From: Joint Power Control, Base Station Assignment, and Channel Assignment in Cognitive Femtocell Networks
Downlink aggregate throughput. Similar to uplink, the throughput for the joint power control, base station assignment, and channel assignment scheme at the downlink can be seen to be better than the single MBS WiMAX network and the work by Li et al. This is due to the contention for the single MBS WiMAX network. However, for the work by Li et al., power consumption is less than that of the proposed scheme, since reduced power consumption is considered a priority in their formulation.
