Abstract
 
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 like designing energy efficient datacenters, energy efficient transmission of data from sensors and design of energy efficient policies etc. Moreover, we critically analyze the green IoT strategies and propose 5 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.

Singapore to establish Additive Manufacturing Facility and Applications in Maritime Sector

The facility’s location also leverages PSA’s parts supplier base and facility operations to support just-in-time inventory. This move towards digitised inventories reduces the need to hold excess inventory, which lowers storage costs, while shortening turnaround time from weeks to days due to improved availability of spare parts. In the long run, PSA will expand the scope of these services to the wider maritime industry, including ship owners, to help build its business adjacencies.
