Effect of traffic generation patterns on traffic performance of complex networks

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 to locate the hosts in Erdos-Renyi (ER) random network, Barabasi-Albert (BA) scale-free network and the Internet AS-level network. Our simulation results show that the traffic generation pattern has a significant effect on the traffic performance and provide insights into network design.
