IIoT IEEE 802.11ah ΰ MAC


This paper proposes delay-sensitive medium access control(MAC) protocol based on IEEE 802.11ah for industrial internet of things(IIoT). Nowadays the nodes in industiral envriornment are increasing dramtically. However traditional wireless communications are hard to support it. Therefore the proposed MAC  is based on IEEE 802.11ah which can support up to 8192 stations(STAs) per access point(AP). Moreover It aims to reduce delay by first assigning a resitricted access window(RAW) slot in consideration of the delay of each STAs. It is judged that the probability of successful transmission of time-critical data can be increased based on ns-3 simulation.
