Since a widgets can be recognized as a unit providing a specific service, from the perspective of choreography, this paper adapts widgets into a mobile Peer-to-Peer (P2P) environment and propo...

ÐAs a result of the increased popularity of group-oriented applications and protocols, group communication occurs in many different settings: from network multicasting to application layer teleand videoconferencing.

We investigate how a collusive group can sustain non-Nash actions by enforcing internal discipline through costly peer punishment. We give a simple and tractable characterization of schemes that minimize discipline costs while preserving incentive compatibility. We apply the model to a public goods contribution problem. We nd that if the per-capita bene t from the public good is low, then regar...

We propose the peer object-group design pattern as a suitable architectural solution to structure and implement synchronous groupware applications. We discuss a reliable group-communication subsystem and a distributed objects model, implemented in Java, used to realize the approach. 1. Characterizing Groupware "Computer Supported Cooperative Work" CSCW, deals with the use of computer systems by...
