Vehicular Ad hoc Networks (VANET) is a subgroup of (Mobile Ad Hoc Networks) MANET which is using for improves traffic safety system. Since the movements of Vehicles are restricted by roads, traffic regulations we can deploy fixed infrastructure at critical locations. We focus our study on the different kind of attacks and its behaviour or impact in safety system and how many challenges; we have...

VANET that stands for Vehicular Ad Hoc Network is a powerful technology to provide the communication between vehicles and nearby RSUs (roadside units). It is a type of Mobile Ad Hoc Network (MANET) to provide the drivers with following services: such as safety warnings to protect them from traffic accidents, jammed traffic information, entertainment etc. In VANETs network topology changes becau...

Vehicular Ad-hoc Network (VANET) is taking more attention in automotive industry due to the safety concern of human lives on roads. Security is one of the safety aspects in VANET. To be secure, network availability must be obtained at all times since availability of the network is critically needed when a node sends any life critical information to other nodes. However, it can be expected that ...

A vehicular ad hoc network (VANET) is a type mobile ad hoc network which is developed to increase physical safety of vehicles’ derivers. Many parameters affect the performance of VANET. Packet size and packet rate are two important parameters that need to be considered when using VANET. Different values of these parameters provide different network performance. Using large packet size leads to ...

the intelligent transportation system (its) provides wireless and mobile communication between vehicles and infrastructure to improve the safety of transportation and make the journey more enjoyable. this system consists of many fixed and mobile nodes (vehicles, trains, vessels, air planes), wireless and wired telecommunication technologies to exchange information between mobile nodes or betwee...

Vehicular Ad Hoc Network (VANET) is an emerging new technology, a type of ad hoc network, combination of various technologies to achieve intelligent inter-vehicle communications and improve road traffic safety and efficiency.This paper shows the performance comparison between unicast and multicast routing in VANETs. This paper evaluate the performance of vehicular ad hoc network using various Q...

Vehicular Ad-hoc Network (VANET) is a sub-family of Mobile Ad-hoc Network (MANET).The means goal of VANET is to provide communications between nearby nodes or between nodes and fixed infrastructure. Despite that VANET is considered as a subclass of MANET, it has for particularity the high mobility of vehicles producing the frequent changes of network topology that involve changing of road, vary...

Vehicular ad-hoc network (VANET) is self-organizing wheeled networks that enable communication in between high speed moving road vehicles like cars, trucks, busses etc. in VANET network each vehicle behave as a mobile node and can be move in any direction with varying speeds that makes highly dynamic environment. The existing mobile ad-hoc network (MANET) routing protocol are unsuitable for VAN...

Vehicular Ad-Hoc Network or VANET is a technology that uses moving cars as nodes in a network to create a mobile network. VANET moves each performing car into a wireless router or node, mainly the involvement of interest to MANETs is of interest in VANETs, but the information diverges. Rather than moving at random, vehicles tend to move in an institutionalized fashion. In this paper rural and u...

today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...
