基于带内无线回程的HetNets安全性能研究
|
摘要
为解决当前异构网络物理层安全性能低下的问题,提出一种带内全双工(IB-FD)无线回程方案。在大规模多入多出(MIMO)双层HetNets中,宏蜂窝和小蜂窝通信链路受恶意窃听者窃听,将无线回程信号作为宏蜂窝与小蜂窝通信的干扰信号,以增强通信链路质量。借助随机几何与概率统计工具,将网络节点分别建模为齐次泊松点过程,研究宏蜂窝下行和小蜂窝上行传输的安全概率。研究结果表明,在大规模MIMO双层HetNets中,将IBFD无线回程信号作为一种干扰信号,宏蜂窝下行和小蜂窝上行链路的安全概率得到有效提高,且物理层安全性能优于带外全双工无线回程方案。
In order to solve the problem of low physical layer security performance in heterogeneous networks, an InBand Full-Duplex( IB-FD) wireless backhaul scheme is proposed. In massive Multiple Input Multiple Output( MIMO)two-tier HetNets,macro and small cell links are eavesdropped by malicious eavesdroppers,and the wireless backhaul signal is regarded as the interference signal for macro and small cell communications to enhance communication link quality. By using the tool of stochastic geometry and probability statistics,we modeled the network elements as independent Poission point processes, and investigate the secrecy probability of the macro cell downlinks and small cell uplinks. The presented results show that in massive MIMO HetNets, exploiting the IB-FD wireless backhaul signal as the interference can enhance the secrecy probabilities of both the macro and small cell transmission,and the in-band fullduplex backhaul mode outperforms the out-band Full-Duplex( FD) one.
