Real-Time Data Stream Processing for Ubiquitous Home Network Systems

OSGi provides interoperability between hardware and software, and security for safe access in local network environments. Due to the complexity of service development in a home network environment, the usage of newly emerging sensors which generate real-time sensor data stream is steadily growing in the network, and OSGi application services are also increasing using those sensors. The researches to effectively process real-time sensor data stream generated by those sensors are going on, nowadays. In this paper, we propose OSGi application framework to effectively provide home network services by using real-time data stream in OSGi applications. The method of interoperability with ALE-compliant middleware is also proposed to process sensor data stream in a standardized method.
