Comparison between numerical and theoretical critical points. Log–log plot of the critical thresholds, β_c, as a function of the rate at which packets are injected into the system, λ. Two regions are differentiated: an active and an absorbing phase as indicated. The solid line corresponds to Eq. 6 with $\frac{\langle b_{\text{alg}}\rangle }{\langle b_{\text{alg}}^2\rangle }\frac{1}{N}=0.154$. The agreement is remarkable even though Eq. 6 is derived by using a mean-field approach. The underlying network, infection spreading mechanism and routing protocol are the same as in Fig. 1. Each curve is an average of 10² simulations. Remaining parameters are the same as in Fig. 1.
