A Recursive Load Balancing technique for VoIP-dedicated WLANs
Gilbert Sawma, Issam Aib, Kablan Barbar, Guy Pujolle · 2008
Intelligent and dynamic management is essential for improving WLAN efficiency, especially when multimedia and other QoS demanding applications are employed. In this paper, we propose a Recursive Autonomic Load Balancing Algorithm (RALBA)for WLANs and test its applicability for a VoIP over WLAN (VoWLAN) use case. A load metric is used to identify how many VoIP flows the WLAN cell can support. RALBA uses a Knowledge Plane to obtain high- level information about network state. The algorithm is presented and illustrated along with implementation plans.
