802.11-based wireless mesh networks (WMNs) as last mile solutions frequently become bottlenecks in the overall Internet\ncommunication structure. The lack of end-to-end capacity on routes also affects vertical traffic coming from or flowing towards\nexternal networks, such as the Internet. The presented approach aims to increase the overall network performance by exploiting\nchannel diversity and to additionally favor vertical traffic. To achieve this, first we propose a general system that modifies an existing\nmesh node architecture, in order to prepare a more efficient resource management and to enhance the restricted transmission\ncapacity in standard WMNs. The parallel use of nonoverlapping channels, based on a multiradio node, marks the starting point.\nThe system treats aspects of channel assignment, traffic analysis, and fast layer 2 forwarding. Then, the impact of a novel Multihop\nRadio Resource Management process is discussed as a relevant component of this new system architecture.The process combines\nper-hop priority queuing and load balancing in a novel way. It was designed, developed, and evaluated in the presented paper,\nresulting in the fact that capacity in WMNs was significantly increased, Quality-of-Service parameters were improved, and more\nefficient use of multiple radios could be reached.The proposed process was validated using a simulation approach.
