Formal Modeling Of Middleware-based Distributed Systems

AbstractEffective design of middleware-based systems requires modeling notations that allow the use of process-interaction schemes provided by different middleware packages directly in designs. Traditional design notations typically only support a fixed class of interprocess interaction schemes, and designers wishing to use them for modeling middleware-based systems must devote significant effort to encoding the middleware primitives in the notation. In this paper, we demonstrate how a new graphical design notation, Architectural Interaction Diagrams (AIDs), which provides parameterized support for different interaction schemes, may be used to model a real-life middleware-based system like the Event Heap coordination infrastructure of the i-Room ubiquitous computing environment
