A vehicular ad hoc network (VANET) can be described as a special type of Mobile Ad hoc Network (MANET), which uses vehicles to create a mobile network. VANET is the future of transportation system as all the vehicles in network communicate with each other and thus, avoid a sheer amount of accidents on roads. The communication in VANET is at greater risk because the messages are broadcasted and ...

During the last five years, the Federal Communication Commission allocated a frequency spectrum and established public and private service rules for inter-vehicles and vehicleroadside communications. A moving vehicle can use the frequency and services to connect to other vehicles and form a Vehicular Ad Hoc Network (VANET). VANET is a wireless network composed of vehicles and roadside beacons w...

Cognitive radio network and vehicular ad hoc network (VANET) are recent emerging concepts in wireless networking. Cognitive radio network obtains knowledge of its operational geographical environment to manage sharing of spectrum between primary and secondary users, while VANET shares emergency safety messages among vehicles to ensure safety of users on the road. Cognitive radio network is empl...

Vehicular Ad hoc Networks (VANETs) are classified as an application of Mobile Ad-hoc Networks (MANETs) that has the potential in improving road safety and providing Intelligent Transportation System (ITS). Vehicular communication system facilitates communication devices for exchange of information among vehicles and vehicles and Road Side Units (RSUs).The era of vehicular adhoc networks is now ...

The Vehicular Ad-hoc Networks is one of the most challenging research areas in the field of Mobile Ad Hoc Networks. In the VANET most of the messages sent through broadcasting. In VANET connection between two nodes break due to the high mobility of vehicles. So the broadcasting of messages in vehicular ad-hoc network is still an open research challenge and requires some efforts to reach an opti...

To improve the quality of wireless communication and extend the range of applications in Vehicular Ad Hoc Network (VANET), a clustered multi-layer hybrid network structure is proposed by the combination of Wireless Mesh Network (WMN) and Ad Hoc Network. Making use of location information, congestion monitoring and routing switch, we design a geographic routing in VANET for load balancing purpos...

Vehicular Ad hoc Networks (VANET) are offset of Mobile Ad hoc Networks (MANET) made by vehicles communicating with each other. The special characteristic of VANET is high speed of nodes, so the time period of network is very small. Performing routing operation in such high dynamic network environment is difficult process. This work proposes cluster based Ant Colony Optimization routing in VANET...

A very promising direction in intelligent transportation system is the applications based on vehicular ad-hoc networks (VANET). VANET of a country is one of the most importation indicators of its economic growth. In this paper, we analysed the characteristics of VANET network topology using complex network theory. The author contribute VANET model, analyse the statistical properties of complex ...

Recent advances in development of Wireless Communication in Vehicular Ad-hoc Network (VANET) has provided emerging platform for industrialists and researchers. Vehicular ad-hoc networks are multi-hop networks with no fixed infrastructure. It comprises of moving vehicles communicating with each other. One of the main challenges in VANET is to route the data efficiently from source to destination...

In this paper, we study the capacity of Vehicular Ad Hoc NETwork (VANET). Due to the particular topology of such a network, results on the capacity of two dimensionnal ad hoc networks are not convenient. Indeed, the nodes are ditributed on a line (the road or the highway), thus they form a chain of nodes. This particular topology reduces the spatial reuse with regard to two dimensionnal network...
