Figure 3.

Data of the simulation of the proposed model for cell phone communication for β = 1. In the figure we plot the probability $P_2^w\left(\tau \right)$ that in the model a pair of agents with strength w are interacting for a period τ. The collapses data of $P_2^w\left(\tau \right)$ is described by power-law distribution in agreement with the theoretical predictions. In the inset we report the power-law exponent versus the theoretically predicted power-law exponent showing good agreement.
