Presence Aware Power Saving Mode (PA-PSM) enhancement for IoT devices for energy conservation [thesis]

Abstract

The smart home is gradually captivating worldwide and provides the best services to human life. It wipes traditional houses by turning them into smart homes; nowadays, numerous energy-efficient devices lead to optimal energy exploitation. It enhances the inhabitant's lifestyle, safety, and comfort since it is suitable for all users of diverse incomes and ages. It is essential to exploit the technology to develop energy-efficient smart homes. The design and implementation of energy-efficient smart homes are proposed in this research work. It is a proposed model that controls home appliances, monitors energy usage and sends low priority devices in switch OFF mode to save energy. The system uses a combination of a central controller, sensors, modules and PA-PSM algorithm proposed by this research work. The PIR sensor locates the human within the home, brings the nearby appliance in active mode, and sends the rest in switch OFF mode, the LDR (light dependent resistor) to sense the intensity of the light to decide if the light is needed else stays in switch OFF mode. The Arduino manages all the sensors, modules, home appliances including scheduling, and energy consumption of individual home appliances. The system automates the process and accepts the commands from end-user through mobile applications to use home appliances. It is a novel approach that has several experiments that help to reduce 20.34% of energy consumption. The rapidly growing industry has already reached $92bn and has a growth rate of 16% each year, reaching $192bn by the year 2025; so far, the US is the most significant share of using the smart home application. However, it also has entered the European market, especially in voice-controlled applications. This industry is growing rapidly and currently has 21bn active connections. These smart devices will produce substantial data along with the increment of energy consumption significantly. The significant use of energy puts pressure on the energy producer and leading to energy scarceness. The researchers and IT industries are focusing mainly on this area and expect 1tn of sensor interconnects by 2025; even if these sensors have ten years of battery life, it still requires replacing 275mn batteries every day. Therefore, it is necessary to reduce energy consumption in the smart home. "Presence Aware Power Saving Mode (PA-PSM) Development for IoT devices for energy conservation" is a novel approach proposed with the help of the proposed algorithm to reduce power consumption up to 20.34% in the smart home.
