Nowadays, with the continuous rise of Internet-based multimedia services, such as video sharing websites, web radios and IP-based telephony, multimedia communications are gaining more and more popularity. From the service provider's perspective, there is an increasing need in providing high-quality content; at the same time, from the network provider's(More)
Today some of the most popular and successful applications over the Internet are based on Peer-toPeer (P2P) solutions. Online Social Networks (OSN) represent a stunning phenomenon too, involving communities of unprecedented size, whose members organize their relationships on the basis of social or professional friendship. This work deals with a P2P video(More)
In recent years, classical Internet applications have been accompanied by the surging of a great variety of new services and exciting possibilities. Among such broad range, two particular phenomena are highly successful: Online Social Networks (OSNs) and Peer-to-Peer (P2P) services. This paper merges these distinct worlds, via the proposal of a P2P(More)
This work describes the main communication services that have to be provided by any emergency network, together with their bandwidth and network requirements. One of them is voice over IP (VoIP), which is fundamental to coordinate all the necessary rescue operations during a disaster event. However, this service alone is not sufficient for the current needs(More)
This paper describes the work that is currently performed in the European FP7 project “A Holistic Approach Toward the Development of the First Responder of the Future”, that is funded by the European Commission under its Security Program. This work aims at providing an overview of a novel emergency network architecture. It represents a(More)
In recent years P2P technology has gained great popularity not only in file sharing applications but also in the field of video distribution. This work proposes a simple model to assess the performance a P2P system designed for video streaming can achieve, measured in terms of average video delivery rate. The model allows to compute system efficiency in a(More)
Peer-to-peer (P2P) technology for TV broadcasting over the Internet is becoming more and more popular in the very last years. This paper introduces a network-wide efficiency metric for P2P streaming systems and develops a mathematical model to explain: (i) the scalability of such architectures with the number of peers, as evidenced by recent measurements;(More)
