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 nodespsila 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.
