“…Such technology is currently under investigation and its performances represent an hot topic in the research community [13], [14]. We have also seen the rising of ad-hoc hardware prototypes from industry to support such research trend as recently reviewed in [17] and evaluate in [18]. Also, to improve the performance of ITS applications, these ad-hoc platforms can use network traffic prioritization schema based on lightweight network traffic classification platforms [19].…”

In this position paper we present S 2 -MOVE (Smart and Social Move), a social innovation project funded by MIUR (Italian Ministry of Education, Research and University). S 2 -MOVE is based on a new conception of urban community, that allows citizens to share data and decisions in a smart and innovative way. In order to implement this new vision of urban mobility, called smart mobility, a deep integration among citizens, private and public transportation systems and ICT is required.In this new social and challenging scenario, citizens are not just customers of a service, but they produce and share information to obtain a common goal: a smart and efficient mobility, for everyone. S 2 -MOVE proposes an architecture able to collect, update, and process real-time and heterogeneous information from various electronic devices (tablets, smartphones, electronic control devices in vehicles) and from the actors of the urban scenario (public/private transportation vehicles, pedestrians, infrastructures). Mining such information allows to produce new knowledge which is then made available again to the citizens through specific services. The urban mobility issues to which S 2 -MOVE can offer a contribution, are linked to two crucial aspects: continuous and shared monitoring for real-time management of urban traffic and an interactive mobile information service for drivers. In this position paper, after introducing the rationale of the project, we describe the main technological aspects involved in the design and in the implementation of the S 2 -MOVE architecture. Then, we present a proof of the control approach used to create and manage fleets of vehicles and we provide some preliminary results obtained using simulation.

“…There also exist other interesting testbeds that use IEEE 802.11p, in which this article is focused on. For instance, in [7], it was established a relationship between theoretical measures and the ones obtained with a testbed. According to the authors, their experiments lead to the first public data available from real measurements using NEC Linkbird-MX IEEE 802.11p cards, which showed that the results obtained were closely related to the theoretical figures.…”

The capacity of vehicular networks to offer non-safety services, like infotainment applications or the exchange of multimedia information between vehicles, have attracted a great deal of attention to the field of Intelligent Transport Systems (ITS). In particular, in this article we focus our attention on IEEE 802.11p which defines enhancements to IEEE 802.11 required to support ITS applications. We present an FPGA-based testbed developed to evaluate H.264/AVC (Advanced Video Coding) video transmission over vehicular networks. The testbed covers some of the most common situations in vehicle-to-vehicle and roadside-to-vehicle communications and it is highly flexible, allowing the performance evaluation of different vehicular standard configurations. We also show several experimental results to illustrate the quality obtained when H.264/AVC encoded video is transmitted over IEEE 802.11p networks. The quality is measured considering two important parameters: the percentage of recovered group of pictures and the frame quality. In order to improve performance, we propose to substitute the convolutional channel encoder used in IEEE 802.11p for a low-density parity-check code encoder. In addition, we suggest a simple strategy to decide the optimum number of iterations needed to decode each packet received.
