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...

A Vehicular Ad hoc NETwork (VANET) is a special subset of multi-hop Mobile Ad hoc Networks, in which the vehicles wireless interfaces can communicate with each other, as well as with fixed equipments alongside city roads or highways. Vehicular mobility dynamic characteristics, including high speed, predictable, restricted mobility pattern significantly affect the performance of routing protocol...

A Vehicular Ad-Hoc Network or VANET is a sub form of Mobile Ad-Hoc Network or MANET that provides communication between vehicles and between vehicles and road-side base stations with an aim of providing efficient and safe transportation. A vehicle in VANET is considered to be an intelligent mobile node capable of communicating with its neighbours and other vehicles in the network. VANET introdu...

In the whole world the number of automobiles are increasing day by day therefore lot of problems occurring on roads such as road accidents, less control on traffic etc. To overcome these problems intelligent technologies are introduced for maintaining the traffic. The VANET is best technology which gives the idea of communication between vehicles. A vehicle in VANET is considered to be an intel...

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...

Wireless communication between vehicles enables both safety applications, such as accident avoidance, and nonsafety applications, such as traffic congestion alerts [1] with the intent of improving safety in driving conditions. Because the high costs of implementing limited test-bed environments constrain prototype testing, VANET researchers often turn instead to simulation toolsets from which a...

Nowadays, everything is moving towards the infrastructure less wireless environment to bring the smartness of the society. In this situation, it is necessary to bring the smart technologies in the adhoc network environment. As vehicular traffic is a foremost problem in modern cities and on highway. Huge amount of time and resources are wasted while traveling due to traffic congestion. VANET is ...

VANET has attracted a good deal of attention owing to its wide range of important applications. VANET is a special kind of mobile ad hoc network, in which most of the nodes are spatio-temporally volatile fast-moving vehicles. Hence, it is extremely difficult to provide resilient end-to-end communications in VANET, although it is a cornerstone for the wider deployment of VANET applications. In V...

Vehicular Ad hoc Network (VANET) is a special type of Intelligent Transport System (ITS), The design of routing protocols in VANETs is important and necessary issue for support the smart ITS. The key difference of VANET and MANET is the special mobility pattern and rapidly changeable topology. Existing routing protocols of MANET are not suitable for VANET. This paper proposes SD-AOMDV as VANET ...

The Vehicular ad hoc network (VANET) is an emerging new technology. Developing multi-hop routing protocols for urban VANETs is a challenging task. VANET is one of the influencing areas for the improvement of Intelligent Transportation System (ITS) in order to provide safety and comfort to the road users. Besides safety applications VANET also provide comfort applications to the road users. Auto...
