A Vehicular Ad Hoc network (VANET) is an emerging technology among the scholars and vehicular industries in recent years. The wireless collision Avoidance (CA) system sends early message to drivers before they reach accident zone on the road. This paper proposed an analytical model for warning messages through collision avoidance (CA) system. Use the Dichotomized head way model, the Braking mod...

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...

Vehicular Ad hoc Network (VANET) is an ad hoc network in which vehicles acts as nodes. It is an application of MANET. VANET is becoming an active area of research because it has tremendous potential to improve safety of vehicles and traffic efficiency. We use the VANET instead of Mobile Ad hoc Network (MANET) due to high mobility of the vehicles as MANET does not support high mobility. Wireless...

Mobile Ad hoc Networks (MANET) is a part of wireless networks. No wires and fixed routers are used in this type of network. It is not everlasting network; it is the short term network. Nodes has the capability to self organize themselves and it follows infrastructure less architecture. Network is formed by number of nodes moving in an inconsistent manner. They do not form any topology. Few exam...

With vehicular ad hoc networks gaining an ever-increasing interest to serve a diverse variety of applications in today’s intelligent transportation systems, it was not at all surprising for the guest editorial team to receive a handful of submissions for this special issue addressing different aspects and test-beds of vehicular networks. In sum, 8 papers were accepted to be published in the spe...

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...

The successful deployment of vehicular ad hoc networks (VANETs) has to overcome the serious security threats which impair the operation of different vehicular applications. This paper presents the vulnerabilities of vehicular ad hoc networks and analyzes some of the security problems inherent in VANETs and also presents proposed solutions to overcome some of the vulnerabilities and security pro...

In recent years, Vehicular Ad Hoc Network (VANET) has developed significantly. Coordination between vehicles can enhance driving safety and improve traffic efficiency. Due to the high dynamic characteristic of VANET, security become one challenging problems. Trust message is a key element in VANET. This paper proposes Manhattan Distance Based Management model (MDBTM) VANET environment which sol...

Vehicular Ad-Hoc Network is a special form of mobile ad -hoc networks (MANETs) which is a vehicle to vehicle and vehicle roadside wireless communication network. VANET is a new standard that integrates Wi-Fi, Bluetooth and other mobile connectivity protocols. The essential requirement of VANET is that it should be able to communicate in any environment irrespective of traffic densities and vehi...
