In Wireless LAN, the reuse of limited number of channels at multiple access points (APs) leads to co-channel interference (CCI), which significantly affects the throughput performance. By using interference-aware channel segregation based dynamic channel assignment (IACS-DCA), AP can autonomously select a channel so that AP does not receive a large interference. However, the channel selection may not be optimal in terms of spectral efficiency since IACS-DCA allows each AP to use only one channel even though multiple channels are available. Recently, we proposed an interference-aware channel segregation based dynamic multi-channel assignment (IACS-DMCA) which allows AP to use all channels satisfying an acceptable CCI level. In IACS-DMCA, high spectral efficiency can be achieved by assigning each AP multiple channels based on ambient CCI environment. In this paper, we introduce a wireless LAN testbed with IACS-DMCA algorithm that we have developed. By indoor experiment, we show that the wireless LAN testbed operates in accordance with the design. |
