摘要:

物联网(IoT)包括越来越多的低功耗和低成本设备,这些设备可以自主地与周围环境进行交互。由于物联网的普及,未来的物联网部署将是大规模的,这就需要节能系统来延长其使用寿命并改善用户体验。射频无线能量传输具有为大规模物联网网络供电的潜力,从而无需使用所谓的功率信标(PB)来频繁更换电池。在本文中,我们提供了一个框架,使用设备的位置信息和当前的电池状态,以最大限度地减少PB的总发射功率。我们的策略旨在减少PBs的耗电量及减轻电磁辐射对人体健康的可能影响。我们还提出了非常遥远的集群的情况下,分析的见解,并评估其适用性。数值结果表明,我们提出的框架降低了中断概率的PB的数量和/或能源需求的增加。

英文摘要:

The Internet of Things (IoT) comprises an increasing number of low-power and low-cost devices that autonomously interact with the surrounding environment. As a consequence of their popularity, future IoT deployments will be massive, which demands energy-efficient systems to extend their lifetime and improve the user experience. Radio frequency wireless energy transfer has the potential of powering massive IoT networks, thus eliminating the need for frequent battery replacement by using the so-called power beacons (PBs). In this paper, we provide a framework for minimizing the sum transmit power of the PBs using devices' positions information and their current battery state. Our strategy aims to reduce the PBs' power consumption and to mitigate the possible impact of the electromagnetic radiation on human health. We also present analytical insights for the case of very distant clusters and evaluate their applicability. Numerical results show that our proposed framework reduces the outage probability as the number of PBs and/or the energy demands increase.
