普适计算室内定位系统研究

Pervasive computing is a new model and use it in the indoor positioning system, so as to provide people with convenient, fast and efficient service. The service must rely on to achieve high-precision positioning algorithm and use sophisticated message handling mechanism. Pervasive computing is the integration of people living in the physical world in a variety of distributed devices, embedded in everyday objects and environments of information distributed computing devices. Pervasive computing systems will be the harmonization of these devices, the information space on behalf of the virtual world and the people living in the real world of mutual integration, to provide users with a transparent service. In the accurate positioning of the premise, this paper researchs indoor location service model, gives the model framework of indoor positioning systems and indoor positioning system block diagram of the message response.This paper will deal with indoor positioning system message-depth study of the mechanism.
