Abstract
This paper presents an experimental platform for heterogeneous wireless sensor networks (WSNs) and a middle-ware architecture to support context-aware services (CASs) and location-based services (LBSs). The purpose of this platform is to provide both academia and industry a large-scale experimental environment to test and to verify their newly developed WSN systems. In the middleware architecture, a SENSORINFO gateway is implemented to hide the discrepancy of different WSNs from application developers. Hence, application developers can deploy their CASs and/or LBSs easily without considering the differences of the underlying sensor hardware. To demonstrate the features of this platform, we implement two pilot applications: the People Tracking System and the Green Building Monitoring System.
