False Alarm Detection in Cyber-physical Systems for Healthcare Applications

Abstract

Cyber-Physical System (CPS) is an integration of physical processes with computation and communication. CPS connects the virtual world with physical world. It has the ability to add more intelligence to social life. A CPS integrates physical devices, such as sensors and cameras, with cyber (or informational) components to form a situation-integrated analytical system that responds intelligently to dynamic changes in the real-world scenarios. Wireless Sensor Networks (WSN) can be a vital part of CPS as strong sensing capabilities can be one of the major driving factors for CPS applications. Still CPS is considered as a nascent technology and there are many challenges yet to be addressed. These challenges are often posed due to the complexity of communication, computation and the uncertainty of physical processes. CPS can have wide ranging applications, such as smart medical technology, assisted living, environmental control and traffic management. Unfortunately, no unified architecture for CPS has yet been developed, primarily due to variations among the applications. In CPS healthcare application, a wide range of medical sensors are used, however these sensors generate a large number of false alarms. These false alarms add confusion and reduce the efficiency of overall healthcare service. Although a few CPS healthcare architectures have been proposed for healthcare application they all lack of efficient false alarm detection. In this paper, a novel false alarm detection architecture is proposed in CPS for healthcare applications.
