“…Each domain's policies are described in a declarative language built on logical semantics, with Prolog syntax [20]. This policy model is expressive, non-applicationspecific, and captures interdependencies between policies [21].…”

“…Our implementation used the Panoply middleware [10][11] as a platform, with our notion of domains mapped to the spheres of influence concept. Negotiation is used in Panoply to mediate interactions between spheres (groups of devices characterized by location or social affiliations) and to enable context-sensitive access control through content filtering [20] [21]. A detailed description of Panoply or the policy manager design is beyond the scope of this paper.…”

Abstract-Ensuring spontaneous ad hoc interoperation in decentralized ubiquitous computing environments is challenging, because of heterogeneous resources and divergent policies. Centralized cross-domain service access agreements can be made with a priori knowledge of the interacting entities' policies, but privacy concerns make this approach impractical. Environments should not be too rigid nor too open in their interactions, and should support varying contexts and scenarios. We describe the modeling, design, and implementation of a general purpose negotiation protocol for cross-domain service access agreements between entities that do not share trust agreements or application level protocols. This protocol resolves the constraints and needs of the participants, described in the form of declarative logical policies, in a fully distributed manner, avoiding the need for a third party. We describe how we tested the system and show how negotiation performance was evaluated against an optimal case computed by a centralized oracle.

Abstract-We describe the Smart Party, a new ubiquitous computing application for the home environment. This application gathers musical preferences for guests in different rooms of a party in a user's house. Based on their preferences and available media, it chooses a music play list for each room, adjusting to changing membership as guests move through the party. We describe the application, its architecture, and our implementation of it, including key performance characteristics.
