Abstract
AbstractInternet of Things (IoT) environments are comprised of a variety of electronic objects that transmit radio frequency (RF) signals. It further introduces the enticing possibility of using pre-existing signals for a variety of applications, including medical, industrial, and home automation. This work examines the secrecy performance of an RF-based IoT network in the presence of an eavesdropper (ED) located in a close communication range. It is considered that ED is attempting to wire-tap the secret information by having random waypoint (RWP) mobility in a communication range. Further, the novel analytical expressions for secrecy outage probability (SOP) and probability of strictly positive secrecy capacity (SPSC) in terms of Meijer’s-G function are derived. Finally, to obtain a better understanding of the system’s performance, the analytical results are expressed asymptotically in the high signal-to-noise ratio (SNR) regime and verified with analytical results.KeywordsProbability of SPSCRWP mobilitySOP
