    Secrecy Cognitive Gain of Cognitive Radio Sensor Networks with Primary Outage Constraint by Hongyu Ma, Kai Niu, Weiling Wu, Shengyu Li, Guangqian Chu

    Published 2015-06-01
    “…This paper studies the physical layer security issue for cognitive radio sensor networks (CRSNs) with primary outage constraint, for which a tractable framework is developed to analyze the secrecy performance for CRSNs related to the random channel characteristics, the spatial distributions of nodes, the nearest neighbour routing protocol, and the aggregate interference. Based on stochastic geometry technique, a novel random analysis method is proposed to derive the closed-form expression of secrecy transmission capacity and analyze the connection outage probability (COP) and secrecy outage probability (SOP) for both secondary (SR) and primary (PR) systems. …”

    Cooperation in the face of crisis: effect of demographic noise in collective-risk social dilemmas by José F. Fontanari

    Published 2024-11-01
