基于多智能体强化学习的能量波束形成控制

Multiagent Reinforcement Learning based Energy Beamforming Control

Liping Bai, Zhongqiang Pang

摘要:

超低功率设备使远场无线功率传输成为能量输送的可行选择,尽管存在指数衰减。从站构造电磁波束,使得无线能量定向地集中在超低功率设备周围。能量波束形成由于缺乏对信道状态的反馈而面临着与信息波束形成不同的挑战。已经提出了各种方法,例如一比特信道反馈以提高能量波束形成能力,但它仍然具有相当大的计算开销,并且需要集中计算。宝贵的资源和时间被浪费在来回传输控制信息上。在本文中,我们提出了一种新的多智能体强化学习(MARL)制定基于码本的波束形成控制。它利用了无线供电网络中固有的分布式结构,并为完全本地计算的波束控制算法奠定了基础。源代码可以在https://github.com/BaiLiping/WirelessPowerTransfer上找到。

英文摘要:

Ultra low power devices make far-field wireless power transfer a viable option for energy delivery despite the exponential attenuation. Electromagnetic beams are constructed from the stations such that wireless energy is directionally concentrated around the ultra low power devices. Energy beamforming faces different challenges compare to information beamforming due to the lack of feedback on channel state. Various methods have been proposed such as one-bit channel feedback to enhance energy beamforming capacity, yet it still has considerable computation overhead and need to be computed centrally. Valuable resources and time is wasted on transfering control information back and forth. In this paper, we propose a novel multiagent reinforcement learning(MARL) formulation for codebook based beamforming control. It takes advantage of the inherienntly distributed structure in a wirelessly powered network and lay the ground work for fully locally computed beam control algorithms.
