摘要：Ubiquitous healthcare systems will monitor patients as they maintain their normal everyday activities, in order to warn the patients or healthcare workers of problems as well as collecting data for trend analysis and medical research. A healthcare application may bring about severe network traffic as patients, biomedical signals, sampling rates increase. This traffic could produce some end-to-end delay. A compression of sensing data may be a solution, but it can also cause an increment of processing time and unexpected errors in healthcare service. In this paper we proposed a component based development framework for context-aware processing for u-healthcare application that can reduce network traffic, by using the framework, the information gathered from the environment and patient condition will be process using the designed component development and send to the user or hospital in form of different services (1) alert message service, (2) location information services (3) condition of patient services. We also present the sensor interface framework and multi-purpose gateway to process the contextual data and send to medical centers, hospital or patients mobile device as u-healthcare services.
