Wireless Local Area Networks (WLANs) are limited in size, geographically distance covered, and bandwidth. To extend a WLAN, interconnecting devices called AP/bridges are used to connect multiple WLANs together to form extended WLANs or bridged networks. In the IEEE 802.1d standard for wireless bridges (WSTP), a spanning tree is built among bridges for loop-free frame forwarding. Although this approach is simple, it doesn't take the full advantage of a meshed network by routing packets via the path that has the most available bandwidth & shortest delay. It doesn't alleviate congestion at the root node. This leads to the slower communication in the wireless N/W.
