A WSN System Architecture to Capture Context Information for beyond 3G Communication Systems

To enable new context-aware applications and services in future communication systems, wireless sensor networks (WSNs) are required to capture the context surrounding the service user and service related objects. This paper introduces a novel configurable architecture for a WSN system that is able to deliver context information from the sensors to the user in different application environments, and allows its efficient integration into third generation (3G) mobile communication systems in particular into the IP multimedia subsystem (IMS). The proposed architecture offers significant advantages compared to the ZigBee architecture.
