物联网（IoT）是一个新兴的概念，旨在将数十亿台设备相互连接起来。物联网设备从周围环境中感知、收集和传输重要信息。这种在数十亿设备之间交换非常大量的信息产生了巨大的能源需求。绿色物联网设想的概念是降低物联网设备的能耗，使环境安全。受实现物联网可持续发展环境的启发，我们首先概述了绿色物联网以及过度使用高能耗物联网设备所面临的挑战。然后，我们讨论和评估可用于最大限度地减少物联网能耗的策略，例如设计节能的数据中心，从传感器传输数据的节能方式，以及设计节能策略。此外，我们批判性地分析了绿色物联网的战略，并提出了五个原则，可以采用，以实现绿色物联网。最后，我们考虑物联网非常重要方面的案例研究，即，智能手机，我们提供了一个简单而简洁的视图，以改进当前的实践，使物联网在2020年及以后的世界更加绿色。
Internet of Things (IoT) is an emerging concept, which aims to connect billions of devices with each other. The IoT devices sense, collect, and transmit important information from their surroundings. This exchange of very large amount of information amongst billions of devices creates a massive energy need. Green IoT envisions the concept of reducing the energy consumption of IoT devices and making the environment safe. Inspired by achieving a sustainable environment for IoT, we first give the overview of green IoT and the challenges that are faced due to excessive usage of energy hungry IoT devices. We then discuss and evaluate the strategies that can be used to minimize the energy consumption in IoT, such as designing energy efficient datacenters, energy efficient transmission of data from sensors, and design of energy efficient policies. Moreover, we critically analyze the green IoT strategies and propose five principles that can be adopted to achieve green IoT. Finally, we consider a case study of very important aspect of IoT, i.e., smart phones and we provide an easy and concise view for improving the current practices to make the IoT greener for the world in 2020 and beyond.
