本文基于物理层安全技术，研究了无线自组网中的安全最优QoS路由问题。具体来说，我们考虑一个多跳WANET与恶意窃听和合作干扰，制定SOQR作为一个优化问题。为了解决这个问题，我们首先推导出封闭形式的表达式的连接中断概率（COP）和保密中断概率（SOP）的任何给定的端到端路径，作为通信QoS和传输安全的性能指标，分别。然后，我们探讨了最小COP的条件下，SOP是低于一个预先指定的阈值，并得到相应的可实现的功率分配策略。通过对给定路径的分析，进一步提出了SOQR算法，该算法以分布式的方式选择源节点和目的节点之间的安全路径，以达到最优的QoS性能。最后，数值模拟进行验证我们的理论结果的效率，以及说明QoS安全权衡。
This paper study the secure optimal QoS routing (SOQR) in wireless ad hoc networks (WANETs) based on the physical layer security techniques. Specifically, we consider a multi-hop WANET with malicious eavesdroppers and cooperative jammers, and formulate the SOQR as an optimization problem. To deal with this problem, we first derive the closed-form expressions of connection outage probability (COP) and secrecy outage probability (SOP) for any given end-to-end path, which serve as the performance metrics of communication QoS and transmission security, respectively. Then, we explore the minimum COP conditioned on that SOP is below a pre- specified threshold and obtain the corresponding achievable power allocation strategy. With the help of analysis of a given path, we further propose the SOQR algorithm which selects the secure path between a pair of source and destination nodes in a distributed manner to achieve the optimal QoS performance. Finally, numerical simulations are conducted to validate the efficiency of our theoretical results, as well as to illustrate the QoS-security tradeoffs.
