物联网（IoT）是实现智慧城市概念的有效观察和管理的完美候选者。这需要部署大量的无线设备。然而，为数千甚至数百万台设备补充电池可能很难甚至不可能。为了解决这个问题，能源收集物联网（IoEHT）被提出。虽然最初的IoEHT研究集中在能量收集（EH）作为一种辅助电源供应方法，但现在设想完全无电池和自给自足的系统。利用智慧城市概念提供的各种资源，有助于我们充分了解EH的能力。通过这种方式，我们解决了IoEHT的主要缺点;混合EH物联网（IoHEHT）的可用性，不可靠性和不足。在本文中，我们调查了各种EH机会，提出了一种混合EH系统，并讨论了无电池运行的能源和数据管理问题。我们在数学上证明了混合EH的优势相比，单一来源的收获以及。我们还指出了硬件要求，并提出了针对智能城市概念的IoHEHT的不同网络层的开放研究方向。
Internet of Things (IoT) is a perfect candidate to realize efficient observation and management for Smart City concept. This requires deployment of large number of wireless devices. However, replenishing batteries of thousands, maybe millions of devices may be hard or even impossible. In order to solve this problem, Internet of Energy Harvesting Things (IoEHT) is proposed. Although the first studies on IoEHT focused on energy harvesting (EH) as an auxiliary power provisioning method, now completely battery-free and self-sufficient systems are envisioned. Taking advantage of diverse sources that the concept of Smart City offers helps us to fully appreciate the capacity of EH. In this way, we address the primary shortcomings of IoEHT; availability, unreliability, and insufficiency by the Internet of Hybrid EH Things (IoHEHT). In this paper, we survey the various EH opportunities, propose an hybrid EH system, and discuss energy and data management issues for battery-free operation. We mathematically prove advantages of hybrid EH compared to single source harvesting as well. We also point out to hardware requirements and present the open research directions for different network layers specific to IoHEHT for Smart City concept.
