We address the problem of wireless stations selfconfiguration in a WLAN environment with overlapping access point coverages. We propose and investigate a transport-layer solution called AISLE (Autonomic Interface SeLEction) that builds on top of the SCTP protocol and exploits its multihoming features. Through simulation, we evaluate AISLE?s capability to maximize the throughput of multi-interface stations and to achieve an optimal partition of the stations across overlapping WLANs. Although we focus on a WLAN scenario, AISLE is independent of the technology used at the physical and MAC layers.
