由于无线传感网中的传感节点受限于计算能力,电源能量、以及存储空间,如何确保无线传感网络的通信安全成为亟待破解的研究难点。基于此,旨在探讨如何应用压缩感知技术来保障无线传感网络的通信安全,针对放大转发式压缩感知技术下的无线传感网络安全问题给出了安全可靠的通信信号重构算法,并且推导得到了压缩感知保密技术下的保密容量门限值。另外给出了无线传感网络不同节点参数条件下的无线传感网络保密容量的定量化分析。仿真结果进一步验证了所提安全通信方案的有效性。
As sensing nodes in WSN are limited by computing power, power energy and storage space, how to ensure the communication security of WSN becomes a research difficult to be solved urgently. Based on this, this paper aims to explore how to apply compressed sensing technology to secure the communication of wireless sensor networks. A reliable and reliable communication signal reconstruction algorithm is proposed for the security of wireless sensor networks under the amplification and forwarding compression sensing technology. The threshold of confidential capacity under the compression-aware security technology is obtained. In addition, the quantitative analysis of WSN confidentiality capacity under different node parameters of wireless sensor network is given. Simulation results further verify the effectiveness of the proposed secure communication scheme.
