In recent years, peer-to-peer systems have gained traction in a number of important areas including; file-sharing, VoIP and scientific research vehicles such as the grid. We argue that this merely scratches the surface of the potential of peer-to-peer systems. This paper proposes a novel peer-to-peer system, GeoIGM, well suited to the highly collaborative style of tagging and development of context-aware...
Exploiting and deploying telecommunication services on Internet Telephony are imperative for a large market share. However, the distributed nature of peer-to-peer (P2P) network makes services implementation very difficult. In order to meet the research goals of achieving P2P telecommunication services through the union of social and computer networks, we present a society-integrated testbed architecture...
A hierarchical DHT overlay architecture based on P2PSIP is proposed to support a skype-like service. The IETF P2PSIP working group is standardizing a protocol to support any DHT in order to deploy services inside a domain. We extend its functionality to allow the interaction between peers of different domains. Furthermore, we perform an analysis of the routing performance and resource consumption...
Peer to peer (P2P) networks offer higher robustness against failure, easier configuration and are generally more economical as compared to their client-server counterparts. This has made it reasonable for resource consuming and typically centralized applications like voice over IP (VoIP) and, in general, real-time communication to adapt and exploit the benefits of P2P. Such a migration needs to address...
Multipath overlay routing technologies are seen as alternative solutions for VoIP because they inherit path diversity from peer-to-peer overlay networks. We discuss and compare the performances of two relay path selection approaches proposed for VoIP overlay systems through extensive simulations. We propose a new method for relay path computation that takes into account both path disjointness and...
