Network-Leading Association Scheme in IEEE 802.11 Wireless Mesh Networks

Free registration required

Executive Summary

The association policy in current IEEE 802.11 networks usually considers Received Signal Strength Indication (RSSI) to be the only metric to capture access link quality. However, when a Mesh Client (MC) in IEEE 802.11-based Wireless Mesh Network (WMN) needs to be associated with the most appropriate Mesh Access Point (MAP), the quality of both the access link and the routing path in mesh backhaul should be considered. To take into account this requirement, most existing approaches rely on MAPs to provide more information for MCs such as traffic load, routing metric and airtime cost, etc.
