In this paper, we propose a Channel Management Algorithm at the Access Points (APs) of Wireless Local Area Network (WLAN) in order to maximize the efficiency of the network by managing users on different channels such that the overall throughput is maximized. We start with the channel assignment at the APs, which is based on minimizing the total interference between APs. Initially we assign the users at different APs on the basis of the users load. The solution developed in this paper uses a distributed algorithm by assigning non-overlapping channels and managing fixed and roaming users in network. One software agent manages all APs and is able to communicate with its neighbors in order to maximize channel utilization for global throughput. Proposed algorithm result shows efficient management of users on different APs thus increases the channel utilization in WLAN. It also improves the network performance and gives higher throughput.
The developing interest in mobile services increases the demand for well-planned and cautiously managed wireless local area networks (WLAN) deployment. In WLAN, a station can access services of the network through an access point (AP) after associating with it. Any number of access points can be accessed by the station whose signal strength is available from among the APs. But practically, a WLAN station (STA) always associates with the access point with higher signal strength among the APs. In WLAN, mobile stations continuously change their location, which results in an uneven network load allocation. This uneven load dissemination prompts an extensive performance degradation of WLAN. This paper presents mathematical modeling to characterize the WLAN performance by balancing the network load and enhancing network throughput. Riverbed Modeler simulator was used to investigate the performance parameters as network load and throughput of the network.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
