Abstract: In the future wireless communication networks, the performance in cooperative communication depends on careful resource allocation such as relay selection and power control. In this paper, we propose a distributed buyer and seller gametheoretical framework over multi-user cooperative communication networks to achieve optimal relay selection and power allocation based on users link quality requirement. The power of the source nodes and relay nodes are jointly considered to benefit the utilities of source nodes and the relay nodes in this paper. The proposed approach not only helps the source find the relays at relatively better locations and allocates an optimal amount of power among the source node and the relays for minimization the source nodes payment, but also helps the competing relays maximize their own utilities by asking the optimal prices. Furthermore, the optimal prices can be decided by the local channel state information (CSI) and price per unit power of other relays. If the total number of available relay nodes increases, the energy consumption of the whole networks can be decreased.
