In the IEEE 802.11 standard, a Mobile Station (MS) associates to an Access Point (AP) which has the best Received Signal Strength Indication (RSSI) value during its scanning. However, in 802.11-based wireless mesh networks, the conditions of the access link (e.g., traffic load of associated stations, and the frame error rate between the MS and the Mesh Router (MR)) and the conditions of the mesh backhaul (e.g., end-to-end latency, and asymmetric uplink and downlink transportation costs) have significant impact on the network performance of the MS after its association. In this paper, the authors propose a cross-layer association scheme for wireless mesh networks.
