Zusammenfassung: | Internet of things (IoT) is a revolutionizing technology which aims to create
an ecosystem of connected objects and embedded devices and provide ubiquitous
connectivity between trillions of not only smart devices but also simple
sensors and actuators. Although recent advancements in miniaturization of
devices with higher computational capabilities and ultra-low power
communication technologies have enabled the vast deployment of sensors and
actuators everywhere, such an evolution calls for fundamental changes in
hardware design, software, network architecture, data analytic, data storage
and power sources. A large portion of IoT devices cannot be powered by
batteries only anymore, as they will be installed in hard to reach areas and
regular battery replacement and maintenance are infeasible. A viable solution
is to scavenge and harvest energy from environment and then provide enough
energy to the devices to perform their operations. This will significantly
increase the device life time and eliminate the need for the battery as an
energy source. This survey aims at providing a comprehensive study on energy
harvesting techniques as alternative and promising solutions to power IoT
devices. We present the main design challenges of IoT devices in terms of
energy and power and provide design considerations for a successful
implementations of self-powered IoT devices. We then specifically focus on
piezoelectric energy harvesting and RF energy harvesting as most promising
solutions to power IoT devices and present the main challenges and research
directions. We also shed light on the security challenges of energy harvesting
enabled IoT systems and green big data. |
