Sniffer channel assignment (SCA) is a fundamental building block for wireless data capture, which is essential for traffic monitoring and network forensics. Most of the existing SCA approaches for cognitive radio networks (CRNs) adopt optimization-based methods and rely on the prior knowledge of the secondary user (SU) activities. To relax this constraint, learning-based methods have been recently...
In day care for a driver, continuous ECG (electrocardiogram) monitoring is required because symptoms of cardiac arrhythmia and hypoxia can occur unexpectedly. To enhance care service and quality for a driver, this study proposed a real-time ECG monitoring system of transmitting ECG signals to Android mobile phones or tablets through Bluetooth transmission in vehicles. These signals are then uploaded...
The Mote architecture is the most popular platform used in wireless sensor network applications. In this architecture, microcontroller is responsible for all jobs, such as scheduling, sampling, computing, and communication. In the past one year, two practical applications: bridge structural health monitoring system and rare animal monitoring system are developed and deployed in Wuxi and Beijing, China...
In this paper we present a novel remote pulse wave monitoring system with hybrid infrastructure network which is based on ZigBee protocol and LAN (local area network) technique. The advantage of this type of network infrastructure is that it can fully make use of the low power consumption of ZigBee protocol in sensor network and the long-distance transmission of LAN technique. Hence, it is a good...
