Abstract:
One goal of ubiquitous computing is to enable users to access and perform transactions from any location, at any time and from any device. In a context-aware environment, transaction management is a critical task that requires a dynamic adaptation to the changing context in order to provide service reliability and data consistency. In this paper, we propose a new approach for managing context-aware transactional services. Then we discuss the various researches that have addressed this issue. Finally, we propose a new model for the adaptability of context-aware transactional services called CATSM (Context-Aware Transactional Service Model) and the adaptation mechanisms to implement this model.
