无线网络中的平均场能量博弈

Mean Field Energy Games in Wireless Networks

François Mériaux, Vineeth Varma, Samson Lasaulce

摘要:

这项工作解决的问题,能源效率的分布式功率控制在无线网络中有大量的发射机。这个问题是由一个动态博弈模型。每个发射机-接收机通信的特征在于由可用能量和/或单个信道状态给出的状态,并且其演变由某些动态支配。由于在这样一个(随机)游戏的均衡分析通常是困难的,甚至是不可能的,这个问题是近似利用大系统的假设。在一个适当的交换假设下,相应的平均场博弈得到了很好的定义,并详细研究了特殊情况。这项工作的主要贡献是显示如何平均场游戏可以应用到调查中的问题,并提供说明性的数值结果。我们的研究结果表明,这种方法可以导致显着的收益,在能源效率方面,在所产生的平衡。

英文摘要:

This work tackles the problem of energy-efficient distributed power control in wireless networks with a large number of transmitters. The problem is modeled by a dynamic game. Each transmitter-receiver communication is characterized by a state given by the available energy and/or the individual channel state and whose evolution is governed by certain dynamics. Since equilibrium analysis in such a (stochastic) game is generally difficult and even impossible, the problem is approximated by exploiting the large system assumption. Under an appropriate exchangeability assumption, the corresponding mean field game is well defined and studied in detail for special cases. The main contribution of this work is to show how mean field games can be applied to the problem under investigation and provide illustrative numerical results. Our results indicate that this approach can lead to significant gains in terms of energy-efficiency at the resulting equilibrium.
