Security–Reliability Tradeoff Analysis for SWIPT- and AF-Based IoT Networks With Friendly Jammers

Radio-frequency (RF) energy harvesting (EH) in wireless relaying networks has attracted considerable recent interest, especially for supplying to relay nodes the Internet of Things (IoT) systems assist information exchange between a source and destination. Moreover, limited hardware, computational resources, availability IoT devices have raised various security challenges. To this end, physical-layer (PLS) been proposed as an effective alternative cryptographic methods providing security. In study, we propose PLS approach simultaneous power transfer (SWIPT)-based half-duplex (HD) amplify-and-forward (AF) presence eavesdropper. Furthermore, take into account both static splitting (SPSR) dynamic (DPSR) thoroughly investigate benefits each one. further enhance secure communication, consider multiple friendly jammers help prevent wiretapping attacks from More specifically, provide reliability analysis by deriving closed-form expressions outage probability (OP) intercept (IP), respectively, SPSR DPSR schemes. Then, simulations are also performed validate our effectiveness Specifically, numerical results illustrate nontrivial tradeoff system. addition, conclude simulation that scheme outperforms SPSR-based terms OP IP under influences different parameters on system performance.
