Energy Aware Fog-enabled green IoT networks

Internet of Things (IoT) has reformed the idea how to connect with the devices and recognized for recent advances in numerous applications ranges from healthcare, agriculture, education, industries, automobiles and many more. It has revolutionized the way we connect and interact with devices. With the growth in the number of IoT devices and its applications in smart devices, large amount of data is being generated by these devices resulted in various challenges in the basic model of Cloud Computing. From consumption of high amounts of energy, repeated network failures and diminished storage extent. A new technology Fog Computing, with the motive of extending the cloud computing features near the edge of the network has been introduced, which enhances the efficiency of IoT devices. With benefits of fog computing ranging from reducing latency to improvement in mobility. It provides faster response time with minimum energy usage, making it favourable choice over the cloud. This paper compares and presents different models proposed and energy aware techniques to minimize energy usage in IoT networks. The study also identifies the different challenges for energy conservation.
