中文摘要：
针对无线传感器网络抗毁性的问题，从复杂网络的视角提出了两个基于无标度网络的无线传感器网络拓扑演化模型。这两个演化模型先借助分簇算法实现传感器簇头的均匀分布，然后按照一定的连接策略，进行簇间的拓扑演化。根据提出的拓扑演化模型，设计了相应的拓扑演化算法，并对拓扑演化模型的动态特性进行了分析。仿真结果表明，由于新模型设计考虑了节点剩余能量、节点饱和度等问题，因此演化而成的网络拓扑更加符合无线传感器网络的实际应用，并且具有很好的抗毁性，进一步提高了网络的鲁棒性。
英文摘要：
In view of the survivabihty of wireless sensor networks （ WSNs）, two topology evolution models for WSNs based on a scale-free network are proposed from the angle of complex networks. The models firstly use a clustering algorithm to achieve the cluster heads, uniform distribution, and then make the topology evolution among cluster heads according to a certain connection strategy. The corresponding topology evolution algorithms are given accord- ing to the proposed models, and the dynamic characteristics of the models are analyzed. The simulation results show that the network topologies formed by the new models are more fit for the practical applications of WSNs and have a good survivability, a further improved robustness due to the consideration of the node residual energy and the node saturation when designing the models.
