Mobile nodes that are connected in a self-organized way without an underlying hierarchical infrastructure form mobile ad hoc network (MANET)[7]. The MANET is called a vehicular ad hoc network (VANET) in the special case where the mobile nodes are embedded in vehicles. VANET communications, employing a combination of Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) [4,6] wireless com...

Vehicular Ad hoc Network (VANET) is a subset of Mobile Ad hoc Network (MANET). VANET is a self-organized information system composed of vehicles (and possibly additional infrastructure) capable of short-range communication through the device called On Board Unit (OBU). There is a wide range of possible application areas of VANETs, including warning systems, collision avoidance/notification, aut...

The intelligent transportation system is necessary for smart connection among vehicles and roadways equipment. Vehicular Ad-hoc Network (VANET) where are linked together through a wireless link an emerging research area gaining attention this each vehicle node in the ad-hoc network consists of groups stationary or moving vehicles. This dynamic VANET provides infrastructure that builds new solut...

In this paper, we present a reputation assisted trust management mechanism for vehicular ad hoc network (VANET) using privacy preserving trusted group formation. In a VANET, vehicles or road side units can be malicious or malfunction making security essential. A distributed trust management provides a lightweight security alternative to existing security techniques especially in VANET. The trus...

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 ...

Efficient content distribution is one of the emerging applications in vehicular networks. To provide scalable content distribution in vehicular networks, Chord peer-to-peer overlay could be applied. Most P2P protocols, including Chord, are designed for wired-line network, and might perform poorly in mobile networks. Mobile Chord (MChord) is proposed to enhance the P2P performance over vehicular...

VANET, short for Vehicle Ad-hoc Network, is an emerging technology with unique characteristics that differentiate it from previous ad-hoc networks. Designing effective routing protocol V2V (vehicle-to-vehicle) communication and V2I (vehicle-to-roadside infrastructure) particularly challenging due to the dynamic nature of topology frequent disconnections. VANET plays a crucial role in developmen...

This thesis presents a protocol for intervehicle communication for use in Vehicular Ad Hoc Networks (VANET). VANET is a natural extension of mobile ad hoc networks (MANET) in which the restrictions related to power and mobility are relaxed. The routing protocols used for MANETs are generally dependent on the state of the network. With changes in the network topology, routing messages are genera...

A vehicular ad hoc network (VANET) consists of vehicles, roadside units, and other infrastructures that communicate with each the goal improving road safety, reducing accidents, alleviating traffic congestion. For safe secure operation critical applications in VANET, it is essential to ensure only authenticated vehicles can participate network. Another important requirement for VANET communicat...
