Channel allocation is an important area of research in open spectrum networks which asserts a significant impact on the spectrum utilization and the fairness among users. This paper studies the optimization of channel allocation, considering multiple objectives. For each objective, a binary programming model is described. Then a new optimization objective called fairness constrained maximum throughput...
In a cognitive wireless network with spectrum underlay, secondary links can transmit at the same spectrum as primary links as long as the interference to the primary links is below a pre-negotiated interference threshold. This paper studies the effect of setting different interference thresholds on the transmission rate of the secondary links and how secondary transmissions affect the primary links...
