This paper presents a video demonstration of a platform for data dissemination for vehicular Networks developed by France Telecom R&D. The aim of this platform is to disseminate infotainment information (e.g. advertisement applications, etc.) in a predefined zone. This platform is based on an optimized dissemination protocol called ROD (Road Oriented Dissemination).
The innovation in wireless technology is to support in the areas of Intelligent Transport System (ITS). Wireless technology can be used in Vehicle-to-Vehicle and vehicle-to-infrastructure in transport applications. ZigBee is the key protocol for sensor network applications because of the long battery life, low-cost for installation, eases maintenance and small footprint. ZigBee enables mesh networking...
The Intelligent Transportation Systems (ITS) currently attract a lot of attention. Many simulators and some testbeds have been proposed to validate new ideas and to guide new theoretical developments. Yet, to this date, simulator tools and testbeds evolve in disjoint research work. We developed Airplug-ns, an open source simulation environment, as a step towards bridging this gap. This environment...
Many applications and protocols are planned for the so-called Intelligent Transportation Systems (ITS). Most of them are supposed to work in dynamic networks, such as the vehicular ad hoc networks (VANET). However, designing and studying distributed applications and protocols in such networks is not easy. Analytical studies suffer from the lack of pertinent models. Simulations are often far from reality...
The complexity and connectivity of modern vehicles has constantly increased over the past years. Within the scope of this development the security risk for the in-vehicle network and its components has risen massively. Apart from threats for comfort and confidentiality, these attacks can also affect safety critical systems of the vehicle and therefore endanger the driver and other road users. In this...
We define an ad hoc transportation system as one that has no infrastructure such as roads (and lanes), traffic lights etc. We assume that in such a system the vehicle are autonomic and can guide and direct themselves without a human driver. In this paper we investigate how a safe distance can be maintained between vehicles. A vehicle which has been compromised by an adversary can cause serious chaos...
Vehicular ad hoc networks (VANETs), similar to other distributed systems, often require a scalable time synchronization service enabling data consistency and coordination. In this paper, we propose a new time synchronization protocol for VANETs, which provides excellent scalability, accuracy and robustness for high mobility traffic scenarios. The new protocol, Converging Time Synchronization (CTS),...
The development of safety and comfort systems in vehicles requires appropriate tool that assists engineers in the development, test, and verification processes. An off-the-shelf tool called CANape has appropriate interfaces to the vehicle bus systems, electronic control units and multimedia recording. CANape has assisted automotive manufacturers and suppliers in developing driver assistance, vehicle...
The main objective of vehicular ad hoc networks (VANETs) is reliable delivery of emergency warning messages so that drivers can make well-timed decisions and prevent mishaps. The dynamic vehicular environment in VANETs makes it necessary to examine its effects on the network to ensure that the messages reach the intended vehicles in its range, on time. The objective of this paper is to monitor the...
The use of IEEE 802.11p for supporting intelligent transportation systems (ITS) enables enhancing the drive experience to provide vehicle users with useful information related to road efficiency and public safety. Safety services, such as collision or sudden hard braking warning, are used to improve passenger safety and reduce fatalities. Along with the delay-critical nature of those services, the...
