Performance analysis of congestion-aware secure broadcast channels

Abstract Congestion-aware scheduling in case of downlink cellular communication has ignored the distribution diverse content to different clients with heterogeneous secrecy requirements. Other possible application areas that encounter preceding issue are secure offloading mobile-edge computing, and vehicular communication. In this paper, we extend work Arvanitaki et al. (SN Comput Sci 1(1):53, 2019) by taking into consideration congestion random access. Specifically, study a two-user congestion-aware broadcast channel traffic security We consider two randomized policies for selecting which packets transmit, one is queue size, whereas other congestion-agnostic. analyse throughput delay performance under decoding schemes at receivers, provide insights their relative how control holding confidential information can help decrease average per packet. show policy provides better delay, throughput, large arrival packet probabilities information. The derived results also take account self-interference caused receiver whom data intended due its full-duplex operation while jamming user. Finally, schemes, formulate our problems terms multi-objective optimization, allows finding trade-off between legitimate user policy.
