A Survey on Energy Efficient, Harvesting & Optimization Approaches in IoT system

The Internet of Things (IoT) is a ubiquitous modern technology that consists of multiple key components such as sensors, cloud storage, humans, and so on. Sensors, intelligent computing devices, self-powered devices and data storage units form the foundation of an IoT network’s system architecture. The Internet of Things (IoT) aims to combine as much of our world as possible. In current era, everybody and everywhere started to use & deploy the internet enabled services. Such embedded systems, Multimedia Pod casts, Smart Microwave ovens, home appliances, Global positioning systems & Health Monitoring devices called as biochips etc., In order to eventually automate all sectors, IoT provides sophisticated communication (through the internet) between a list of services, systems, or services. The IoT links all conceivable items to interact with one another in order to provide people with a safe environment & comfortable living. According to recent studies, we wm have over 35 billion IoT devices by 2030. However, these vast fields present issues such as a paucity of IP addresses, as well as the development of suitable and functional protocols and environments. The several places where IoT can be deployed like Building and Home Automation, Industrial Applications, Infrastructure Management, Environmental Monitoring, Large Scale Deployments, Medical and Healthcare Systems, Transport Systems, Energy Management. In this arena, energy conservation or consumption is critical for real-time applications that must operate for longer periods of time. This review article examines and surveys the important energy efficiency, energy harvesting, and other tactics that are used in the IoT to achieve optimal energy use. Also, based on its technological classification, the major aims of this survey article are to propose distinctive approaches, particularly for energy saving. Each section category will be covered in its own parametric.
