To resolve energy depletion issues in massive Internet of Things sensor networks, we developed a set of distributed energy beamforming methods with one‐bit feedback and clustering for multi‐node wireless energy transfer, where multiple single‐antenna distributed energy transmitters (Txs) transfer their energy to multiple nodes wirelessly. Unlike previous works focusing on distributed information beamforming using a single energy receiver (Rx) node, we developed a distributed energy beamforming method for multiple Rx nodes. Additionally, we propose two clustering methods in which each Tx node chooses a suitable Rx node. Furthermore, we propose a fast distributed beamforming method based on Tx sub‐clustering. Through computer simulations, we demonstrate that the proposed distributed beamforming method makes it possible to transfer wireless energy to massive numbers of sensors effectively and rapidly with small implementation complexity. We also analyze the energy harvesting outage probability of the proposed beamforming method, which provides insights into the design of wireless energy transfer networks with distributed beamforming.

具有一位反馈和集群的分布式波束成形，用于多节点无线能量传输

为了解决大规模物联网传感器网络中的能量耗竭问题，我们开发了一套具有位反馈和群集的分布式能量波束成形方法，用于多节点无线能量传输，其中多个单天线分布式能量发射器（Tx）传输它们无线地为多个节点供电。与以前的工作侧重于使用单个能量接收器（Rx）节点进行分布式信息波束成形不同，我们开发了针对多个Rx节点的分布式能量波束成形方法。此外，我们提出了两种群集方法，其中每个Tx节点都选择一个合适的Rx节点。此外，我们提出了一种基于Tx子集群的快速分布式波束成形方法。通过计算机模拟，我们证明了所提出的分布式波束成形方法使得可以以较小的实现复杂度有效且快速地将无线能量传输到大量传感器。我们还分析了所提出的波束成形方法的能量收集中断概率，这为深入了解具有分布式波束成形的无线能量传输网络的设计提供了见识。
