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.,...

Vehicular ad hoc network (VANET) is one of the most modern and promising technologies for revolutionizing the transportation system where vehicles can communicate via a wireless medium. The IEEE 802.11p includes communication between vehicles (V2V) and between vehicle and roadside infrastructure (V2I). VANET provide the communication framework for dissemination of safety critical message such a...

In this paper, the study focuses on the various mobility and handover management schemes for different networks (like heterogeneous/homogeneous networks) in Vehicular Ad hoc Network (VANET). Internet Engineering Task force (IETF) purposed MIPv4/v6 (Mobile Internet Protocol-version4/6) and its enhancements like HMIPv6 (Hierarichal), FMIPv6 (Fast), FHMIPv6, PMIPv6 (Proxy) are various mobility man...

Vehicular Ad Hoc Networks (VANETs) have been envisioned with three types of applications in mind: safety, traffic management, and commercial applications. By using wireless interfaces to form an ad hoc network, vehicles will be able to inform other vehicles about traffic accidents, hazardous road conditions and traffic congestion. Commercial applications (e.g., data exchange, audio/video commun...

Vehicular ad hoc networks (VANETs) are a subclass of mobile ad hoc networks (MANETs). It is a new challenging network environment that pursues the concept of ubiquitous computing for future. VANETs bring lots of possibilities for new range of applications which will not only make the travel safer but fun as well. Reaching to a destination or getting help would be much easier. The concept of VAN...

VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. In VANET, nodes which are vehicles can move safety with high speed and must communicate quickly and reliably. When an accident occurs in a road or highway, alarm messages must be circulated to inform all other vehicles. Vehicu...

Vehicular Ad-Hoc Network (VANET) is one of the essential research field because large increase in usage vehicles on road. Many VANET applications are employed to improve road safety conditions, vehicle traffic, an emergency warning drivers, collision avoidance and other non-safety for comfort. The main aim these modernize various processes associated with vehicles, passengers pedestrians by imp...

Vehicular Ad hoc Network (VANET) is a network of self organized vehicles and road-side infrastructure communicating with each other over wireless, with a view to improve traffic safety and efficiency. Data interchanged over VANETs often play a vital role in traffic safety. Such information must be accurate and truthful, as lives could depend on this application. Thus, Authentication is one of t...

A vehicular ad hoc network (VANET) is a vehicular-wireless network enabling vehicle-to-vehicle (V2V) communications and vehicle to infrastructure (V2I) communications. VANET has been under the international spotlight because various applications can be developed by leveraging those wireless communications to avoid vehicular collisions or to save energies. Most of VANET applications have been de...

Vehicular ad hoc networks (VANETs) are getting a lot of consideration these days due to the various applications and possible benefits they offer for their future users. Safety information exchange allows important applications, such as the alerting drivers during crossroads traversing and track merging, and thus, plays an important role in VANET applications. In a VANET, vehicles will depend o...
