Dynamic Frequency Selection Through Collaborative Reporting in WLANs
The tremendous growth of 802.11 WLANs has resulted in congestion of the limited unlicensed spectrum, especially in densely populated urban areas. The performance experienced by end-users in such deployments is significantly degraded due to contention and interference among adjacent cells. In order to address this challenge, various studies have proposed mechanisms for allocating the available number of channels to cells. In infrastructure 802.11 WLANs, channel selection is performed solely by the AP. Most implemented approaches result in static channel assignments, which is not consistent with the dynamic nature of the wireless medium.
