An Approach to the Integration of Peer-to-Peer Systems with Active Entironment

We adopt a form of group communication, called "channeled multicast", for active rooms and other scenarios featuring strict real-time requirements, inherently unreliable communication, and a continuously changing set of context-aware autonomous systems. In our approach, rooted in multi-agent and team programming, coordination and cooperation are supported via ``social awareness'' and overhearing; agents form "implicit organizations" by actively participating to playing a role on a channel. We present an approach to the integration of Internet-based peer-to-peer systems into active rooms by means of agents on "proxy devices" accessing the users' "home peers"; a home peer is a remote or delocalized repository of data and services. In addition to other advantages, our approach introduces a new flavor to the concept of neighborhood in P2P systems, reduces or even avoids the need for users to physically carry P2P-equipped mobile devices with them, and easily supports virtual environments created by the composition of smart rooms at different locations
