vehicular ad-hoc networks (VANETs) is a self-organized wheeled networks, a broader and challenging class of mobile ad hoc network (MANET) that enable the wireless communication in moving vehicles. Due to some exclusive properties and high dynamic nature, VANETs fetch many innovative challenges. Efficient routing is one of the most challenging issues of such networks. Safety applications demand ...

In different this paper we present the performance evaluation study of a simple broadcast data dissemination technique in new emerging Vehicular Ad hoc Networks (VANETs). Differently from the traditional Mobile Ad hoc NETworks (MANETs), VANETs require particular routing protocols, due to the high dynamism of the network topology, and to different traffic and mobility patterns. For safety and em...

Vehicular Ad-hoc Networks (VANETs) are MANETs (Mobile Ad-hoc Networks) in which the network nodes are primarily located in vehicles. VANETs are a compelling application of ad-hoc networks, because of the potential to access specific context information (e.g. traffic conditions, service updates, route planning) and deliver multimedia services (VoIP, in-car entertainment, instant messaging, etc.)...

Vehicular Ad-Hoc Networks (VANETs) have a highly dynamic network topology due to the constant and rapid movement of vehicles. Therefore, communication in VANETs is mostly affected with disruptions and delays as a result of network disconnections and partitions. Moreover, increasing the geographical coverage area for data dissemination while keeping the data-delivery delay low is a challenge. Th...

Vehicular Ad-hoc Network (VANETs) is a derived version of Mobile Ad-hoc Network (MANETs). They are on its own conFigure. d infrastructure-less network. They provide communication facility between vehicle to vehicle (VV) and vehicle to infrastructure (V-I). Vehicles follow different mobility patterns due to variations in speed. As vehicles have high mobility and dynamic topology; the tendency of...

Vehicular multi-hop ad hoc networks (VANETs) enable the exchange of information between vehicles without any fixed infrastructure. The application range of such networks may cover safety related applications like the warning of drivers about accidents or congestions as well as Internet access e.g. via gateways along the road. The varying conditions in VANETs introduce high requirements on the r...

Vehicular ad hoc networks (VANETs) are an emerging area of interest for the security community. Due to the scale of the network, the speed of the vehicles, their geographic positions, and the very sporadic connectivity between them, security issues of VANETs are very challenging, especially on how to ensure the authenticity of emergency messages efficiently. In this paper, we propose a secure a...

<span>The research area of “optimization random early detection for congestion control in vehicular ad hoc networks (VANETS)” is emerging as a prominent internet, mobile and communication networks. The paper would draw the attention development VANETS wider context internet communications. It touches upon problem that needs to be controlled or avoided smooth performance network. studies f...

Vehicular Ad-hoc Networks (VANETs) are an emerging technology that has much potential development ahead of it. VANETs seek to connect devices contained within vehicles together create services particularly relevant a vehicular environment. They attempt do so without relying on infrastructure assist in the process network topology management. This particular nature leads them provide both unique...

The high mobility of vehicles as a major characteristic of Vehicular Ad Hoc Networks (VANETs) affects vividly the dynamic nature of the networks and results in additional overhead in terms of extra messages and time delay. The future movements of the vehicles are usually predictable. The predictability of the vehicles future movements is a result of the traffic conditions, the urban layout, and...
