摘　　要：无标度网络具有场景适应性强,且应对随机性打击效果较好等特点。为提高无线传感器网络的抗毁性能,从网络拓扑演化角度入手,构建具有无标度特性的网络拓扑。结合无线传感器网络中每个节点都有其通讯范围的特点,将无标度网络引入到无线传感器网络,且在择优演化过程中,各节点度不得超过设定值,构建基于无标度局域世界演化网络模型的无线传感器网络拓扑,并对模型进行仿真。从结果可明显看出,优化的模型中连边较短,即优化的模型平均最短路径降低,可有效减少数据收发过程中能量的消耗,延长网络生存周期,提高网络抗毁性。The scale-free network has the properties of strong scene adaptability and good ability against random attack. In order to improve the invulnerability of wireless sensor networks, a scale-free network is constructed from the perspective of topology evolution. Combining the property of each node in WSNs having its own communication range, the scale-free network is introduced into the WSNs. The WSN topology based on the scale-free local world evolution network model is constructed in the optimal evolution process with the degree of each node not exceeding the set value, and the WSN topology model is simulated. From the results of the graphs and data, it can be seen clearly that the connected edges in the optimized model are shorter. That is, the average shortest path of the optimized model is reduced, which can reduce the energy consumption effectively during data transmission and reception, prolong the network life cycle and improve the network invulnerability.
