Abstract

Most orthogonal frequency division multiplexing (OFDM) wireless communication system is poor in secure transmission. Based on user's physical layer security rate requirement, an OFDM system cooperative scheme over multi-relay cooperative communication networks to achieve optimal relay selection and power allocation was proposed in this paper. The proposed approach not only helps the source find the relays at relatively better locations, but also allocate an optimal amount of power among the relays for minimization the source node's payment. In this paper, the uniqueness of the solution was proved. The simulation results showed that although the physical layer security rate was zero while the source node was independent. But when the relay node helped it cooperate to transmit the data, the source node could obtain the physical layer security rate to meet the demand. Furthermore, the more the number of the relay nodes of the participating collaboration, the less the payment of the source node.
