In this paper, we study the effect of traffic generation patterns on traffic performance of complex networks. We consider a generic type of networks consisting of two kinds of nodes: hosts and routers. In this kind of network, the traffic performance is closely related to the traffic generation pattern which is determined by the hosts' locations. We evaluate the performance of six kinds of methods...
This paper proposed a novel algorithm to analyze the evolution of regional collaborative innovation systems from the complex network perspective. At first, we illustrate the structure of collaborative networks, which contains several elements. And we found out the system could be regarded as a complex network. As to the evolution algorithm we proposed, in order to match the actual situation, each...
How to enhance the network capacity is one of the most important issues. To achieve this, the existing works have focused on improving either the network structure or routing strategies with a common assumption of uniformly distributing the replicas of information among the nodes in the network. The nodes associated with information replicas are considered as source nodes (or server). However, for...
The environment of information dissemination is represented by complex network. The information here can represent viruses in the network, advertisements, hot topics, public opinions , rumors and so on. A new mathematical model describing the propagation process of information in the complex network is proposed using multi-agent simulation and discrete event simulation methods. The model is developed...
We propose and study a message diffusion network model of IM system with local-world preferential connections and acquaintance introduction mechanisms, which exist in IM system. We put forward the algorithms to generate the message diffusion network model and through simulation results we talk about the topological properties of this network. The topological properties such as degree distribution,...
It is difficult to effectively search for online cooperation because of the complex structure and information asymmetry of the interpersonal trust network. A search method designed in this paper is aiming at finding appropriate persons and their trust related information through the trust ties. Considering the features of the interpersonal trust network, this method extended a search algorithm of...
In order to increase the value of the phrase transition on the regular network, which can be used to measure the capacity of network to process traffic flow, in this paper, we propose a simple traffic flow model for scale-free network based on randomly choosing the shortest path and further discuss the two different routing strategies to enhance the traffic capacity of scale-free networks. The simulation...
