To ensure traffic flow and its safety, it is necessary for the vehicle crew to dispose information about current road conditions. One of common approaches broadcasting in VANET (Vehicular Ad hoc NETwork). In VANET, broadcast can be used exchange between several types nodes, especially vehicles, but also Road Side Units (RSUs). However, most important vehicles. This article introduces design imp...

To enhance vehicular ad hoc networks (VANETs) with the ability to detect road conditions, hybrid VANET-sensor networks (HVSNs) additionally deploy a large number of wireless sensors on road sides, so as to provide a safer driving environment. Most of the previous works on network deployment problems considered too simplified problem settings, and few of them focused on deploying HVSNs. To meet ...

In the last decade, user demand has been increasing exponentially based on modern communication systems. One of these new technologies is known as mobile ad-hoc networking (MANET). part MANET called a vehicular network (VANET). It different types such vehicle-to-vehicle (V2V), delay-tolerant networks, and vehicle-to-infrastructure (V2I). To provide sufficient quality service in Vehicular Delay-...

Given the enormous interest shown by customers as well industry in autonomous vehicles, concept of Internet Vehicles (IoV) has evolved from Vehicular Ad hoc NETworks (VANETs). VANETs are likely to play an important role Intelligent Transportation Systems (ITS). based on fixed infrastructures, called Road Side Units (RSUs), have been extensively studied. Efficient, authenticated message dissemin...

The integration of Ambient Backscatter Communication (AmBC) with Non-Orthogonal Multiple Access (NOMA) is expected to support connectivity low-powered Internet-of-Vehicles (IoVs) in the upcoming Sixth-Generation (6G) transportation systems. This paper proposes an energy-efficient resource allocation framework for AmBC-enabled NOMA IoV network under imperfect Successive Interference Cancellation...

Vehicular Ad-hoc Network (VANET) is vulnerable to many security threats including Sybil attack due to its open infrastructure. In this paper we have proposed a scheme to detect Sybil attacks using Digital Signature. The infrastructure needed includes vehicles, Road Side Units (RSUs) and Department of Motor Vehicle (DMV). In Sybil attack the malicious node, called Sybil attacker, illegally claim...

Vehicles are among the fastest growing type of connected devices. Therefore, there is a need for Vehicle-toEverything (V2X) communication i.e. passing of information from a Vehicle-to-Vehicle (V2V) or Vehicle-to-Infrastructure (V2I) and vice versa. In this paper, the main focus is on the communication between vehicles and road side units (RSUs) commonly referred to as V2I communication in a mul...

—In this paper, we propose two certificate mechanisms for preventing the Sybil attack in a vehicular ad hoc network (VANET): the timestamp series approach and the temporary certificate approach. We focus on an early-stage VANET when the number of smart vehicles is only a small fraction of the vehicles on the road and the only infrastructure components available are the roadside units (RSUs). Un...

Vehicular Ad-Hoc Network, better known as VANET is a promising new technology which combines the capabilities of different wireless networks in vehicles enabling Intelligent Transportation System (ITS). Vehicular Ad-Hoc networks provide communication between on-board unit (OBU) already integrated in the vehicles and road-side units (RSUs) consisting of on-board sensors, processing modules, and ...

We study the interactions among Internet providers in vehicular networks which offer access to commuters via road side units (RSUs). Namely, we propose a game-theoretical framework tomodel the competition on prices between vehicular Internet providers to capture the largest amount of users, thus selfishlymaximizing the revenues. The equilibria of the aforementioned game are characterized under ...
