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.
An important design goal of wireless sensor networks is network reliability, limited wireless sensor network conditions, limited energy resources and poor arrangement environment, which make it crucial to study the node importance and survivability of wireless sensor networks. Energy will have an impact on network lifetime, and the same node location in the topology will also affect the network of various indicators.By studying the remaining energy nodes and nodes in the topology of the contribution, the combination of these two factors, the proposed calculation Node importance and network invulnerability. The simulation results and comparison show that the method is effective and the algorithm is not complicated.
