Load Balancing for QoS Optimisation in Wireless LANs Utilising Advanced Cell Breathing Techniques

Analysis and Evaluation of Dynamic Load Balancing in IEEE 802. 11b Wireless Local Area Networks

“…The results show that this scheme increases the total wireless throughput and decreases the cell delay. Load balancing mechanisms present an element of congestion relief to those APs with a high density of users [7]. Haidar et al [2] proposed a new load balancing algorithm based on power management of APs to reduce congestion at hot spots in WLANs.…”

“…Unbalanced load can to make overloading and network congestion [4]. Load balancing in WLANs is the evaluation of associations in mobile stations at time t k dynamically, and then try to detecting optimal set of mobile stations (MS) under each AP focus on estimation of the states of mobile stations at time t k+1 [7].…”

“…Hence, these algorithms are used for graph coloring and meeting scheduling [7]. Among of them, DPOP is a complete algorithm based on dynamic programming and a utility propagation method that extends tree propagation algorithms to work on arbitrary topologies by means of a pseudo tree structure.…”

Cooperative load balancing in IEEE 802.11 networks with cell breathing

“…Cell breathing techniques consist in dynamically modifying cell dimensions usually increasing or reducing transmitted power. The concept of cell breathing for load balancing in WLANs is explained in [14]: a highly congested AP reduces its coverage radius so that the furthest stations lose connectivity and try to roam to a neighboring AP (less loaded). An underutilized AP may increase its transmit power in order to expand its coverage.…”

Enhanced Channel Assignment and Load Distribution in IEEE 802.11 WLANs

“…Channel assignment and load balancing in IEEE 802.11 WLANs have attracted attention of both industry and academic community [1,2,3,4,6]. In [1,2] an approach is proposed to minimize AP congestion using an Integer Linear Program (ILP).…”
