IPv6-Based Vehicular Cloud Networking

Abstract: In a vehicular cloud network, content-centric approaches are usually employed to seek contents. In the content-centric approaches, data attributes are used for routing instead of a specific address such as an IP address; i.e., data attributes are broadcasted in a vehicular cloud network to seek target contents. This flooding inevitably increases the cost of contents acquisition. To reduce the cost of contents acquisition, we propose an IPv6-based vehicular cloud network where IP-based unicast instead of content-centric broadcast is used to achieve contents acquisition. In this work, a new address structure is proposed to build the relationship between an IP address and a kind of contents, and via this new address contents can be acquired from the nearest vehicular cloud member in the unicast way. This scheme is analyzed and evaluated, and the data show that this scheme effectively reduces the cost of contents acquisition.

iTETRIS : the framework for large-scale research on the impact of cooperative wireless vehicular communications systems in traffic efficiency

Abstract: Cooperative vehicular ICT systems have been identified as an attractive technology to improve traffic management and safety, while providing Internet on the move. To achieve these objectives, cooperative vehicular communication systems allow the dynamic exchange of messages between vehicles, and between vehicles and infrastructure. To ensure the efficiency of cooperative vehicular ICT systems, it is crucial that the communication protocols are adequately designed and optimised, and that the applications using such communication capabilities are tested under realistic conditions. In this context, this paper presents the EU-funded iTETRIS platform that is being created to allow for a realistic and accurate evaluation of the design and impact of cooperative vehicular communication systems and traffic management policies under realistic large-scale scenarios.

Vehicular Networks Security: Attacks, Requirements, Challenges and Current Contributions

Abstract: This article provides a panorama on the security in vehicular networks’ environments. The special characteristics of these environments are presented and a general classification for the different types of attacks illustrated by some relevant attacks examples is introduced. Consequently, some key security requirements and security challenges are derived, considering Intelligent Transportation System (ITS) or Safety services as well as non-ITS or non-Safety services. Finally, some existing contributions in this subject are presented, and their deployment feasibility is discussed.

The emerging applications of intelligent vehicular networks for traffic efficiency

Abstract: Traffic efficiency if one of the key applications of the connected vehicle technology, which uses moving cars as nodes in a network to create a Vehicular Ad hoc Network (VANET). The nodes act as mobile traffic sensors. The technology holds promise for enhancing urban and highway mobility. It is cost-effective alternative to the existing fixed location traffic sensing technologies such as inductive-loop detectors and video image processing systems. In this paper we survey the emerging applications of VANETs for traffic efficiency. We considered green light speed advisory systems, adaptive traffic signals, virtual traffic signals, and cooperative traffic information systems. Topics for future research are suggested. We stress the fact, that due to rebound effects the improvements in traffic efficiency will result in additional vehicle travel (generated traffic). Although net congestion reductions will most likely be observed, it is important to account for rebound effects when evaluating initiatives related to traffic efficiency.
