Query: Secrecy Outage for Wireless Sensor Networks   This paper addresses Physical Layer Security (PLS) for a wireless sensor
network in which multiple sensor nodes communicate with a single sink in the
presence of an eavesdropper. Under the assumption of sink using outdated
channel state information (CSI) of the eavesdropper link, the outage
probability of achievable secrecy rate under Weibull fading is investigated and
its analytical expressions are derived. Specifically, we consider sensor
scheduling to enhance PLS, thereby we quantify the degradation in outage
probability due to outdated CSI under the best-node scheduling scheme and
compare it with conventional round-robin scheduling. Finally, we analyze
secrecy outage probability conditional on successful transmission and provide
practical insights into the effect of outdated CSI of the eavesdropper. The
derived theoretical results are validated through simulations.
