Indoor Link Quality Comparison of IEEE 802.11a Channels in a Multi-Radio Mesh Network Testbed
The most important criterion for achieving the maximum performance in a Wireless Mesh Network (WMN) is to limit the interference within the network. For this purpose, especially in a multi-radio network, the best option is to use non-overlapping channels among different radios within the same interference range. Previous works that have considered non-overlapping channels in IEEE 802.11a as the basis for performance optimization, have considered the link quality across all channels to be uniform. In this paper, the authors present a measurement-based study of link quality across all channels in an IEEE 802.11a-based indoor WMN test bed.
