Towards Context-Aware Ubiquitous Transaction Processing: A Model and Algorithm
Transaction management for mobile and ubiquitous computing aims at providing mobile users with reliable services in a transparent way anytime anywhere. To make such a vision a reality, transaction processing for the mobile and ubiquitous computing needs to adapt to the runtime environments dynamically. However, most existing mobile transaction models do not consider the context-based transaction management. In this paper, the authors propose a context-aware transaction model and context-driven coordination algorithms. They are built on an event-context action mechanism, enabling the transaction processing to adapt well to dynamically changing transaction context.
