CADBA: A Context-aware Architecture Based on Context Database for Mobile Computing
Been-Chian Chien, Hsin-Chan Tsai, Yuen-Kuei Hsueh · 2009
Context-aware computing is one of the research fields of pervasive computing. Context-aware systems can react to the user's preference according to the circumstances called context including location, time and other environment conditions. Many context-aware computing paradigms were developed in recent year, however, it is difficult for the present systems to extend the application domains and interoperate with other services due to the problem of heterogeneity between systems. In his paper, we proposed a context-aware architecture based on context database in which the concept of independence is imported. The main idea of the framework is to initiate the physical context independence and the logical context independence into context-aware computing. The architecture thus can easily integrate different service domains and diverse devices into a unifying environment.
