Fig. 4From: Performance analysis of congestion-aware secure broadcast channels(\(\bar{D_1}\), function \(f_{\text {aw}}\)) versus (\(q_1\), \(P_1\)), under congestion-aware randomized policy in SD-TIN. The rest of the parameters are the following: \(\lambda _1 = 0.1\), \(\gamma _1 = -4.2\,\text {dB}\), \(\gamma _2 = -6.4\,\text {dB}\), \(\alpha =2.2\), \(\beta = 41\,\text {dB}\), \(P_J = 23\,\text {dB}\), \(q_2 = 0.4\), \(B=6\) packets, \(P_{\max } = 23\,\text {dB}\), \(d_2 = 14.6\,\text {m}\), and \(d_{12} = 10 \,\text {m}\). In SD-TIN, \(d_1 = 8.2\,\text {m}\)Back to article page
