Abstract
This paper describes the design, implementation, deployment, and performance evaluation of a Service-Oriented Wireless Context-Aware System (SOWCAS), a distributed pervasive system having computers, a context-aware middleware server and mobile clients that support context-awareness and high adaptation to context changes for distributed heterogeneous indoor and outdoor mobile ubiquitous systems and environments. The client SOWCAS application runs on different mobile platforms and exploits the modern wireless communication facilities provided by the new state of the art mobile devices. The client architecture is designed and implemented with paying attention to supportability features, i.e., understandable, maintainable, scalable, and portable, real-time constraints, and using service-oriented and object-oriented design principles and design patterns. The SOWCAS Server provides basic and composite services for mobile clients and handles indoor and outdoor context information. The implementations were tested at the Fatih University campus and given as typical mobile context-aware scenarios from a campus life of students and academicians in the paper.
