Abstract
Due to the rapid growth of smartphones, tablets, and IoT devices, wireless LAN traffic continues to increase, causing severe congestion in high-density environments. Although IEEE 802.11be introduces Multi-Link Operation (MLO) to improve performance by utilizing multiple links, conventional fixed channel selection and traffic allocation schemes cannot adapt to dynamically changing wireless environments. To address this problem, this paper proposes an adaptive channel selection and traffic allocation method based on a distributed spectrum management database that shares real-time channel utilization information among access points. The proposed method dynamically selects channels and allocates traffic for each MLO link according to both channel occupancy and link capacity, enabling efficient utilization of frequency resources. Simulation results using the network simulator ns-3 demonstrate that the proposed method improves total network throughput compared to conventional approaches in high-density environments.
Simulation results show that TADS achieves higher network throughput than conventional random RU selection under data, real-time, and mixed traffic scenarios, and the results also show that the performance gain depends on the available RU configuration, with greater benefits when different RU sizes are available.
This letter proposes an adaptive multi-link operation (MLO) traffic-to-link allocation scheme (ATLAS) to reduce the latency of multi-link devices (MLDs) by allocating the traffic to links under enhanced distributed channel access (EDCA) uplink scenarios. A Markov chain is constructed to analyze EDCA, and the transmissi...

Two congestion-aware mechanisms for ALI selection are introduced that consider not only channel occupancy, which is measured through the interval between transmissions allowed by Decentralized Congestion Control (DCC), but also local queue conditions, enabling more accurate and responsive ALI selection.

Low Power Wide Area Networks (LPWANs) such as LoRa commonly adopt unslotted ALOHA for its simplicity, but the resulting throughput ceiling (0.183 frames/frame-time) limits scalability. We propose a heterogeneous multi-channel collision resolution system that partitions $M$ channels into contention channels and dedicate...

This paper studies uplink random access in a heterogeneous dual-link IEEE 802.11be network, where single-link devices (SLDs) and multi-link devices (MLDs) coexist under uplink OFDMA random access (UORA) and immediate-access multi-link operation (IAMLO). Although IAMLO can improve throughput and protect the access oppor...
