Query: Physical Layer Security-Aware Routing and Performance Tradeoffs in Ad
  Hoc Networks   The application of physical layer security in ad hoc networks has attracted
considerable academic attention recently. However, the available studies mainly
focus on the single-hop and two-hop network scenarios, and the price in terms
of degradation of communication quality of service (QoS) caused by improving
security is largely uninvestigated. As a step to address these issues, this
paper explores the physical layer security-aware routing and performance
tradeoffs in a multi-hop ad hoc network. Specifically, for any given end-to-end
path 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. Based on the
closed-form expressions, we then study the security-QoS tradeoffs to minimize
COP (resp. SOP) conditioned on that SOP (resp. COP) is guaranteed. With the
help of analysis of a given path, we further propose the routing algorithms
which can achieve the optimal performance tradeoffs for any pair of source and
destination nodes in a distributed manner. Finally, simulation and numerical
results are presented to validate the efficiency of our theoretical analysis,
as well as to illustrate the security-QoS tradeoffs and the routing
performance.
