Over the next couple of years the use of ad hoc networks especially for telematics applications will increase a lot to provide new types of services to passengers within the vehicle. Since the ad hoc environment is very vulnerable to a multitude of different attacks, new methods of securing these network environments have to be developed. In this paper the vulnerabilities of ad hoc networks are...
A vehicular ad hoc network (VANET) can be described as a special type of Mobile Ad hoc Network (MANET), which uses vehicles to create a mobile network. VANET is the future of transportation system as all the vehicles in network communicate with each other and thus, avoid a sheer amount of accidents on roads. The communication in VANET is at greater risk because the messages are broadcasted and ...
A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Multi-hop routing and beaconing approaches are two important research challenges in high mobility vehicular networks. Routing protocols are divided into two categories of topology-based and position-based routing protocols. In ...
Low density of network nodes in Vehicular Ad Hoc Networks (VANETs) outside the rush hours and in peripheral areas limits usability of traditional ad hoc networking, which requires end-to-end connectivity between communicating parties. In this article, we survey how usability of vehicular networks could be escalated with delay-tolerant networking, in which vehicles store and carry network data w...
A Vehicular Ad hoc Network (VANET) is a type of wireless ad hoc network that facilitates ubiquitous connectivity between vehicles in the absence of fixed infrastructure. Beaconing approaches is an important research challenge in high mobility vehicular networks with enabling safety applications. In this article, we perform a survey and a comparative study of state-of-the-art adaptive beaconing ...
The low penetration of connectivity-enabled OBUs is delaying the deployment of vehicular networks (VNs) and therefore the development of vehicular delay tolerant network (VDTN) applications, among others. In this paper we present GRCBox, an architecture based onRaspberryPi that allows integrating smartphones inVNs.GRCBox is based on a low-cost device that combines several pieces of software to ...
In last few years, Vehicular Ad-Hoc Network (VANET) becomes increasingly popular in many countries. It is an important element of the Intelligent Transportation Systems (ITSs). In a typical VANET, each vehicle is assumed to have an on-board unit (OBU) and there are road-side unit (RSU) installed along the roads. A trusted authority (TA) and application servers could be installed in the backend....
