Abstract [en]

Controlled wave interferometry within the passive multi-port (six-port) correlator with capability to accurately process phase information is shown to be a useful technique for microwave radar and wireless sensor applications. In this paper, the co-design and implementation of a complete hardware-software Doppler radar modular system for vital signs detection using the multi-port technology is presented. In contrast to multi-port radio applications, the challenge is to demonstrate the possibility to detect weak, Hz-range frequency signals.

Abstract [en]

This paper presents the design and implementation of a web-based wireless indoor climate control system. The user interface of the system is implemented as a web service. People can login to the website and remotely control the indoor climate of different locations. A wireless sensor network is deployed in each location to execute control commands. A gateway is implemented to synchronize the information between the wireless sensor network and the web service. The gateway software also includes scheduling function and different control algorithms to improve the control result. Additionally, the system security and availability are highly considered in this system. The gateway software implements a warning function which sends warning messages when emergency happens. Finally, the whole wireless control system architecture is modularly designed. It is easy to add different control applications or different control algorithms into the system.

Abstract [en]

As defined by the ZigBee standard, a router should be mains-powered in order to maintain the mesh feature of the ZigBee network. This study presents a method which allows the ZigBee router goes into sleep mode periodically and keeps the same mesh feature during the ZigBee communications. In this study, the standard ZigBee communication is separated into two synchronized clusters. The first cluster includes the communication between end devices and the associated router. The sensor message report time of different end devices are scheduled by the router in different collision-free time slots within a predefined time interval. The second cluster includes the mesh communication between routers and the concentrator. All routers are synchronized so that they wake up at the same time to maintain the mesh feature. In order to maximize the router battery lifetime, algorithms are developed so that the concentrator communicates with routers according to the network routing records. Additionally, in order to recover the broken communication, special logics are implemented in routers and end device so that they can rejoin the wireless sensor network with low power consumption. Finally, a battery lifetime model is presented which can be utilized to calculate battery lifetime of the ZigBee router under different network configurations.

Abstract [en]

This paper presents the methods for the ZigBee network reliability enhancement and the battery life time optimization. The paper begins with the introduction of the common communication problems due to the broken links between sensor module and message relay, or between different relays. Extra message hand shake mechanisms are added to solve different problem mentioned at the beginning. Finally, a general purpose reliability enhancement component is developed as a state machine which can be work together with ZigBee protocol to enhance ZigBee network communication reliability. Moreover, the battery life time of the sensor module during link broken is considerably increased after the enhancement.

Abstract [en]

Methods to improve the reliability and optimize the system latency of our own-developed ZigBee remote sensing system are introduced in this paper. The concept of this system utilizes the ZigBee network to transmit sensor information and process them at both local and remote databases. The enhancement has been done in different parts in this system. In the ZigBee network part, the network topology is configured and controlled. The latency for message transmitting is also optimized. In the data processing part, the network status check function and data buffer function are introduced to improve the system reliability. Additionally, the system latency is measured to compare with the Ad-hoc On Demand Distance Vector algorithm used in the ZigBee standard.

Abstract [en]

Existing systems to collect temperature and relative humidity data at cultural heritage buildings require technical knowledge by people who are working with it, which is very seldom that they do have. The systems available today also require manual downloading of the collected data from the sensor to a computer for central storage and for further analysis. In this paper a wireless remote sensor network based on the ZigBee technology together with a simplified data collection system is presented. The system does not require any knowledge by the building administrator after the network is deployed. The wireless sensor device will automatically join available network when the user wants to expand the network. The collected data will be automatically and periodically synchronized to a remote main server via an Internet connection. The data can be used for centralized monitoring and other purpose. The power consumption of the sensor module is also minimized and the battery lifetime is estimated up to 10 years.

Abstract [en]

This article presents the performance study of a ZigBee module with an external low-noiseamplifier, measured in both outdoor and indoor environments. Our previous study has already shownthat the indoor campus environment such as walls and floors would reduce the radio link rangedrastically and the packet error rate increased. In this study, an external low-noise amplifier has beenadded to a ZigBee module to increase the receiver sensitivity. It is shown that with an external lownoiseamplifier the outdoor radio range can reach up to 403 m with a negligible packet error ratecompared to 144 m without the low-noise amplifier for point-to-point connection. Thus, by increasingthe receiver sensitivity the radio range can be increased without increasing of the radio power outputso that the power consumption can still be kept low to obtain long battery lifetime.
