Spaces-Based Communication: an Extension to Support Infinite Spatial Models

Space Integration Services (SIS) is a software communication platform that enables the seamless integration of sensors, actuators, and application-logic components through a multi-space model and a spaces-based publish/subscribe mechanism. The underlying model is based on finite spaces only. SIS has been extended in order to add support for spaces with an infinite number of locations, (e.g., spaces described by continuous coordinates, such as geodetic or Cartesian spaces). The existing conceptual model, valid for finite spaces, is reviewed and generalized to infinite spaces. The obtained model is tested using a prototype implementation realized by means of an additional layer on top of the finite-space version. Finally, the performance of the prototype is then compared to the one of the finite-space version in a series of experimental tests.
