In VANET high speed is the real characteristics which leads to frequent breakdown, interference etc. Therefore Performance of adhoc routing protocols is helpful to improve the Quality of Service (QOS). In this paper we studied various adhoc routing protocols, Reactive, Proactive & Hybrid, taking in to consideration parameters like speed, altitude, mobility etc in real VANET scenario. The AODV a...

To improve the quality of wireless communication and extend the range of applications in Vehicular Ad Hoc Network (VANET), a clustered multi-layer hybrid network structure is proposed by the combination of Wireless Mesh Network (WMN) and Ad Hoc Network. Making use of location information, congestion monitoring and routing switch, we design a geographic routing in VANET for load balancing purpos...

Vehicular Ad hoc Network (VANET) is one type of Mobile Ad hoc Network (MANET). In VANETs, vehicles are connecting to computer networks. VANETs have dynamic nodes in the form of moving vehicles and static nodes in the form of Road Side Units (RSU). Movements of vehicles are limited to road layouts and fast compared to other ad hoc networks. Hence, frequent disconnections are happening in the com...

In VANET high speed is the real characteristics which leads frequent breakdown, interference etc. In this paper we studied various Ad hoc routing protocols, Reactive, Proactive & Hybrid, taking in to consideration various VANET parameters like speed, altitude etc in real traffic scenario and evaluated them for various battery models for energy conservation.. The AODV and DYMO (Reactive), OLSR (...

Vehicular Ad hoc Network (VANET) is a new method of interaction which involves interaction among vehicles running at high velocities on the roads. Vehicular Ad-hoc Network (VANET) is a most vital class of mobile ad-hoc network (MANET) that makes capable roadside vehicles to intelligently communicate with outside infrastructure and with each other anywhere anytime in the worldwide network. A new...

Vehicular ad hoc networks (VANETs) have been a research focus in recent years. VANET’s applications are mostly applied to the road safety and reduce the traffic accident earlier. Moreover, use VANET system can also help the emergency vehicles go to accident location as soon as possible. Therefore how to protect the transmission message is important. We propose a secure emergency vehicle transmi...

VANET (Vehicular Ad-hoc Network) is an emerging new technology with some unique characteristics that makes it different from other ad hoc network. Due to rapid topology changing and frequent disconnection it is also difficult to design an efficient routing protocol for routing data among vehicles, called V2V or vehicle to vehicle communication and vehicle to road side infrastructure, called V2I...

The prime goal of Vehicular Ad hoc Network (VANET) is to provide life safety on the road. To achieve this, vehicles make use of two types of safety messages one is Periodic safety messages (beacons) to exchange status information e.g. position, speed etc. and second one is Event-driven messages to broadcast in case of an emergency situations e.g. accidents, hardbraking etc. The main objective o...

-In the current era, the size as well as the dimensions of traffic is increasing to a huge extend now days. The traffic system throughout the world is making use of technology for tracking, monitoring, congestion control and many other applications. The issue of congestion is very common in big cities where thousands of automobile systems are running on the roads. Vehicular ad hoc networks (VAN...

Safety on roadways is expected to be achieved by using vehicular ad-hoc networks (VANETs). A VANET includes dynamically moving vehicles that communicate for a certain purpose. The routing procedure in the VANET protocol is required to deliver requested data packets to the vehicles in a short period of time. Conventionally, routing algorithms like the ad-hoc on-demand vector (AODV) routing, the ...
