Content-based Middleware for Decoupled Interactions in Pervasive Environments

The growing ubiquity of sophisticated sensor/actuator devices with embedded computing and communications capabilities, and the emergence of pervasive information and computational Grids require a middleware infrastructure that: (a) is scalable and self-managing, (b) is based on content rather than names and/or addresses, (c) supports asynchronous and decoupled interactions rather than forcing synchronizations, and (d) provides some interaction guarantees. In this paper we propose Associative Rendezvous (AR) as a paradigm for content-based decoupled interactions for pervasive applications. In this paper we also present Meteor, a content-based middleware infrastructure to support AR interactions. The design, implementation, and evaluation of Meteor are presented. WINLAB Proprietary i
