The rapid popularity of wireless networks and portable devices spurs mobile users to access various information services. Service provision in ubiquitous computing has become a challenging issue. In this paper, we present a user-centric service provision model (TJCSPM). UCSPM is designed to support user-oriented quality of service (QoS) evaluation and dynamic service delivery, according to various contexts such as device capability, network status and user preference, etc. Unlike most service provision middleware, UCSPM can provide appropriate services to mobile users, which are not only suitable for being delivered to resource-limited environments, but also with a high degree of satisfaction of users. We have developed a prototype of context-aware expo assistant application to demonstrate the effectiveness of UCSPM.
