Query: A self-organized particle moving model on scale free network with
  $1/f^{2}$ behavior   In this paper we propose a self-organized particle moving model on scale free
network with the algorithm of the shortest path and preferential walk. The
over-capacity property of the vertices in this particle moving system on
complex network is studied from the holistic point of view. Simulation results
show that the number of over-capacity vertices forms punctuated equilibrium
processes as time elapsing, that the average number of over-capacity vertices
under each local punctuated equilibrium process has power law relationship with
the local punctuated equilibrium value. What's more, the number of
over-capacity vertices has the bell-shaped temporal correlation and $1/f^{2}$
behavior. Finally, the average lifetime $L(t)$ of particles accumulated before
time $t$ is analyzed to find the different roles of the shortest path algorithm
and the preferential walk algorithm in our model.
