Multi-delay network based IEEE 802.15.4 for low delay deterministic networked control systems

Wireless networked control systems have gained significant popularity due to commissioning and maintenance ease. IEEE 802.15.4 standard is one of wireless communication protocol for low delay deterministic network. Factory automation, not only needs low delay but also requires the network that should has the capacity of various delay devices. In this paper, we propose a scheme, satisfying the muli-delay network in the networked control system. Experiments are using TI SmartRF04EB evaluation boards with CC2530 SoC and TIMAC software stack CC2530 boards, as well as dc servo motors for a speed tracking control problem.
