Channel Management Algorithm for Modeling Network Throughput in IEEE 802.11 WLAN

With the increasing demand of the high quality service applications the 802.11 WLAN (Wireless Local Area Network) performance becomes the important issue. This paper proposes a Channel Management Algorithm to enhance the network performance by balance the load on access points (APs) to maximize the efficiency of available channels. By managing network channels the overall throughput gets maximized. Proposed algorithm starts with the channel assignment to each AP, based on minimizing the total interference between them. The proposed algorithm uses the dynamic scenarios with assigning non-overlapped channels and managing fixed and roaming users in the network. Result shows the proposed algorithm is capable of managing the users load on APs as significantly manages the channels in WLAN, which in turn improves the network throughput.
