For efficient and reliable data transmission, the traffic load should be as uniformly distributed as possible in the network, and the average distance traveled by the data should be short. This criterion has been shown to be fundamental. The key design problem is therefore to find the optimal solution that achieves this criterion. With a fixed network topology, the traffic load distribution and the...
In this paper, we study the traffic performance in communication networks from a complex network perspective. The node usage probability is an effective metric for characterizing the traffic load distribution and how frequently a node is chosen to relay packets in a network. Based on the concept of node usage probability, we propose an effective routing strategy to maintain balanced traffic loads...
In this paper, we study the packet routing process in communication networks. For efficient and reliable data transmission, the traffic load should be as uniformly distributed as possible in the network and the average distance travelled by the data should be short. The Internet has been demonstrated to have small-world and scale-free properties in its topology. Under the shortest path routing strategy,...
Assortativity is an important structural characteristic of complex networks. In this paper, we propose a simple method to generate a network with the desired assortative coefficient but still keep the degree distribution unchanged. We simulate cases with different assortative coefficients and calculate the packet drop probability when the buffer size is limited. The simulation results indicate that...
