The emergence of wireless networked sensors constitutes a hot research topic in embedded system design. Although system resource is seriously limited, operating system applied in sensors has to implement complex task scheduling, which should support concurrent operations, real-time constraint, adaptability and reliability. In this paper, we present a reliable OS scheduling scheme for wireless n...

In many control systems, including networked control systems, feedback information is not necessarily continuous or instantaneous, but intermittent, where the loop is closed for finite time intervals. Intermittent feedback is not uncommon in applications, but it has not been adequately studied in control theory. The aim of this work is to explore theoretically the advantages (and disadvantages)...

Networked control systems where the sensors, controller and actuators of a digital control system reside on different computer nodes linked by a network, aim to overcome the disadvantages of conventional digital control systems at the application level, such as difficulty of modification, vulnerability to electrical noise, difficulty in maintenance and upgrades. However random communication del...
