Typically, HA provides a centralized control of electrical appliances, such as air conditioners, lighting and security systems and even the home theater. Home Automation (HA) refers to the mechanization and automatic control of various residential activities.

In fact, built on connections between digital devices and nearly anything that can be monitored or controlled electronically, the IoT holds promise for making homes smarter. With the introduction of the IoT, the research and the implementation of home automation are getting more popular. The nodes of a WSN are sensors arranged within an environment, with the aim to detect certain data that are send to one central node in order to process them. The practical significance of the IoT is made possible through enabling technologies such as Wireless Sensor Networks (WSNs), mainly used for sensing operations. In fact, more and more devices, at any-time, even without receiving a physical input, can access the network and interact with the other connected devices. Thanks to the developments of wireless technologies and to studies about IoT, the “anywhere, any-time by anything” communication is no longer considered a true utopia. They may be influenced and influence the surrounding environment by acting as actuators. They have limited resources in terms of processing capacity, memory, energy supply and routing. They are the real objects characterized by cost, shape, weight, etc. The devices can be identified by the following characteristics: The devices that are part of the network of objects are called “smart objects” or “smart things”, that unlike normal devices are able to interact within the communication system in which they are inserted since they have an active role. When considering a global network of smart objects of all kinds, such as computers, appliances, clothes, sensors, interacting with each other through Internet protocols, the reference scenario is called Internet of Things (IoT). With the increasingly rapid development of various communication technologies, more and more devices are able to access the internet and to interact with it. Simulation results reveal that using the proposed approach the device lifetime is increased by 30% with respect to the use of fixed sleeping time. The proposed FLC determines the sleeping time of field devices according to the battery level and to the ratio of Throughput to Workload (Th/Wl). To this end, this paper proposes a fuzzy logic based mechanism that determine the sleeping time of field devices in a home automation environment based on BLE. However, specific techniques can be used in such a way as to further reduce the energy consumption of BLE.

Bluetooth Low Energy (BLE) has a high potential in becoming an important technology for the IoT in low power, low cost, small devices. There is a main requirement that make a wireless protocol ideal for use in the IoT, that is the energy efficiency. Thanks to the introduction of the Internet of Things (IoT), the research and the implementation of home automation are getting more popular because the IoT holds promise for making homes smarter through wireless technologies.
