Channel Assignment Mechanism for Wireless Local Area Networks (WLANs) - A Survey
For an IEEE 802.11 WLAN with a only AP (Access Point), there are many research efforts in the modification of MAC (Medium Access Control) protocols to find an ideal transmission probability for an effective station to reach the maximum protocol capacity, granted that the number of effective stations associated with the AP is given. Wireless Local Area Networks (WLANs) are subjected to interference because of their working in unlicensed spectrum. Coverage ranges of WLANs are 30 to 300m. Channel assignment is one of the most important problems in the WLANs. In this paper, the authors present a survey on the channel assignment techniques in IEEE 802.11.After analyzing different methods a qualitative comparison has been carried out for various methods by considering execution response, complexity and scalability. They then accomplish the Survey with many research descendants open for further scrutiny.
