Connecting components with soft system buses: a new methodology for design, development, and maintenance of reconfigurable, ubiquitous, and persistent reactive systems

From the viewpoints of ubiquitous computing and component-based software engineering, this paper proposes a new methodology for design, development, and maintenance of reconfigurable, ubiquitous, and persistent reactive systems: using soft system buses to connect all components of a reactive system such that no direct interaction is allowed between any two components. Following this methodology, system designers and developers can build persistently reactive systems such that they can be easily maintained, upgraded, and reconfigurated during continuous running by replacing an old or problematic component with a newer or sounder one, removing some useless components, and adding some new components for satisfying new requirements.
