Abstract:
In this paper, we present the design, analytical and simulation results for a wireless Medium Access Control (MAC) protocol, referred to as the “Transmission Gating Time Hyperchannel” (TGT-HC) to support bounded low latency delivery of cyclic control traffic such as generated by close-loop distributed control systems. TGT-HC is based on the contention-free Carrier-Sense Multiple Access (CSMA) Hyperchannel protocol. To enhance its performance, we use a combination of per-flow Time-Aware Shaper (TAS) and First-In-First-Out (FIFO) scheduling to determine its sensing slot assignments. Based on the results, we find that this enhanced protocol comes close to the ideal delay performance of a First-Come-First-Serve (FCFS) single server in handling cyclic traffic.
