A safe communication scheme for an intelligent Wireless Networked Control System Coordination Agent

Abstract— Wireless networked control systems have begun to gain acceptance during the last decade, largely due to the increased flexibility and lower costs they promise to provide. The pace of application has been held back, however, by the reluctance of industry to make the accommodations necessary to allow wireless paths to be incorporated in process control loops, thus limiting the potential applications and benefits of wireless systems. The problem is that there are conflicts between maintaining the performance of control loops, which can be degraded by slow data rates and delays in wireless paths, and the usual objectives in managing a wireless sensor network, namely freedom to configure the network and to adjust data rates at will, to maximize efficiency and to conserve energy consumption in the network nodes, which are very often battery powered. We address this conflict by developing a new1 component for use in industrial control systems, called a Wireless Networked Con...
