摘　　要：无线传感器网络(WSNs)由于受到资源与能量限制,能效与抗毁性成为WSNs拓扑设计的关键问题。借助无标度网络拓扑演化构建WSNs网络拓扑模型,提高网络的能效与抗毁性,从而最终延长WSNs的生存周期。根据现有模型,提出一种基于BA无标度网络的WSNs异质化演化模型,该模型具有BA无标度网络良好的随机抗毁性,同时拥有较好的蓄意攻击抗毁性。利用NetworkX仿真软件进行对比仿真实验,结果表明,该网络模型在蓄意失效部分节点时,相较于EAEM模型,基本无多余节点失效,且网络生命周期提升了10%左右。In the large-scale wireless sensor network(WSNs),the energy efficiency and invulnerability of the network become the key issues in the topology design of WSNs due to the resource and energy limitations and unattended characteristics.In this paper,scale-free network topology is used to construct a WSNs network topology mocel to improve the energy efficiency and invulnerability of the network.Based on the principles and concepts of complex networks,a heterogeneous evolution model of WSNs based on BA scale-free networks is proposed,which has good random attack invulnerability of BA scale-free networks and good deliberate attack in⁃vulnerability.Comparative simulation experiment with Networkx simulation software showed that the proposed network model has no ex⁃cess node failure compared to the EAEM model when deliberately failed,and the network life cycle is increased by about 10%.
