In a cooperative relay scenario with multiple spectrum bands, modelling the nodes of a network as energy sellers, a joint power and channel allocation scheme based on energy pricing is proposed for parallel-transmission to extend the lifetime of the cooperative network by considering variant transmit power and spectrum availability. The optimal power allocation solutions between the source node and the relay node are obtained by a dual-based optimal power schedule algorithm, and the end-to-end throughput of parallel-transmission is fulfilled with minimum system cost (MSC) criteria. The superiority of the MSC scheme over other schemes has been verified by quantitative results.
