Main Article Content
Abstract
This paper introduces a dynamic channel-assignment algorithm to minimize interference among Access Points (APs) in Wireless Local Area Networks (WLANs). The algorithm utilises Particle Swarm Optimisation (PSO) to efficiently optimise channel allocation, ensuring a positive Signal-to-Interference Ratio (SIR) and Signal-to-Noise Ratio (SNR) for all users, thereby guaranteeing reliable communication. The process commences with an initial channel assignment, followed by iterative refinement using PSO to reduce inter-AP interference. PSO is employed to accurately compute SIR and SNR values for each user, thereby providing a precise assessment of signal quality. Experimental results demonstrate substantial improvements in both SIR and network throughput, confirming the algorithm's effectiveness in reducing interference. Furthermore, the proposed approach is adaptable to various WLAN scenarios, making it suitable for diverse user distributions and network loads, thereby ensuring wide-ranging applicability in real-world settings.
