Ubiquitous Organizational Information Service Framework for Large Scale Intelligent Environments

In this paper, we introduce a concrete, practical Ubiquitous Organizational Information (UOI) service framework, providing novice users intelligent and useful services with respect to the environment. The UOI framework based on the sensor networks is composed of 3-level hierarchical network architecture. To provide a rich array of services, the modular software framework and foundation software are designed and implemented on our hardware prototype. We define three representative UOI services and illustrate each service flow operating on the proposed UOI network. In addition, we describe some details in the implementation of a distributed UOI network on the UOI test-bed.
