Design and Analysis of Channel Assignment Algorithm for IEEE 802.11 WLAN Network Performance Enhancements

摘要

Wireless local area network (WLAN’s) using single channel have limited bandwidth. Channel interference between Access Points (APs) of WLAN also decreases the network throughput. The solution of this problem is to transmit data simultaneously on multiple channels is considered as an alternative. In this paper, we propose a channel assignment algorithm for wireless local area network (WLAN) to analyse and enhance the network performance. The proposed algorithm finds the best suitable channel assignment option in order to attain desired performance. We use the RIVERBED MODELER simulator to simulate the WLAN environment with different channel assignment schemes. Simulation results with fixed and mobile (STA) stations demonstrate that our proposed channel assignment algorithm improve the network throughput 2 times higher as compare to other channel assignment schemes.
