摘要
In this letter, we propose a relay selection and power allocation scheme for decode-and-forward (DF) cooperative network based on energy pricing. Modeling the nodes of the network as energy sellers, we can derive the optimal power allocation solution between the source node and the relay node by graphic method intuitively and select the optimal relay node according to minimum cost (MIC) criteria. Simulation results show that the lifetime of the cooperative network can be significantly prolonged using the proposed scheme compared with other schemes.
