A sensor network query processing system for healthcare data acquisition in Dr. M

摘要

In mobile healthcare monitoring services with wearable sensor devices and mobile communications networks, data acquisition is an important issue for the design and implementation of various healthcare application services. In this paper, we present an efficient healthcare data acquisition apparatus by accommodating the notion of query language and processing functions of the sensor network database system. We present our healthcare monitoring service architecture, query language, and data acquisition process. We show how our proposed system implements the intended healthcare data acquisition facility. Our prototype system has been evaluated by using some example queries and a healthcare dataset of an intensive care unit patients to verify the expressiveness of our query language and efficiency of the healthcare data acquisition to support the healthcare applications.
