Poster: Accordion: Toward a Limited Contention Protocol for Wi-Fi 6 Scheduling

Target Wake Time (TWT) is a new scheduling capability in Wi-Fi 6 that can improve network performance by reducing contention and increasing energy efficiency. In this paper, we revisit the classic Adaptive TreeWalk Protocol (ATWP) and show its relevance to the TWT-based scheduling problem in Wi-Fi. Inspired by ATWP, we propose a new algorithm, Accordion, which dynamically switches between contention-based and collision-free channel access strategies using TWT. Preliminary simulations show that Accordion can significantly enhance Wi-Fi network performance in terms of average throughput and latency with varying network loads.
