A comparison between AFSA2 and EPC Q-selection algorithm, where R c0=0.5, x EPC=64, and Δ=0.3 is a constant. a Transmission efficiency E Aloha. b Mean identification delay \(\bar {d}_{\text {tr}}\) (in TC). Notice that in this figure, the value of \(\bar {d}_{\text {tr}}/100\), instead of \(\bar {d}_{\text {tr}}\) itself, is plotted for EPC Variant II
