摘要
从特定的以数据为中心的无线传感器网络拓扑结构出发,首先给出了无线传感器网络连通性的一个新测度—连通系数,在此基础之上给出了抗毁性测度的新定义,针对面临的两种攻击,给出了无线传感器网络抗毁性的两个新测度-容错度和抗攻击度,并对基于小世界模型的无线传感器网络抗毁性进行了抗毁性分析,仿真表明提出的评估模型更能客观,准确地评估以数据收集为中心的无线传感器网络的抗毁性。
In this paper,a new measure of wireless sensor network connectivity is proposed based on the characteristics of the data collecting network. A new definition of invulnerability is proposed,and two measures of invulnerability are proposed for the two different damages. At last,this paper studies the invulnerability of the wireless sensor networks based on the small-world model. The simulation indicates that it is a new and effective method to research the invulnerability for the wireless sensor networks.
