A Survey of Energy Modeling and Efficiency Techniques of Sensors for IoT Systems

Sensors power the entire internet of things applications. Sensors are one of the major power consuming devices of IoT networks while transmitting and receiving data. Optimizing power is one of the approaches to solve this problem. This paper surveys various power modeling techniques of sensors that are applicable to the internet of things and sensor networks applications. Various techniques and strategies have been studied in this paper. Some of the techniques that are studied and surveyed are transmission power modeling, power modeling of the sensor for sensor subsystems and IoT systems, clustered approach, energy harvesting models and transmission distance modeling. Our survey proposes that there exists a valid and feasible model for a given application that satisfies the power constraints of the sensor devices.
