Cooperative system is a promising concept to improve the performance of the communication in wireless networks. This new paradigm of wireless communication imposes new challenges to traditional problems such as resource allocation. To model the behaviors of selfish and autonomous nodes in a cooperative system, game theory is an appropriate tool. This thesis focuses on power allocation in wireless cooperative systems based on game theory, with three research components.
First, we study the power allocation in multi-user relay networks with altruistic relays. We propose an asymmetric Nash bargaining solution-based relay power allocation scheme, which can achieve a balance between global network performance and user fairness. We also give a distributed implementation of the proposed scheme. Second, we consider the power allocation and relay cooperation stimulation problem in multi-user relay networks. We use Stackelberg game to analyze the interaction between the relays and the users. Based on the proposed fair relay power allocation rule, the optimal relay power price is derived analytically. Third, we study the power allocation and user cooperation stimulation problem in multi-user cooperative networks. We propose an iterative double auction-based power allocation algorithm. We show that this algorithm achieves global optimality in the sense of weighted sum-signal-to-noise ratio.
