Secrecy analysis in Simultaneous Wireless Information and Power Transfer (SWIPT) Systems over generalized k-fading channels
Abstract
This project investigates the secrecy performance of
Simultaneous Wireless Information and Power
Transfer (SWIPT) systems over generalized-K fading
channels, which model both small-scale and large
scale fading effects critical to real-world wireless
environments. Ensuring data confidentiality in
SWIPT systems is increasingly essential due to the
risk of eavesdropping during concurrent power and
information transfer. The analysation of the secrecy
outage probability (SOP) and effective secrecy
throughput (EST) under various channel conditions,
providing closed-form expressions for SOP and
examining its behaviour in both typical and
asymptotic signal-to-noise ratio (SNR) regions.
Additionally, it derives diversity orders for high-SNR
regimes, offering a clearer understanding of SOP as
influenced by factors like channel quality, fading
severity, and eavesdropper capabilities. To further
assess secrecy, examination of time-switching
protocols within SWIPT, highlighting trade-offs in
power and information flow is done. Numerical
simulations confirm the accuracy of our analytical
models, demonstrating that system security in SWIPT
can be optimized through strategic parameter
tuning.
Effective secrecy throughput is also investigated to
capture
the
amount of secure transmitted
information. To derive the diversity order, the
asymptotic SOP is also analysed when the average
signal-to-noise ratio is large sufficiently. Finally,
numerical results are used to validate the
correctness of our derived expressions
