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...

VANET (Vehicle Ad-hoc Network) is an emerging technology in today’s intelligent transport system. In VANET, there are many moving nodes which called the vehicle running on road. They communicate with each other to provide information driver regarding road condition, traffic, weather and parking. a kind of network where talk help equipment. There various things also make complete like OBU (onboa...

Intelligent transportation systems (ITS) are a today´s hot topic, especially in the context of development information technologies, which can be employed transportation. Although scope and technical solution these may vary, they frequently based on VANET (Vehicular ad hoc network), i.e. communication network, is primarily generated among moving subjects, form ITS. Given highly dynamic VANET, ...

A Vehicular Ad hoc NETwork (VANET) is a type of mobile Peer-To-Peer wireless network that allows providing communication among nearby vehicles and between vehicles and nearby fixed roadside equipment. The lack of centralized infrastructure, high node mobility and increasing number of vehicles in VANETs result in several problems discussed in this paper, such as interrupting connections, difficu...

Vehicular ad-hoc network (VANET) is high dynamic wheeled networks in which moving vehicles that can move in any direction at varying speed are behave as network nodes and router for data exchange. The frequently changes in topology and mobility pattern in VANET pose many unique networking research challenges which make crucial the designing of an new suit of efficient routing protocol for VANET...

In Vehicular Adhoc network (VANET) safety applications, the source vehicle that detects an accident can generate a warning message and propagate it to the following vehicles to notify other drivers before they reach the potential danger zone on the road. Recent studies have shown that sparse vehicle traffic leads to network fragmentation, which poses a crucial research challenge for safety appl...

In IEEE 802.11p protocol of Vehicular Ad-Hoc network (VANET), the multiple channels are divided into one control channel (CCH) and six service channels (SCHs). CCH is used for broadcasting safety messages related to road conditions, so that CCH access algorithm has great influence on efficiency of VANET. This paper proposes a contention-free bandwidth partition algorithm, which can dynamically ...

Vehicular Ad Hoc Networks (VANET) is a subclass of Mobile ad hoc networks which provides a distinguished approach for Intelligent Transport System (ITS). The survey of routing protocols in VANET is important and necessary for smart ITS. T his paper discusses the advantages / disadvantages and the applications of various routing protocols for vehicular ad hoc networks. It explores the motivation...

Vehicular Ad Hoc Network (VANET) is a wireless network formed between a collection of vehicles connected through wireless connections. VANETs can help increase the passengers‟ comfort, safety, efficiency and convenience by providing them with information about the ongoing road status and other relevant road information. VANETs, similar to other networks, face numerous security threats. One such...

In the performance evaluation of a protocol for a vehicular ad hoc network, the protocol should be tested under a realistic conditions including, representative data traffic models, and realistic movements of the mobile nodes which are the vehicles (i.e., a mobility model). This work is a comparative study between two mobility models that are used in the simulations of vehicular networks, i.e.,...
