Abstract

In this paper we study IEEE 802.11s-based wireless local area network (WLAN) mesh interworking with external LANs. Interworking with multiple mesh portals is necessary not only for network reliability but also for load balancing and increased throughput. In case, however, two or more mesh portals co...
