The rapid development of mobile communication technologies in recent years allows their application for inter-vehicle communication (IVC). In this paper, we evaluate the suitability of two wireless technologies for IVC, namely Universal Mobile Telecommunication System (UMTS) and IEEE 802.11 Wireless Local Area Network (WLAN). We analyze the communication properties of these technologies and point out the requirements of applications for IVC. We present a series of practical experiments to evaluate the eligibility of each technology for applications of IVC. To obtain comparable results, we performed measurements based on IP-unicast communication, since the lower layers of the two communication technologies differ drastically. Based on the recorded data of radio coverage, latency and throughput, we draw conclusions on currently feasible and infeasible applications for each technology.

This paper deals with automotive power line communication for high data rate. Today's automobiles contain many complex systems, each one incorporates a large number of electronic control units. These buses increase the number of cables and interferences. In order to reduce the total amount of cables and EMC, a potential solution is powerline communications (PLC), using multi-carrier modulation. This technique offers both high data rate and good adequacy with channel properties. In the present work, the PLC techniques has been tested in the automotive environment, and the first results seem to be very promising. An optimized modem has been simulated to reach the expected data rate.

Vertical handoff is one of the most challenging issues in heterogeneous network environments. The existing vertical handoff decision methods have some disadvantages such as unfeasibility, ping-pong effects and inefficient utilization of wireless network resources. An application-oriented cooperative vertical handoff decision method for multi-interface mobile terminals is proposed in this paper. It supports cooperation among heterogeneous network interfaces. Different QoS requirements of various application types are considered in weight value determination. The handoff decision follows "per application" and "the most suitable" principles for efficient network resources utilization. Simulation results show that the proposed method can reduce the unnecessary handoff and realize well tradeoff between the performance optimization of single application and efficient utilization of network resources.

In this paper, we present a Fleet Management Center application implemented using a stream processing infrastructure we call System S. System S enables the deployment of large scale applications with mechanisms for sharing multi-party data sources, software components, and even intermediate results. This approach significantly reduces the cost of software integration, and ownership, the major factor in Intelligent Transportation Systems. In addition, the system includes an adaptive data source management that determines the list of relevant data sources based on the current locations of the entities monitored or managed by the applications.

This paper deals with MIMO channels modeling in tunnels. A full 3D ray-tracing based simulator is used to simulate the MIMO channel in a 1-track tunnel for various antennas configurations at the transmitter and at the receiver. A parametric study is described. The main purpose consists in determining correlation based MIMO channel statistical models and evaluating their performances in an empty tunnel. Channel models obtained with the Kronecker and the Weichselberger models are compared in terms of envelope of the matrix coefficients distribution and mean channel capacity. The best configurations which model correctly the channel while maximizing its capacity will be given.

IVC(inter-vehicle communication) is one of the most important research topics in ITS (intelligent transport systems). In the IVC scheme using DS/CDMA (direct sequence/code division multiple access), allocation of PN codes is a major problem to be solved. In this paper, a good PN code allocation scheme for the DS/CDMA IVC system that allocates each PN code to the position on the road is examined by computer simulation. Five kinds of the PN code allocation maps are compared under several conditions.

Summary form only given. The Satcoms in Support of Transport on European Roads project (SISTER) will promote the integration of satellite and terrestrial communications with GALILEO to enable mass-market take-up by road transport applications. Again SISTER does not aim at satellite to be the sole means of communications for all applications, rather it is seen as part of an overall solution. The project is supported by the European Commission under the 6th frame programme for Research and Development. It is lead by Avanti Communications (UK) with the support of a team of industrial and academic partners covering all aspects of the value chain for ITS services, from R&D through to space infrastructure and communications delivery.

New information and communication technologies revolutionized our current way of life. The rapid growth of these techniques reveals new needs, which contribute to the development of telecommunications in terrestrial transportation field. The trend today is to provide seamless connectivity services both for operations and passengers' applications. These services allow operators to optimize exploitation and maintenance costs but also to enhance friendliness, comfort and security feeling of public transport by offering new services to passengers while travelling. All these applications require high data rate in uplink and downlink directions. In order to save huge terrestrial infrastructure deployment, our work considers an architecture based on the use of a satellite and a terrestrial link function of the availability of each system. In the final application, vertical handovers between the two links versus system availability will be implemented. This paper investigates the performance of the terrestrial link only over time varying channel when the receiver moves with a very high speed. This terrestrial link is based on a very similar physical layer to the IEEE802.16a standard. The performances of such a system are analyzed over a new Rayleigh fading channel simulator through simulations. First experimental results obtained at lower speed with a real transmission chain based on the simulated one are presented.

Automotive telematics is expected to be prevalent due to both market pull and technology push driving forces. By considering ITS networking needs, auto-telematics should provide mobile Internet services for fulfill these needs, and IPv6-based auto-telematics might effectively achieve IP ubiquity and network mobility, which are key technologies for mobile Internet. In this study, an IPv6-based automotive telematics is developed to investigate IPv6 networking systems for ITS. The prototype is made for field trials and performance evaluation purposes.
