Abstract

Abstract—In this paper, the case of one source-destination pair with the help of multiple cooperating nodes in the presence of one eavesdropper was considered to improve the performance of secure wireless communications. A novel cooperative scheme decode-and-forward plus cooperative jamming(DFCJ) was proposed. In this scheme, the relay nodes transmit a weighted version of the source signals plus a common weighted jamming signal to confound the eavesdropper. For DFCJ, the optimal power allocation is obtained in closed-form in the condition of the complete nulling of jamming signals at the destination subject to a secrecy rate constraint. The numerical evaluation of the transmit power and the obtained secrecy rate results shows that the proposed scheme can significantly improve the performance of wireless physical layer security, as compared to the decodeand- forward(DF) scheme.
