Downlink and Uplink Cooperative Transmission for Primary Secrecy Based Cognitive Radio Sensor Networks by Dawei Wang, Pinyi Ren, Qinghe Du, Li Sun, Yichen Wang

“…Aiming at allocating more licensed spectrum to wireless sensor nodes (SNs) under the constraint of the information security requirement of the primary system, in this paper, we propose a cooperative relaying and jamming secure transmission (CRJS) scheme in which SNs will relay primary message and jam primary eavesdrop concurrently with SN's downlink and uplink information transmission in cognitive radio sensor networks (CRSNs). In our proposed CRJS scheme, SNs take advantages of physical layer secure technologies to protect the primary transmission and acquire some interference-free licensed spectrum as a reward. …”
