Recently, we proposed interference-aware channel segregation based dynamic channel assignment (IACS-DCA) which selects a channel with low co-channel interference (CCI) by using channel priority table. The transmission performance of a wireless station (STA) located far from access points (APs) degrades due to path loss and shadowing loss. Cooperative diversity is well known to improve the transmission performance. However, an introduction of AP cooperative diversity to IACS-DCA is not easy because different channels are assigned to different APs located nearby each other. In this paper, we propose AP grouping for AP cooperative diversity in a wireless network using IACS-DCA. AP grouping is done based on channel priority table of each AP. By computer simulation, we show that the AP cooperative diversity can improve the transmission performance of IACS-DCA. |
