An Ad-hoc network has a Provision of Quality of Service (QoS) to support many applications like digital and multimedia applications. However, one of the challenging tasks in Ad-hoc Network (MANET &VANET) is Quality of Service (QoS) which is determined by numerous parameters such as bandwidth and delay constraints, varying channel conditions, power limitations, node mobility, dynamic topology, p...

In a 1-D linear vehicular ad hoc network (1-DL-VANET), some vehicles may leave the network (e.g., at highway exits), which may make the 1-DL-VANET disconnected. Thus, it is important to analyze the connectivity of the 1-DL-VANET. When removal of any (k− 1) arbitrary nodes from a network does not disconnect the network, the network is said to be k-connected. In this paper, we investigate the k-c...

A vehicle ad hoc network (VANET) is a solution for road safety, congestion management, and infotainment services. Integration of cognitive radio (CR), known as CR-VANET, needed to solve the spectrum scarcity problems VANET. Several research efforts have addressed concerns CR-VANET. However, more reliable, robust, faster sensing still challenge. novel segment-based CR-VANET (Seg-CR-VANET) archit...

The Vehicular Ad-hoc Network (VANET) has been studied in many fields since it has the ability to provide a variety of services, such as detecting oncoming collisions and providing warning signals to alert the driver. The services provided by VANET are often based on collaboration among vehicles that are equipped with relatively simple motion sensors and GPS units. Awareness of its precise locat...

Vehicular Ad-Hoc Networks, are a specified class of Mobile Ad-Hoc Network, in which vehicles are nodes VANET provides interaction between vehicles and road sides units. VANET now-a-days is affecting a large area of research due to its wide range of applications and special characteristics like movements constraints, On board sensors, Unlimited battery power, high node mobility etc . The main is...

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...

Vehicular Ad Hoc Network (VANET) is appeared to be a new technology to integrate the susceptibility of vastly employed wireless networks to vehicles. The idea is to attain the ubiquitous connectivity for vehicles either through efficient vehicle-to-vehicle or vehicle-to-infrastructure communication that enables the Intelligent Transportation Systems (ITS). In order to design a suitable and effi...

Recent advances in hardware, software, and communication technologies are enabling the design and implementation of a whole range of different types of networks that are being deployed in various environments. One such network that has received a lot of interest in the last couple of years is the Vehicular Ad-Hoc Network (VANET). VANET has become an active area of research, standardization, and...

Recently, a vehicular ad-hoc networks(VANETs) for Intelligent Transport System(ITS) have become able safety and convenience services surpassing the simple services such as an electronic toll collection system. To provide the proper services, VANET needs infrastructure over the country infrastructure. Thus, we have to spend a huge sum of human resources. In this reason, several studies have been...

Vehicular Ad Hoc Networks (VANET) is an emerging and promising technology, this technology is a fertile region for attackers, who will try to challenge the network with their malicious attacks. The security of VANET has mostly directed the attention of today research efforts, while comprehensive solutions to protect the network from adversary and attacks still need to be improved, trying to rea...
