Wireless Mesh Networks (WMNs) provide a wireless net work infrastructure that most application scenarios assume to be fixed. Different from highly mobile networks, as sumptions can be made on this infrastructure to increase performance. Now, features in the WiFi protocol stack become unnecessary for doing mesh networking, but still have an impact on the bandwidth performance. The con tribution of this work is to show that WiFi produces a con siderable bandwidth overhead within the WMN backbone infrastructure that could be avoided.
