无标度网络中非均匀选择源和目的地数据包的流量动力学
Traffic dynamics of packets generated with non-homogeneously selected sources and destinations in scale-free networks
摘要：
在本文中，我们研究了无标度网络中的流量动力学，其中数据包产生与非均匀选择的源和目的地，并根据本地路由策略转发。我们考虑了两种情况下的数据包生成：（i）数据包更有可能在高度节点生成;（ii）数据包更有可能在低度节点生成。类似地，我们考虑两种情况下的数据包目的地：（a）数据包更有可能去高度节点;（b）数据包更有可能去低度节点。仿真结果表明，网络容量和最大网络容量所对应的最优$α$值很大程度上取决于数据包源和目的地的配置。特别地，当大多数分组从低度节点行进到高度节点时，容量大大增强。
英文摘要：
In this paper, we study traffic dynamics in scale-free networks in which packets are generated with non-homogeneously selected sources and destinations, and forwarded based on the local routing strategy. We consider two situations of packet generation: (i) packets are more likely generated at high-degree nodes; (ii) packets are more likely generated at low-degree nodes. Similarly, we consider two situations of packet destination: (a) packets are more likely to go to high-degree nodes; (b) packets are more likely to go to low-degree nodes. Our simulations show that the network capacity and the optimal value of $α$ corresponding to the maximum network capacity greatly depend on the configuration of packets' sources and destinations. In particular, the capacity is greatly enhanced when most packets travel from low-degree nodes to high-degree nodes.
