TI  - Transmit Power Allocation for Physical Layer Security in Cooperative Multi-Hop 
      Full-Duplex Relay Networks.
LID - 1726
AB  - In this paper, we consider a transmit power allocation problem for secure 
      transmission in multi-hop decode-and-forward (DF) full-duplex relay (FDR) 
      networks, where multiple FDRs are located at each hop and perform cooperative 
      beamforming to null out the signal at multiple eavesdroppers. For a perfect 
      self-interference cancellation (PSIC) case, where the self-interference signal at 
      each FDR is completely canceled, we derive an optimal power allocation (OPA) 
      strategy using the Karush-Kuhn-Tucker (KKT) conditions to maximize the achievable 
      secrecy rate under an overall transmit power constraint. In the case where 
      residual self-interferences exist owing to imperfect self-interference 
      cancellation (ISIC), we also propose a transmit power allocation scheme using the 
      geometric programming (GP) method. Numerical results are presented to verify the 
      secrecy rate performance of the proposed power allocation schemes.
