Simultaneous Energy Harvesting and Sender-Node Authentication at a Receiver Node

摘要: We consider a system with three single-antenna nodes; Alice talks to Bob over time-slotted AWGN channel, while Eve's objective is impersonate Alice. then setting where, for every received packet, needs do simultaneous energy harvesting (EH) and sender-node authentication. To this end, employs {\it frequency offset} as the decision metric binary hypothesis testing based authentication framework. Then, assuming separate receive chains information decoding, implements two deterministic} schemes: i) time-switching (TS) based, ii) static power-splitting (SPS) based. For both EH schemes, we analyze trade-off between detection performance of scheme amount harvested. Numerical results suggest that same performance, SPS outperforms TS in terms also random} scheme, so-called opportunistic whereby utilizes packets (as labeled by scheme) harvest energy. There, it straightforward see normalized mean throughput chain increases linearly an increase attack rate.
