N2 - Due to its high spectrum efficiency, strong ability to resist multipath fading, OFDM networks is widely applied in various wireless communication systems. However, physical layer security is also an important problem in OFDM networks. By using relay nodes, the secrecy outage probability can be reduced since relay nodes could increase freedoms of optimization for the cooperative OFDM networks. By optimizing multiple variables, which includes adaptive hybrid relaying scheme, relay selection, and resource allocation, we propose the secure algorithm which aims at minimizing the secrecy outage probability of multiuser in cooperative OFDM networks. To achieve this goal, we establish an optimization problem including multiple optimization variables. Then, we convert the optimization problem into a graph theory problem. Simulation results show that the secure algorithm can significantly reduce the secrecy outage probability of multiuser in cooperative OFDM networks.
