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.
