中文摘要
      如何通过合理构建拓扑模型有效提高网络抵御攻击的能力, 一直是该领域研究的热点之一. 针对无线传感 网络无标度拓扑在遭受不同攻击方式时抗毁性差的问题, 本文结合节点出入度和介数中心性两种因素, 同时考虑数 据传输的有向性, 提出衡量网络抗毁性的度量模型概念, 将该模型引入择优连接概率中, 构建具有抗毁性的无线传 感器网络有向拓扑模型. 理论证明网络节点出入度均服从幂律分布, 符合无标度特性, 仿真实验结果表明, 在相同实 验环境下, 该文所构拓扑模型在最大连通分支比例和网络效率两方面均优于其他3种比较模型, 具有更强的抗毁性.
英文摘要
      How to improve the ability of network to resist attacks effectively by constructing the topology model is one of the research hotspots in this field. Scale-free topology for wireless sensor network in different attack ways problem of anti-destroying ability is poor, and combining with node discrepancy degree and betweenness centrality, two factors have to consider the data transmission at the same time, put forward the measure of network anti-destroying ability measurement model concept, introducing the model merit connected probability, build an anti-destroying ability of wireless sensor network has to the topology model.It is proved theoretically that the network node access degree obeys power law distribution and conforms to scale-free characteristics. The simulation results show that the topology model proposed in this paper is superior to the other three comparison models in terms of the maximum connected branch ratio and network efficiency under the same experimental environment, and has stronger destruction resistance.
