Multi-user Power Allocation for Multi-service Transmission in Cooperative Communication Networks Based on Stackelberg Game

In this paper the game-theoretical is introduced into the multi-user power allocation in cooperative communication networks. We firstly divide the users into two groups that are users of real-time service and non-real-time service. We analyze the optimal power allocation for multi-service transmission; demonstrate the relationship between the two types of services. Then a bilevel programming model based on Stackelberg game is designed and a chaotic optimization algorithm is given. Finally, we present the simulation results of the optimal power allocation.
