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 source-destination pair scheduling(RSDS)and the conventional non-cooperation(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.
为了增强无线异构网络中数据传输的物理层安全性能, 采用了一个基于两阶段传输的协作框架.在传输时隙开始时, 一个源节点-目的节点对将会被机会式选择, 并被用于辅助其他源节点-目的节点对传输数据.在该协作框架下, 提出了一种发射天线选择辅助的源节点-目的节点对调度方案, 并分析了该方案、传统源节点-目的节点对轮询调度方案及传统非协作方案的窃听概率, 其中传统轮询调度方案和非协作方案被用于与所提发射天线选择辅助的源节点-目的节点调度方案进行对比.数值结果表明, 增加源节点-目的节点对的数量可以有效降低所提方案的窃听概率, 而传统轮询调度方案和非合作方案的窃听概率随着源节点-目的节点对数量的增加而没有变化.此外, 所提方案能够比轮询调度方案和非合作方案取得更低的窃听概率, 显示了所提方案的优越性.
