Baroreflex sensitivity (BRS) has emerged as a prognostic factor in cardiology. Spontaneous sequence technique is one of the most commonly used methods in measuring BRS. The technique requires continuous beat-to-beat blood pressure (BP) which, however, cannot be obtained conveniently. Considering that pulse transit time (PTT) is inversely related to BP and can be easily and continuously acquired from...
The RFID is considered to provide an efficient solution to merge physical world with virtual space for pervasive computing. The wireless sensor network (WSN) is also a feasible and cost-effective candidate for the context sensing in the pervasive computing. We propose a smart space named SmartExhibtion as an scenario where the RFID is integrated to the sensor network and describe the whole architecture...
Radio frequency identification (RFID) is a kind of widely used contactless automatic recognition technology. Large-scale deployment of RFID readers and tags provides a very good hardware foundation for ubiquitous computing. A typical RFID system is usually composed of four parts: tag, RFID reader, RFID middleware and application system. To make the RFID reader integration uniform and effective, and...
To make the RFID reader integration uniform and effective, a universal RFID reader communication protocol named RFIDPROBUS is presented. This protocol can be applied to the RFID middleware or application, the collection nodes and the central control system. It is lightweight and can be easily deployed and expanded. To meet the demand of EPC Reader Protocol Standard, RFIDPROBUS is specified in three...
In distributed real-time systems, most of the end-to-end delay fluctuations, especially the delay fluctuations in the network, are bounded provided that the global network traffic loads are manually controlled to be light-weighted. This paper introduces a simple clock synchronization method in distributed real-time systems by using the traffic smoothing technique which is implemented at each end node...
The existing standards of wireless personal area networks (WPANs) in terms of security specifications are not fully applicable to body sensor networks (BSNs) because of some inherent security vulnerabilities and stringent resource constraints. This study outlines a new design proposal of security architecture for BSNs with the purpose of high-level security as well as light-weight protocol. The novelty...
It is suggested using wearable medical devices and sensors as the nodes of body sensor networks (BSN) could allow better long-term monitoring of health condition. Nonetheless, the protocol and criteria for validating these nodes in clinical settings is often overlooked. By using the validation of blood pressure (BP) measurement devices as an example, this paper reveals the need for new standards for...
