A distributed power control algorithm in hybrid cellular and Peer-to-Peer(P2P) network is proposed.In the objective of overall system spectrum efficiency maximization,a distributed power control scheme of P2P transmission in the hybrid system model is devised based on the tools of convex optimization.The algorithm considers the harmful interference between cellular sub-system and P2P sub-system,and provides effective interference avoidance mechanism,thus improves the total system throughput.Simulation results prove the convergence and performance of the proposed scheme.
