초록
IEEE 802.15.4e TSCH MAC is widely used for the industrial market, which require ultra-high reliability and ultra-low power. However, the significance of the TSCH is missing, which is a management function to build and maintain the communication schedule. We address several limitations for Ipv6 over IEEE 802.15.4e TSCH in a large-scale network and propose an enhanced scheme which deals with the configuration of Slotframes, Linkset slots, EB(Enhanced Beacon) management and scheduling information. It supports a dynamic schedule management based on observed resource usage, which achieves industrial-grade performance in terms of jitter, latency, scalability, reliability and low-power consumption.
