基于新局域世界的BBV网络模型演化研究

在BBV加权无标度模型演化过程中，节点加入时选取的是整个网络，而实际复杂网络中只有小部分节点能够获得全局网络的信息，大部分节点只能获取局部网络的信息。针对该问题，提出一个新局域的BBV加权网络模型，将新局域世界模型引入BBV模型中。理论分析及仿真实验结果表明，该模型节点强度具有幂律分布的特性，且幂律指数可以通过参数的修改在区间1,3]内进行调节。

Research on BBV Network Model Evolving Based on New Local-world

In the process of BBV weighted scale-free network evolving, the new nodes obtain the entire networks when the new nodes are added to networks. But in some real complex networks, only a few nodes can obtain the global information, most of the nodes own only obtain local information of the networks. The new local-world model is introduced into BBV, and the new local-world BBV weighted network model is proposed. According to theoretical analysis, the strength of nodes of this network model obeys power-law, and the exponent of power-law can be adjusted between 1 and 3 through controlling the parameters. Furthermore, the results of the simulation are in agreement with the theoretical analysis.
