in detail. The different concepts used in VANET are explained with very good style. The applications of VANET are also discussed here. In the near future, most new vehicles will be equipped with short range radios capable of communicating with other vehicles or with highway infrastructure at distances of at least one kilometer. The radios will al...

Recently, a vehicular ad-hoc networks(VANETs) for Intelligent Transport System(ITS) have become able safety and convenience services surpassing the simple services such as an electronic toll collection system. To provide the proper services, VANET needs infrastructure over the country infrastructure. Thus, we have to spend a huge sum of human resources. In this reason, several studies have been...

Vehicular Ad Hoc Networks (VANET) is an emerging and promising technology, this technology is a fertile region for attackers, who will try to challenge the network with their malicious attacks. The security of VANET has mostly directed the attention of today research efforts, while comprehensive solutions to protect the network from adversary and attacks still need to be improved, trying to rea...
