In this paper, we study mean first-passage time (MFPT) for random walks on a network through edge iteration. The feature of this kind of network is that every existing edge gives birth to finite nodes at each step. According to the network structures, we obtain the analytical expression for MFPT, which shows that the MFPT grows as a power-law function with the number of nodes in the large limit of...
The Protein-Protein Interaction networks are the typical complex biological networks, and the analysis of their topological characteristics is one of the most important and widely discussed research topics today. This paper analyzes the topological characteristics of a PPI network based on the theory of complex networks, focusing on degree distribution, average path length, network diameter, clustering...
In this paper we study the performance of communication networks from a network science perspective. We study the traffic performance of scale-free network under shortest path and minimum degree routing. We introduce the node usage probability, which depends on both the network topology and routing algorithm, to characterize the traffic load distribution and show that resource allocation based on...
In the letter, we investigate the pinning synchronization in complex networks with non-delay and delay couplings. For the scheme of linear feedback control, synchronization criteria are obtained by Lyapunov stability theory. Sufficient conditions are derived for the synchronization to need the minimum number of pinning nodes. At last, a numerical simulation gives effectiveness of the pinning synchronization...
