Abstract
802.11 WLANs in the enterprise and large campus environments must provide Quality of Service (QoS) to large user base. A potential solution is a (static) Tier-2 multi-hop wireless mesh to replace the current Ethernet backhaul distribution network, making WLAN deployment easier, cheaper, and more efficient. However, today’s 802.11 technology does not readily scale in such multi-hop environments. We describe a multi-dimensional adaptation (MDA) framework for interference management based on distributed adaptation of key parameters: physical carrier sensing threshold, transmit power and contention window. In the novel framework, each node adapts its own parameters based on its own local measurements, without any overhead due to information exchanges.
