In this paper, we propose and analyze two important secure performance metrics of cluster-based multi-hop relay networks with friendly jamming nodes under the presence of multi-eavesdroppers in condition of imperfect channel estimation. At each hop, partial relay and jammer selection are used to improve the network security. The close-form expressions of secrecy outage probability and the probability of non-zero secrecy capacity of the considered system are derived as criteria to evaluate system security performance. The system performance is analyzed for Rayleigh fading channels with imperfect channel state information. Monte Carlo simulations are also performed to verify the correctness of the analytical results.

在本文中，我们提出并分析了在信道估计不完善的情况下，在存在多个监听器的情况下，具有友好干扰节点的基于集群的多跳中继网络的两个重要安全性能指标。在每个跃点处，使用部分中继和干扰选择来提高网络安全性。得出所考虑系统的保密中断概率和非零保密容量概率的近似表达式，作为评估系统安全性能的标准。分析具有不完善信道状态信息的瑞利衰落信道的系统性能。还执行了蒙特卡洛模拟，以验证分析结果的正确性。
