Space-based middleware for loosely-coupled distributed systems

摘要

We describe two distinct distributed systems, MeasureMe and GeoPresence. As with all distributed software systems, these require support for communication, coordination, task distribution and persistent shared data. In this paper, we show how the tuple spaces paradigm provides the required communication and coordination, and how its use facilitates our achieving scalability, extensibility, data persistency and ease of software component upgrades.
