Advanced clock synchronization is a basic requirement of significant importance for the wireless distributed system (WDS). IEEE 1588 standard defines a high precision clock synchronization protocol in measurement and control systems. In this paper, an excellent time synchronization scheme for WDS based on the IEEE 1588 standard is proposed. The application of IEEE 1588 on wireless distributed system...
This paper presents a wireless distributed system to measure transient electromagnetic field in power substations. Taking advantage of flexible short-range wireless technique, the system allows flexible multi-node simultaneous measurement while is of compact size and low cost.
Because of failure of an access point In IEEE 802.11 WLAN, some or all the mobile stations connected to the network via that access-point may lose connectivity. In this paper, the problem of enhancing the survivability of IEEE 802.11 WLAN focusing on tolerating Access Point (AP) failures is addressed. In particular, focus on the problem of overcoming these APs failure working with reconfiguration...
Wireless distributed network is a distributed system based on wireless communication technology to achieve resource share and cooperation. With the gradual consummation of wireless communication network, wireless distributed network has played a more and more important role in distributed testing and controlling field. SMS is a simple text transfer protocol on GSM network. It has been widely used...
In view of the shortcomings exist in current process of medical transfusion, a wireless distributed system for transfusion supervision was designed with infrared detection technology, computer network technology, embedded system technology and wireless transmission technology. The system is a network which consisted of a host computer, transfusion monitors, and interconnection mechanisms between the...
