摘要：in this study, the authors investigate the security and reliability trade-off (srt) performance of a multiuser wireless network, where an eavesdropper attempts to overhear the confidential transmissions between a base station and multiple users under the impact of co-channel interference. to enhance the srt performance of the network, the authors propose two joint user and jammer selection schemes, namely the joint optimal user and random jammer selection (jou-rjs) scheme and the joint optimal user and optimal jammer selection (jou-ojs) scheme. for srt performance comparison purposes, the traditional multiuser scheduling (tmus) scheme is also considered. the authors derive closed-form outage and intercept probability expressions for the jou-rjs and jouojs schemes. simulation results show that the srts of both jou-rjs and jou-ojs schemes are better than that of the tmus scheme, where jou-ojs achieves the best srt performance. additionally, this study also shows that an expected outage or intercept probability of the tmus, jou-rjs, and jou-ojs schemes can be achieved by giving an appropriate overall rate. finally, the sum of the outage and intercept probability can be minimised through an optimal power allocation between the selected user and friendly jammer for the proposed jou-rjs and jou-ojs. © the institution of engineering and technology 2019.
