The achievable secrecy throughput of the Distributed Cognitive Radio Wireless Networks (DCRWNs) is investigated in this paper. The related works on the secrecy performance mainly focus on the average value depending on nodes spatial distribution. However, these results neglect the effect of nodes location on the performance discrepancies. To break this bottleneck, a new framework is developed to derive a closed-form expression of the achievable secrecy throughput for the secondary network under the outage constraint of the primary network.
