[email protected] Abstract—The rapid development of the wireless an uniformly access to cope with the heterogeneous communication technologies, including wireless sensors, effects, including various context presentation, context intelligent mobile devices, and communication protocols, information, mobile device constraints, and context has led to diverse mobile devices of accessing various middleware [4]. To allow interoperability among the context-aware systems. Existing context-aware systems only various context-aware systems and mobile devices, a focus on characterize the situation of an entity to exhibit the advantage of contextual information association. The common standard is needed to uniformly access context contextual information can represent semantic implications information provided via a fundamental infrastructure. to provide decidable reasoning services, but it has no The Web 2.0 technologies provide a catalytic solution to mechanism to facilitating the interoperability and this problem. reusability among heterogeneous context-aware systems and Within the last two to three years, the Internet has various mobile devices. This study addresses these issues greatly changed our way of sharing resources and developing a Multi-layer Context Framework (MCF) that information. As well known, Web 2.0 is recognized as integrates Web 2.0 technologies into context-aware system the next generation of web applications proposed by T. for supporting ubiquitous mobile environment.
