An Efficient Variable Channel Allocation Technique for Wireless Local Area Network (WLAN) IEEE802.11 Standard

The limitation of existing fixed channel allocation caused the degradation on overall throughput of the Wireless Local Area Network (WLAN). This paper proposes a variable channel allocation technique based on the bandwidth requirement and Quality of Service (QoS) of the network. According to this paper’s proposal, the distributed system (DS) of WLAN distributes the available frequency band to access points (APs) or the access points will get required channel bandwidth, in such a manner that the maximum possible bandwidth efficiency will be achieved. The numerical results of the proposed technique are shown in this paper and compared with the existing fixed channel allocation.
