摘要
无线网络实现串行干扰消除算法可以提高网络吞吐量,在采用串行干扰消除算法的无线网络系统中,如何控制节点间传输功率使系统效用最大化是一个NP-Hard难题。针对此问题提出非合作博弈算法来解决节点间的传输功率控制,提出了串行干扰消除算法功率控制的非合作博弈,证明了纳什均衡,所提算法可以获得较高的无线网络吞吐量,仿真实验证实了分析结果并展示了算法的优越性。
It was proved that implementation of successive interference cancellation could improve network throughput in wireless networks, while in order to maximize network throughput, it was a NP-Hard problem that how to control transmission power when successive interference cancellation was used in wireless networks. A non-cooperative game theory is proposed to solve power control between wireless nodes for successive interference cancellation, in which non-cooperative game theory model is proposed and Nash equilibrium is analyzed, and also the proposed algorithm can obtain good network throughput than others, simulations validate the results and demonstrate the superiority of the algorithm.
