Dedicated short-range communications (DSRCs) is a novel short- to medium-range wireless protocol designed for automotive use. The DSRC signals are circularly polarised and allocated in the 5.8 GHz band. Described is the development of a monolithic and compact patch antenna with left-hand circular polarisation intended for the on-board unit equipment of a DSRC system. The 40×60×2.455 mm fabricated prototype exhibits a circularly-polarised gain of about 5.52 dBc with a cross-polar discrimination of about 20 dB. © The Institution of Engineering and Technology 2013.

The correct management of resources that can become unavailable over time and the efficient (in terms of both cost and time) re-allocation of the services they provided before becoming unavailable, is an open problem that arises in a wide range of application domains. Despite to some differences, many scenarios spanning very different domains, from logistics to industrial automation, from telecommunication to water systems, may be considered as instances of a more general situation, and the actions to take in order to solve the unavailability problem follow similar patterns. In this paper we discuss the implementation of a multiagent system for solving unavailability problems in an artificial - although realistic - scenario which takes inspiration from to the electricity power network domain.

The task of improving the effectiveness of public safety communications has become a main priority for governments. This is partly motivated by the increased risk of natural disasters such as flooding, earthquakes, and fires, and partly due to the risks and consequent impact of terrorist attacks. This article focuses on the experience from the European Commission Seventh Framework Programme project known as EULER, which seeks to demonstrate the benefits of software defined radio technology to support the resolution of natural disasters of significant stature, which require the participation of different public safety and military organizations, potentially of different nations. In such scenarios, the presence of interoperability barriers in the disaster area is a major challenge because different organizations may use different wireless communication systems. In this context, the main aspect investigated in EULER is the definition of a common waveform that respects the software communications architecture constraints, and guarantees maximum portability across SDR platforms. This article discusses a range of issues that have been identified thus far within the EULER project; in particular, the perceived pan-European interoperability needs of public safety, and coordination with military devices and networks. Aspects of interoperability are also extended to the three dimensions of platform, waveform, and information assurance. © 2011 IEEE.

This article reports a numerical investigation on the transmission performance of multilevel systems operating in building links encompassing step-index plastic optical fibers. For such an aim, a simplified model for the multimode fiber propagation is introduced. A sub-carrier multiplexing technique is also simulated to demonstrate the distribution of broadcasting television channels by adopting such fibers. The reported results show that a unique building network based on step-index plastic optical fibers is suitable to carry both Ethernet and broadcast TV signals in all rooms. © 2012 Copyright Taylor and Francis Group, LLC.

The exponential growth of connected devices, big data and cloud computing is driving a concrete transformation impacting the ICT world. This hyper-connected scenario is deeply affecting relationships between individuals, enterprises, citizens and Public Administrations, fostering innovative use cases in practically any environment and market, and introducing new opportunities and new challenges. The successful realization of this hyper-connected scenario depends on different elements of the ecosystem. In particular, it builds on connectivity and functionalities allowed by converged Next Generation Networks (NGN) and their capacity to support and integrate with the Internet of Things, M2M and Cloud Computing. This paper aims at providing some hints of this scenario in order to contribute to analyze impacts on network issues and requirements and open the way to handle this explosion in data communication, while maintaining consumer expectations and turn data into meaningful social and economic benefits. © 2012 IEEE.
