无线异构网络中基于传输节点对调度的物理层安全增强方法
Physical-layer security enhancement method for wireless HetNets via transmission pair scheduling
摘要
Abstract
In order to enhance the physical-layer security of wireless transmission in a wireless heterogeneous network (HetNet),a two-stage-based cooperative framework is advocated.To be specific,a source-destination (SD) pair is opportunistically chosen at the beginning of the transmission slot,which can be used to assist the transmissions of other SD pairs.Under this framework,a transmit antenna selection assisted opportunistic SD pair scheduling (TAS-OSDS)scheme is proposed,and the intercept probability (IP) of the proposed TAS-OSDS,the conventional round-robin sourcedestination pair scheduling (RSDS) and the conventional noncooperation (non-coop) schemes is also analyzed,where the RSDS and non-coop schemes are used for comparison with the proposed TAS-OSDS.Numerical results show that increasing the number of the SD pairs can effectively reduce the IP of the TAS-OSDS scheme,whereas the IP of the RSDS and the non-coop remain unchanged with an increasing number of the SD pairs.Furthermore,the TAS-OSDS scheme achieves a lower IP than that of the RSDS and the non-coop schemes,showing the superiority of the proposed TAS-OSDS.关键词
