In this paper, the optimal power control problem in a cooperative relay network is investigated and a new power control scheme is proposed based on a non‐cooperative differential game. Optimal power allocated to each node for a relay is formulated using the Nash equilibrium in this paper, considering both the throughput and energy efficiency together. It is proved that the non‐cooperative differential game algorithm is applicable and the optimal power level can be achieved.
