Traffic dynamics of multilayer networks draws continuous attention from different communities since many systems are actually proved to have a multilayer structure. Since the core nodes of network are prone to congested, an effective routing strategy is of great significance to alleviate the congestion of the multilayer networks. In this paper, we propose an efficient improved routing strategy, with which the core nodes that can reasonably avoid congestion at the high-speed layer in the transmission process of packets, and can also make the most of the traffic resources of the low-speed layer nodes to optimize the traffic capacity of multilayer networks. The simulation results show that the proposed routing strategy can not only improve the network traffic capacity, but also shorten the average path length and average transmission time.

一种有效改进的多层网络路由策略

多层网络的流量动态引起了不同社区的持续关注，因为许多系统实际上被证明具有多层结构。由于网络的核心节点容易发生拥塞，有效的路由策略对于缓解多层网络的拥塞具有重要意义。在本文中，我们提出了一种高效的改进路由策略，核心节点在数据包传输过程中可以合理避免高速层的拥塞，同时也可以充分利用低速层的流量资源。层节点以优化多层网络的流量容量。仿真结果表明，所提出的路由策略不仅可以提高网络流量容量，而且可以缩短平均路径长度和平均传输时间。
