Before revision:  As a step to address these issues, this paper explores the physical layer security-aware routing and performance tradeoffs in a multi-hop WANET . Specifically, for any given end-to-end path in a general multi-hop WANET, we first derive its connection outage probability (COP) and secrecy outage probability (SOP) in closed-form, which serve as the performance metrics of communication QoS and transmission security, respectively.
