An Efficient Strategy To Improve Traffic Capacity Of The Scale-Free Network By Link-Directed Method
JOURNAL OF THE PHYSICAL SOCIETY OF JAPAN(2020)
Abstract
How to improve traffic handing capacity of network is one of the important problems in network science due to its important implication for various modern communication networks. In this paper, we present an efficient method to enhance the traffic capacity of network via the process of enforcing a fraction of the undirected links to be unidirectional based on the degree and betweenness of nodes, which we name the high-betweenness-degree-first method. Extensive simulations have been performed to estimate the effectiveness of the proposed method under the shortest path routing strategy. It is found that our proposed method can result in higher transmission efficiency compared to the high-degree-first and high-betweenness-first methods. Due to the strongly improved traffic capacity, this work may be helpful to design and optimize the structures of various communication networks.
