| 摘 要： | 无线传感器网络的一个重要设计目标是网络可靠性,无线传感器网络条件受限,节点能源有限,布置环境恶劣,使得研究无线传感器网络的节点重要性和抗毁性变得至关重要.节点的剩余能量会对网络生存时间产生影响,同样节点在拓扑结构中的位置也会对网络各个指标产生影响.通过研究节点的剩余能量和节点在拓扑结构中的贡献,综合这两种因素,提出了计算节点重要性和网络抗毁性的方法.仿真结果及对比表明该方法效果较好,且算法并不复杂.

| Abstract: | The reliability of the wireless sensor networks is one of key goal of system design.The condition of wireless sensor networks is extremely limited,the energy of the nodes are restricted,the environment where the nodes are layout is poor,so the survivability of wireless sensor networks is vital for the lifetime of the networks,and also is the importance of the nodes.Residual energy of node of the network is one of key factors influencing the networks' survival time,and also is the node's position in the topo... |
