N2 - Our recently proposed interference-aware channel segregation based dynamic channel assignment (IACS-DCA) forms a channel reuse pattern with low co-channel interference (CCI) in a distributed manner. In IACS-DCA, each access point (AP) has channel-priority table, in which the channels are listed by the ascending order of average CCI power. Original IACS-DCA is designed to use the best channel among the available channels. If more-than-one channels are necessary at each AP, multiple channels can be chosen according to their priority information stored in channel-priority table. However, the use of lower-priority channels makes the channel reuse pattern unstable. Therefore, in this paper, we propose multi-group IACS-DCA which divides the available channels into multiple groups and applies IACS-DCA to each channel group. We show, by computer simulation, that multi-group IACS-DCA provides more stable channel reuse pattern and improves the signal-to-interference power ratio (SIR).
