| Abstract: | Nowadays, the IEEE 802.11 wireless local-area network (WLAN) is commonly employed as a common Internet communication access medium. In WLAN, multiple access- points (APs) are usually allocated in a wide network field, which may induce interferences and degrade the performance. On the other hand, a finite number of partially overlapping channels (POCs) are obtainable on the commonly used 2.4GHz band. Therefore, to improve the network performance, it is essential to refine AP allocations with POC assignment and AP-host associations in the network to reduce interference. Previously, we introduced the active AP configuration algorithm to optimize the number of active APs and host associations, and the AP joint optimization algorithm to optimize the transmission power, frequency channel, and CB or non-CB POC to each AP. In this study, we present two extensions to the AP joint optimization algorithm to further improve the performance of WLAN. In the first extension, we consider the pre-processing stage, which identifies the promising APs locations to reduce the search space. In the second extension, we propose the post-processing stage, which further refines the associations of AP-host to enhance the network performance. The proposal’s effectiveness is verified through simulations using the WIMNET simulator in three network scenarios. The simulation results exhibited that the proposal enhanced the throughput performance by minimizing the interference level compared to the existing algorithms. [ABSTRACT FROM AUTHOR] |
