Abstract

The wireless revolution requires future wireless networks the capability of intelligently optimizing the spectrum by collaborating and using autonomy to determine not just the best use of the spectrum for its own system, but the best use of spectrum for other systems that share the same spectrum bands. How to develop the wireless paradigm of collaboration, therefore, is a crucial question. In this paper, we discuss how to model collaborative power control in a wireless interference network, where users share the same frequency band. By collaborating with other users, each user exchanges information to maximize not only its own performance but also others’ performances. A game theory framework is developed to determine the optimal power allocation. The proposed framework possesses several advantages over conventional methods, such as low complexity and fast converging algorithmic solutions, distributed implementation, and better user fairness. Simulation results state the proposed approach provides better fairness between users’ data rates, higher performance in the aggregate rate, and lower convergence time.

无线网络中协作和分布式功率控制的博弈论范式
无线革命要求未来的无线网络具备智能优化频谱的能力,通过协作和自主使用,不仅为自己的系统确定频谱的最佳用途,而且为共享相同频段的其他系统确定频谱的最佳用途。因此,如何发展无线协作模式是一个关键问题。在本文中,我们将讨论如何在用户共享同一频段的无线干扰网络中建立协作功率控制模型。通过与其他用户协作,每个用户都会交换信息,不仅使自己的性能最大化,也使其他用户的性能最大化。本文提出了一个博弈论框架来确定最佳功率分配。与传统方法相比,所提出的框架具有若干优势,如复杂度低、算法解决方案收敛快、分布式实施以及更好的用户公平性。仿真结果表明,所提出的方法能更好地实现用户数据速率之间的公平性、更高的总速率性能和更短的收敛时间。

期刊介绍: Annals of Telecommunications is an international journal publishing original peer-reviewed papers in the field of telecommunications. It covers all the essential branches of modern telecommunications, ranging from digital communications to communication networks and the internet, to software, protocols and services, uses and economics. This large spectrum of topics accounts for the rapid convergence through telecommunications of the underlying technologies in computers, communications, content management towards the emergence of the information and knowledge society. As a consequence, the Journal provides a medium for exchanging research results and technological achievements accomplished by the European and international scientific community from academia and industry.
