Abstract: Aimed at a class of wireless networked control systems based on the wireless sensor networks, the sources of networkinduced delay were identified for closedloop system. With an aim to decrease the impact of the networkinduced delay on the system, from the viewpoint of the wireless network, a novel routing algorithm that can minimize the total roundtrip time delay for wireless networked control system was presented and the implementation of the algorithm was recited in detail. Furthermore, the effectiveness of the routing algorithm was validated with the experiment.
Key words: wireless sensor network; wireless networked control system; networkinduced delay; routing
