The proliferation of wireless local area network (WLAN) deployments will likely cause frequent geographical coverage overlap among multiple networks. A recent growing interest is the coordination among WLAN providers for efficient network management. When multiple WLANs co-locate in a small geographic vicinity, the lack of cooperative multi- domain resource management can cause significant performance degradation due to inter-domain interference. Moreover, since WLANs often operate in unlicensed frequency bands shared by various public and private networks, they must cope with the dynamic RF environment involving a diverse set of interference sources. This paper introduces a new cooperative resource management framework for multi-domain WLANs operating in an interference environment. Under the proposed scheme, resource utilization and co-channel interference can be adaptively balanced across the entire integrated system. Simulation results show that the proposed scheme outperforms other schemes without inter-domain cooperation or without the consideration of environmental interference.
