The proposed algorithm gradually balances the AP loads for the available multiple bit rate choices in a distributed manner and shows the improvement of the fairness via computer simulation.Abstract:
With the development of IEEE 802.11 MAC (medium access control) protocols, efficient utilization of wireless local area networks (WLANs) has become a very important issue. In typical IEEE 802.11 networks, the association between mobile users (MUs) and access point (AP) is based on the signal strength information. As a result, it often results in the extremely unfair bandwidth allocation among MUs. In this paper, we propose a distributed association algorithm to achieve load balancing among the APs. The proposed algorithm gradually balances the AP loads for the available multiple bit rate choices in a distributed manner. We analyze the stability and overhead of the proposed algorithm, and show the improvement of the fairness via computer simulation. Additionally, we have implemented a prototype on a testbed to prove its feasibility.read more

Two-tier dynamic load balancing in SDN-enabled Wi-Fi networks
TL;DR: This work proposes a Software Defined Networking (SDN) solution to address Wi-Fi congestion due to an unevenly distributed load among access points (APs), organizing the SDN controller and the APs into a two-tier architecture so that the controller can evaluate the degree of load balancing among the AP's and decide up to which load level the AP’s can accept association requests without consulting the controller.
