We present the technologies and the theoretical background of an intelligent interconnected infrastructure for public security and safety. The innovation of the framework lies in the intelligent combination of devices and human information towards human and situational awareness, so as to provide a protection and security environment for citizens. The framework is currently being used to support visitors in public spaces and events, by creating the appropriate infrastructure to address a set of urgent situations, such as health-related problems and missing children in overcrowded environments, supporting smart links between humans and entities on the basis of goals, and adapting device operation to comply with human objectives, profiles, and privacy. State-of-the-art technologies in the domain of IoT data collection and analytics are combined with localization techniques, ontologies, reasoning mechanisms, and data aggregation in order to acquire a better understanding of the ongoing situation and inform the necessary people and devices to act accordingly. Finally, we present the first results of people localization and the platforms’ ontology and representation framework.
Although QoS provision has been researched extensively for B-ISDN (ATM based) networks and it is also under research for IP networks (Internet), until recently there was no real service environment to provide such QoS to end users. Demonstrators and laboratory experiments aimed mainly at proving specific technologies and architectures. Recent advances in the commercialisation of technology and respective standardisation effort have changed the scenery. End to end networks, capable of QoS support, are in a maturity status that will enable commercial deployment within the next few years. Still, there are no applications to take advantage of such services. It would be most desirable to enhance the way users use current applications (such as the established WEB browser), than to try to introduce new application S/W. This paper proposes a method based on the Open Service Gateway initiative (OSGi) specification [1] that enables the Quality of Service (QoS) for bandwidth demanding applications such as multimedia applications, by introducing S/W modules as enhancements into the existing applications. This method targets to the end-user, when using the network topology that is being standarised by the Full Service Access Network (FSAN) [2].
In this paper we present the experience gained from the design and verification of a complex network processor. The PRO 3 processor 1 can operate in either ATM or IP based multiprotocol networking environments, supporting link rates up to 2.4 Gbps. We describe the methodology followed during the verification process, from specifications to silicon prototype test and highlight the problems encountered during the post-layout procedure. To accommodate the application verification a proprietary Debug Tool is integrated in the system. The paper emphasizes the importance of the verification, addressing it as a parallel process to system design, and highlights the need for easy to verify designs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
