Channel Access for Bandwidth Management in Link-Adaptive WLANs with Hidden Stations
Ryoichi Shinkuma, Tatsuro S. Takahashi · 2007
The increase in users of wireless local area networks (WLAN) has raised the need for bandwidth management that prevents bandwidth monopolization and that meets users' requirements. In this paper, we propose and design a distributed channel access mechanism for bandwidth management in WLANs. Our mechanism can flexibly assign bandwidth based on a theoretical estimation, even in poor network conditions, where hidden stations exist and the physical transmission rates vary. The usefulness of our mechanism is validated through evaluations using computer simulations.
