A vehicular ad hoc network (VANET) is a relatively new term for an old technology – a network that does not rely on pre-existing infrastructure. When integrated into the intelligent transportation systems (ITS), it can provide direct vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, thereby can greatly improve the safety and efficiency of road traffic. The emerging an...

In this demo we describe VIVAGr, a graphicaloriented real time visualization tool for vehicular ad-hoc network connectivity graphs. This tool enables the effective synthesis of structural, topological, and dynamic characteristics of VANET graphs, with a variety of parameters that affect the shape and characteristics of a vehicular ad hoc network. Keywordsreal-time graph visualization; VANETs; i...

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...

In recent days Inter-Vehicle communication has fascinated many research communities and automotive industries .With the introduction of inter-vehicle communication it would be possible for vehicles to communicate with each other and thus this functionality will provide intelligent transportation system as well as many assistant services for drivers and passengers. Vehicular ad-hoc network is an...

Vehicular Ad hoc Network (VANET) is a promising technology, which provides the comfort applications and enjoyable drive on the road. To provide safety and accountable network Quality of Service (QoS) parameters, it is essential to design routing protocols in which support VANET environment. Mobile adhoc Network (MANET) offered effective protocols and some of MANET protocols has been used for VA...

Vehicular Ad Hoc Network (VANET) allows vehicles to exchange information about road and traffic conditions through wireless communications. Nevertheless, providing reliable and authenticated information without violating the user's privacy seems contradictory. In this paper, we propose an Anonymous Announcement System especially designed for Electric Vehicle (EV) in VANETs to achieve the aforem...

Vehicu lar ad-hoc networks (VANETs) technology has emerged as an important research area over the last few years. Being ad-hoc in nature, VANET is a type of networks that is created from the concept of establishing a network of cars for a specific need or situation. VANETs have now been established as reliable networks that vehicles use for communication purpose on highways or urban environment...

Vehicular Ad hoc Network (VANET) is very promising technique to increase traffic safety. This will help in saving life of many people from road accidents. VANET uses vehicle to vehicle communication to inform about the location of other vehicles and the traffic density. There are many routing protocols described in VANET. Position-based protocols are best suited in highly dynamic topology envir...

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...

A Vehicular Ad hoc Network (VANET) consists of vehicles which communicate with each other and exchange data via wireless communication links available between the vehicles which are in communication ranges of vehicles to improve the road safety in city. The communication between vehicles is used to provide road safety, comfort and entertainment. The performance of communication depends on how b...
