A wireless ad hoc network is a decentralized type of wireless network. It is a type of temporary computer-tocomputer connection. It is a spontaneous network which includes mobile ad-hoc networks (MANET), vehicular adhoc networks (VANET) and Flying ad-hoc networks (FANET). A MANET is a network that has many free or autonomous nodes often composed of mobile devices that can operate without strict...

Vehicular Ad Hoc Network (VANET) has been drawing interest among the researchers for the past couple of years. Though ad hoc network or mobile ad hoc network is very common in military environment, the real world practice of ad hoc network is still very low. On the other hand, cloud computing is supposed to be the next big thing because of its scalability, PaaS, IaaS, SaaS and other important c...

Vehicular ad hoc networks (VANET) are a class of ad hoc networks build to ensure the safety of traffic. Trust and security remain a major concern in VANET since a simple mistake can have catastrophic consequence. A crucial point in VANET is how to trust the information transmitted when the neighbouring vehicles are rapidly changing and moving in and out of range. The main aim of this paper is t...

VANET is a widely discussed area of wireless communication at present. VANET is a subset of MANET where nodes represent vehicles moving at high pace and vehicle traffic determined regularity. 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 without c...

The new type of Mobile Ad hoc Network which is called Vehicular Ad hoc Networks (VANET) created a fertile environment for research. In this research, a protocol Particle Swarm Optimization Contention Based Broadcast (PCBB) is proposed, for fast and effective dissemination of emergency messages within a geographical area to distribute the emergency message and achieve the safety system, this res...

VANET is an emerging new technology developed by integrating ad hoc network, wireless LAN (WLAN) and cellular technology to enable intelligent inter-vehicle communications and to improve road traffic safety and efficiency. VANET are distinguished from other kinds of ad hoc networks by their hybrid network architectures, node movement characteristics, and new application scenarios. Therefore, VA...

A Vehicular Ad Hoc network is a subclass of Mobile Ad hoc Networks, to provide communication among vehicles and nearby road side units (RSUs). The main goal of VANET is providing safety and comfort for passengers. In this paper, two metrics to measure the connectivity and power requirement of RSUs in VANET have been proposed for power utilization of RSUs in VANET. Based on the metrics two metho...

Wireless networks between vehicles formed by VANET (Vehicular Ad hoc Networks). VANET incorporates the wireless communication and data sharing capabilities to turn into vehicles as a network topology. VANET is showing great potential in research area. Inter-vehicle communication system in VANET improves traffic safety. VANET consists of high dynamic topology, Intermittent connectivity Patterned...

A Vehicular Ad-Hoc Network is a kind of ad-hoc network, and is a self-configuring network of vehicular routers connected by wireless links. Vanet presents new and promising field of research, development and standardization. Vehicular Ad-Hoc Network is a wireless network without infrastructure. Reliable broadcasting in vehicular ad-hoc networks is one of the keys to success for services and app...

Vehicular Ad hoc Network (VANET) is a special case of Mobile Ad hoc Network (MANET) used to establish communications and exchange information among nearby vehicles and between vehicles and nearby fixed infrastructure. VANET is seen as a promising technology used to provide safety, efficiency, assistance and comfort to the road users. Routing is an important issue in Vehicular Ad Hoc Network to ...
