4.1. Introduction

The Internet of Things (IoT) represents a new communication trend in the world of IT and telecoms. This new paradigm makes it possible to improve human quality of life while ensuring advanced and intelligent services by means of interconnection between different objects (telephones, sensors, etc.) and entities (humans, animals, etc.) used in our daily life. This new evolution in the communication of information creates different challenges, to which responses are expected to improve users’ Quality of Experience (QoE). One of the major challenges of the IoT is energy consumption, given that connected objects within this type of environment may have limitations in terms of energy capacity. These limitations stem from the fact that the objects are supplied via batteries and it becomes difficult, indeed impossible, to change them manually given the large number of objects that operate in this type of environment. Consequently, it is necessary to minimize the energy consumption of connected objects, making it possible to extend the lifespan of IoT systems. In this chapter, we present in section 4.2 the general concepts relating to energy optimization by defining key terms and the different techniques used. Then, we detail in section 4.3 the characteristics of energy optimization in the IoT, as well as the challenges ...
