| 摘要: |
| 抗毁性是评价无线传感网络拓扑结构的重要性能之一,如何构建一个健壮的网络显得尤为重要.基于复杂网络理论,提出一种关于节点度、剩余能量、传输距离的网络演化模型,简称DEDA.同时引入了几种适合无线传感网络的指标来评价网络的抗毁性.利用计算机仿真技术,比较了不同模型演化所形成的网络拓扑结构在随机和故意攻击下的抗毁性.实验结果表明,DEDA模型演化形成的无线传感网络在随机攻击和故意攻击下提供了更好的抗毁性. |

| Abstract: |
| Resilience has become one of the most important indicators in evaluating the topological structure of wireless sensor networks. How to construct a robust topology of WSNs is even more important. Based on complex networks theory, a topology evolution model—DEDA, which considers the node degree, the remaining energy and the transmission distance, is proposed. Some resilience metrics are introduced to analyze the resilience of WSNs and computer simulations are performed to compare the resilience of several topologies that are generated with different growth models. The experimental results show that DEDA model provides better resilience against both random and deliberate attacks. |
