In this paper, we develop and implement key network technologies to build wireless IIoT architecture and communication protocol stacks based upon IEEE 802.15.4-2015 TSCH Access Mode. We design a delay-sensitive scheduling mechanism and a dynamic bandwidth allocation algorithm, which are not specified in the IEEE 802.15.4-2015 TSCH standard. Furthermore, fast network formation and maintenance mechanisms are also developed to enhance system performance. The network topology constructed and configured by embedded RPL routing strategy can be observed from the web UI. The packet transmission delay and packet delivery rate (PDR) performance are exhibited to validate the effectiveness of the implementation to achieve the QoS requirements of low delay, high reliability and low power consumption imposed by IIoT environment.
