摘要
为了加强电力隧道内的无线网络安全通信,文中提出了基于双向中继网络安全的通信传输方案。构造了由两个信源、多个协作中继和一个干扰器组成的双向中继网络模型,利用放大转发协议来最大化信源之间的转发信号,并且剩余的中继节点通过分布式波束形成传输干扰信号,以此混淆干扰器信号源。实验结果表明:随着发射功率的增加,所提方案的保密中断概率收敛到零。
In order to strengthen the wireless network security communication in power tunnel,a communication transmission scheme based on two-way relay network security is proposed,which consist of two sources,multiple cooperative relays and one eavesdropper.The amplification and forwarding protocol is used to max-imize the forwarding signals between sources,and the remaining relay nodes transmit interference signals through distributed beamforming to confuse the eavesdropper signal sources.The experimental results show that the proposed scheme converges to zero with the increase of transmission power.
