Research of architecture for digital campus LBS in Pervasive Computing Environment

A data organization and access mechanism model of the spatial information grid is developed for effectively solving the spatial information share in pervasive computing environment. An architecture of campus location-based services based on grid geographical information system (CLGG) is proposed for services sharing, which composed of location tier, data tier, service tier and application tier. In the end, a prototype system is designed realizing district navigation and real time location and hot district information release, etc. These functions of the prototype validate the feasibility and validity of the mechanism model and the architecture.
