Application of IoT in Green Computing

The Internet of things (IoT) enables global connectivity over the worldwide physical objects. The world is made smart with the development of science and technology, by people collaborating automatically with heterogeneous devices. The exchange of massive information between the devices gives rise to enormous energy requirements. The IoT is interconnected to big data analytics and cloud computing to predict the behavior of smart devices, provide useful business insights, and act as a feedback control. In addition, most of the organizations would adapt to the growing interest of smart world which in turn energy demand increases more rapidly. Moreover, there is a never-ending increase in number of vendors and users of various technologies. Green IoT prominently focuses on reducing the environmental problems and creating a sustainable environment related to IoT. It has been emphasized that the utilization of energy-efficient technologies in IoT either reduces the impact of greenhouse gases or inhibit greenhouse effect in various IoT applications. Green IoT assists in maintaining the climatic condition by introducing low energy consumption devices or electrical appliances, minimizing greenhouse gas emissions, utilizing carbon-free materials, and promoting reusability. In order to achieve sustainable environment, an outline of Green IoT and its applications are described in the perspective of minimizing the energy utilization in IoT. The designing of green data centers, sensor network, and cloud computing is discussed with certain policies in order to save energy. In addition, the different Green IoT strategies are analyzed and the principles that can be adapted to attain Green IoT also discussed. Finally, various applications of IoT are described such as smart home which allows the user to control the smart devices like automated doors, smart locks, security cameras, electrical appliances with the application on a smart phone or any other connected devices. Smart e-health is useful in monitoring and tracking patients, and smart city assists people by interconnecting systems, thereby offers required services in order to provide a smarter view for the present scenario and which in turn makes the IoT greener.
