Abstract
In the recent past, the frequency distribution in wireless networks was known to be a major issue that resulted in the unfair utilization of wireless channels. The channel assignment becomes extremely complex due to the restricted number of accessible channels for wireless local area network (WLAN) operation. Because WLAN access points (APs) are widely distributed, they begin to interfere with one another because they use the same frequency. To reduce interference, WLAN channels should be properly controlled and assigned. To improve WLAN channel use, this paper presents an optimized channel assignment mechanism. The proposed algorithm attempts to optimize the performance of wireless networks by choosing a channel for each access point (AP) based on the interference from the adjacent RF environment and then choosing the optimal channel that offers the highest throughput. The proposed algorithm evaluated the network performance for parameters such as delay, data dropped, data retransmission rate, and throughput. The proposed optimization algorithm significantly improves average network throughput by 28.07 and 11.28% in comparison to EXGPCSA (extended generalized predictive channel selection algorithm) and SFOA (simulating fisherman fishing optimization algorithm) under varying nodes and other network scenarios.
