Fig. 15From: On achieving network throughput demand in cognitive radio-based home area networksSimulation results of the total number of active channels I versus: a normalized \(\varepsilon = \frac {\varepsilon }{D_{t}}\), and b fraction of time used for spectrum sensing (i.e., normalized sensing time \(=\frac {T_{s}}{T_{f}}\)). This is for different number of cooperating devices i.e., N=1,2,⋯,6 with more practical scenario in which all network parameters are randomly chosen, i.e., \(D_{t} \sim \mathcal {U}(3.5, 10)\) Mb/s, \(\text {SNR}_{p_{j}}^{(i)} \sim \mathcal {U}(-11, 3)\) dB and \(P(\mathcal {H}_{0}) \sim \mathcal {U}(0,1)\), for all i and j Back to article page
