Wireless Sensor Network has become part of everyday life. Due to very small size of sensor nodes and their limited battery power a lot of work has been done in the area of energy management. Many routing protocols have been developed for using battery power efficiently but these protocols sacrifice QoS for this energy efficiency. Energy Harvesting technologies have been proposed to improve the ...

There has been a significant increase in the research on vibration-based energy harvesting in recent years. Most research is focused on a particular technology, and it is often difficult to compare widely differing designs and approaches to vibration-based energy harvesting. The aim of this study is to provide a general theory that can be used to compare different approaches and designs for vib...

What is a WSN or Low Power Lossy Network (LLN)? § Sensor node – a highly constrained small device § sensor that can measure physical data (e.g., temperature, humidity, light, vibration, CO2) § actuator capable of performing a task (e.g., switch on, change traffic lights, rotate a mirror) § radio device to receive commands, send measured data or control information § energy supply – battery...

Devices in future Internet of Things (IoT) will be scavenging energy from the ambiance for all their operations. They face challenges in various aspects of network organization and operation due to the nature of ambient energy sources such as, solar insolation, vibration and motion. In this paper we analyze the classical two-way algorithm for neighbor discovery (ND) in an energy harvesting IoT....

Energy harvesting has been proved to be a novel solution to replace the batteries in remote power supply applications. Unfortunately, the limited capacity and low efficiency of output power constraint the practical applications of energy harvesting in daily life. After a systematic review of previous researches about energy harvesting in power management perspective, a circuit design, which foc...

The concept is to capture the normally lost energy surrounding a system and converting it into electrical energy that can be used to extend the lifetime of that system’s power supply or possibly provide an endless supply of energy to an electronic device which has led to power harvesting. One of the most interesting methods of obtaining the energy surrounding a system is to use piezoelectric ma...
