| Abstract: | This paper studies consensus problems in weighted scale-free
networks of asymmetrically coupled dynamical units, where the
asymmetry in a given link is determined by the relative degree of
the involved nodes. It shows that the asymmetry of interactions has
a great effect on the consensus. Especially, when the interactions
are dominant from higher- to lower-degree nodes, both the
convergence speed and the robustness to communication delay are
enhanced. |
