Vehicular ad hoc network (VANET) can offer various services and benefits to VANET users and thus deserves deployment effort. Misusing such network could cause destructive consequences. It is therefore necessary to discourage misbehavior and defend VANET systems against it, in order to ensure correct and smooth operations of the network. In this paper, we review the techniques for handling misbe...

Vehicular Ad Hoc Networks (VANET) has great potential to improve road safety and increase passenger convenience in vehicles. On the other hand, since they use an open medium for communication, they are exposed to several threats that influence the reliability of these features. The need for a robust VANET networks is strongly dependent on their security and privacy features, which will be discu...

Large scale node to node systems face security threats from malfunction or hostile remote computing elements. Node to node system commonly relies on the existence of multiple independent remote entities to mitigate the threat of hostile nodes. Sometime single faulty node can produce various identities leading to control of substantial fraction of the system. These attacks are called Sybil attac...

Vehicular Ad hoc Network (VANET) is a wireless network that is formed on the fly between a collection of cars connected by wireless links. VANET has gained a great amount of attention during recent years and is used for a large number of safety (accident warning, weather notification) and non-safety (multimedia, gaming) applications. Vehicular Network is one of the most growing type of wireless...

Vehicular ad hoc networks (VANETs) are essential components of a smart city environment owing to some safety-enhancing applications. The use VANETs extends from safety applications such as accident warning and collision avoidance entertainment streaming video or comfort parking spot identification. Besides, these require interconnecting, for example, by enabling vehicles communicate with other ...

Large variations in network Quality of Service (QoS) such as bandwidth, latency, jitter, and reliability may occur during media transfer over vehicular ad hoc networks (VANET). Usage of VANET over mobile and wireless computing applications experience “bursty” QoS behavior during the execution over distributed network scenarios. Applications such as streaming media services need to adapt their f...

Being foreseen its promise of plethora of applications, Vehicle Ad hoc NETwork (VANET) has become an important research topic. Among many challenging issues, robust message dissemination is one of the indispensable requirements for various VANET applications, which affects the message delivery ratio, transmission delay and packet communication overhead. In this paper, we first systematically an...

Vehicular Ad hoc Networks (VANETs) is usually grouped with other similar networks types such as Mobile Ad hoc Networks (MANETs) and Wireless Mesh Networks (WMN). All of these types of networks are characterized as self-configuring and infrastructure-less. However, the vehicular nodes in a VANET are highly mobile and the corresponding communication protocols are specified to work up to speeds of...

VANET are considered to be the special application of infrastructure-less wireless Mobile ad-hoc network (MANET). In these networks, vehicles are used as nodes. Recently Many researches has been done on this topic as a proof of which US government has recently granted permission for vehicle to vehicle communication accepting that it will be very helpful for minimizing road accidents which costs...

All automobile manufacturers continue to incorporate more and more technological features into their vehicles. One of the features is wireless access. A Vehicular Ad-Hoc Network or VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network. VANET turns every participating vehicle into a wireless router or node. Some measurement studies have previously been ...
