This article proposes a cooperative friendly jamming framework for swarm unmanned aerial vehicle (UAV)-assisted amplify-and-forward (AF) relaying networks with wireless energy harvesting. Due to the limited of UAVs, we develop collaborative time-switching protocol which allows UAVs collaborate harvest energy, relay information, and jam eavesdropper. To evaluate secrecy rate, derive outage proba...

Non-orthogonal multiple access (NOMA) has been envisioned as a promising technique to improve spectral efficiency and provide massive connectivity in future wireless networks. However, the inherited security issues with NOMA should be carefully addressed further exploit its potential benefits enabled As such, we consider cooperative network, where source uses simultaneously communicate multi-an...
