A vehicular ad hoc network (VANET) is an emerging technology that has the potential to improve road safety and traveler comfort. In VANETs, mobile vehicles communicate with each other for the purpose of sharing various kinds of information. This information is very useful for preventing road accidents and traffic jams. On Contrary, bogus and inaccurate information may cause undesirable things, ...

Broadcasting communications is critically important in vehicular ad hoc networks. Many safety applications need safety warning messages to be broadcast to all vehicles present in an area. Design of a broadcasting protocol for vehicular ad hoc networks is an interesting problem because of challenges posed by broadcasting traffic, high throughput, high reliability and low delay requirements of th...

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...

Two types of ad hoc networks in mobile communications are mainly existing; one is Mobile Ad Hoc Network (MANET) and other one Vehicular Ad Hoc Network (VANET). Vehicular Ad Hoc Network (VANET) is highly demanded wireless ad hoc network. It is based on IEEE 802.11 wireless standard, which facilitates vehicle to vehicle and vehicle to roadside communications through air interface. Federal Communi...

Sybil attack is a security threat wherein an attacker creates and uses multiple counterfeit identities risking trust and functionality of a peer-to-peer system. Sybil attack in vehicular ad hoc networks is an emergent threat to the services and security of the system. In the highly dynamic environment of vehicular ad hoc networks, due to mobility and density of nodes, it is challenging to detec...

Vehicular Ad Hoc Networks (VANETs) have become an emerging area of wireless ad hoc networks in the last years. They facilitate ubiquitous connectivity between vehicles through Vehicle-to-Vehicle (V2V) or Vehicle-to-Roadside (V2R) and Roadside-to-Vehicle (R2V) communications. VANETs aim to improve the safety of passengers and traffic flow, reduce pollution to the environment and enable in-vehicl...

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 ...

Mobile ad-hoc networks (MANETs) have a decentralized nature that makes them suitable for variety of applications [...]

Vehicular ad hoc networks are a long-term solution contributing significantly towards intelligent transport systems (ITS) in providing access to critical life-safety applications and services. Although vehicular ad hoc networks are attracting greater commercial interest, current research has not adequately captured the real-world constraints in vehicular ad hoc network handover techniques. Ther...

The rapid increase of vehicular traffic and congestion on the highways began hampering the safe and efficient movement of traffic. Consequently, year by year, we see the ascending rate of car accidents and casualties in most of the countries. Therefore, exploiting the new technologies, e.g. wireless sensor networks, is required as a solution of reduction of these saddening and reprehensible sta...
