Abstract—A pricing game is derived for cooperative transmission among selfish nodes. Each source node is assigned an orthogonal channel. By overhearing other channels, the source nodes can help relaying other nodes ’ messages at a rate based on the received payments. At Nash Equilibrium, the total transmission power is minimized. We also propose a simplified implementation for low rate regime. Simulation results illustrate the significant improvement of power consumption over direct transmission scheme and the high convergence rate of our implementation. I
