集成静态和动态信息以路由流量
Integrating static and dynamic information for routing traffic
摘要:
复杂网络中流量路由的效率可以通过两个关键指标来反映,即系统容量和数据包平均传输时间。在本文中,我们提出了一种混合路由策略,通过整合本地静态和动态信息,以提高效率的流量在无标度网络。该策略由一个参数控制。仿真结果表明,在同时考虑网络容量最大化和减少数据包传输时间的情况下,存在一个最优参数值。与采用局部静态信息的策略相比,该策略在提高系统效率方面具有明显的优势。详细分析了混合策略。研究表明,如何有效地利用度较大的节点在无标度交通系统中起着关键作用。
英文摘要:
The efficiency of traffic routing on complex networks can be reflected by two key measurements i.e. the system capacity and the average data packets travel time. In this paper, we propose a mixing routing strategy by integrating local static and dynamic information for enhancing the efficiency of traffic on scale-free networks. The strategy is governed by a single parameter. Simulation results show that there exists a optimal parameter value by considering both maximizing the network capacity and reducing the packet travel time. Comparing with the strategy by adopting exclusive local static information, the new strategy shows its advantages in improving the efficiency of the system. The detailed analysis of the mixing strategy is provided. This work suggests that how to effectively utilize the larger degree nodes plays the key role in the scale-free traffic systems.
