“…There are many energy harvesting technologies and new ones may appear in the near future. The most relevant for smart meters and similar applications might be: Ambient radiation: This is based on exploiting the large amount of radio frequency (RF) energy available in the ambient at different frequencies; an example can be seen in [ 25 ]; Photovoltaic (PV): Transforming light radiation into current; it is virtually inexhaustible and probably the one from which greatest energy can be obtained [ 26 ]; Piezoelectric: Using the piezoelectric effect, which converts mechanical strain or ambient vibration into electrical energy; an example can be seen in [ 27 ]; Magnetic induction: Electrical energy is obtained by moving magnets—or changing magnetic fields, as in [ 28 ]—near or inside a coil; Vibration: Vibration energy harvesting may be fitted into the magnetic energy harvesting field, as it usually relies on varying magnetic fields created due to vibrations to generate energy, as designed in [ 29 ]; Pyroelectric and thermoelectric: These are intended to exploit heat in order to obtain electrical energy, whether relying on temperature gradients or time-variant temperatures, as described in [ 30 ]. …”

In this work, a novel current metering device was presented. This device was intended to bring current metering capabilities to a wide variety of scenarios: Developing countries, rural areas, or any situation with technological constraints. The device was designed to provide a straightforward installation with no intrusion in the electrical panels. This was achieved by applying energy harvesting techniques and wireless communication technology for data transmission. The device was able to exploit the magnetic field inducted around a wire carrying electricity as energy harvesting, thus acquiring the power it needed to work. Since very low power was harvested, an efficient treatment for the incoming power and a minimal power consumption system were essential. Although exploiting the magnetic fields inducted around a wire has been used for years, the combination of this technology for both energy harvesting and current metering in an end-user device was off-center. To work in a wide variety of scenarios, it used Sigfox for communications as this brought wide coverage and out-of-the-box functioning. The theoretical design of the device was validated by verification assessments for the joint performance of the individual parts compounding the device, including metering capabilities and wireless communication test-bench. Finally, the metering device was tested under three distinct real-world scenarios that demonstrated the viability of the system. Results show that, depending on the metering period and the average current value in the mains line, the device could work forever acquiring and sending electricity consumption data. Perpetual working was achieved with an average current of 3.1 A to meter every 15 min, and an average current of 5 A for a 5-min metering period.

“…For example, TV towers [51,76], GSM cellular base stations [77,78,79,80], and WiFi access points [81,82] could be important sources to charge wireless energy users. The problem with ambient RF sources is that the power density could be small that ambient RF energy is more likely to be harvested in urban areas, such as a metropolitan city [51,83].…”

“…For the harvest-use mode, the harvested energy is employed immediately by the energy user. Therefore, the energy users are designed in a battery-free manner, e.g., [77,78,79,80,81,82]. In the harvest-use mode, since there is no energy accumulated, the energy user has to be aware of the energy density and energy harvester designs to improve energy harvesting efficiency.…”

With the growing computing power of mobile devices and increasingly sophisticated applications, mobile computing and wireless communication are nowadays pervasive. However, since mobile devices have limited energy storage and sporadic energy supply, energy management remains a critical issue in mobile networks. To address the problem, a few approaches have been introduced to develop intelligent and optimal energy management for mobile networks. Firstly, wireless energy charging can be employed to replenish batteries of mobile devices. The mobile devices can harvest or receive energy to charge its battery Upon the completion of this thesis, I would like to express the greatest gratitude to my supervisor Prof. Dusit Niyato, for offering me the opportunity to research and pursue my doctorate degree in Nanyang Technological University. Without his guidance and advices, my work on optimizations and mobile energy management topics would not have started. Prof. Dusit Niyato is among the most insightful and vigorous researchers I have ever seen, who always "stays hungry" in learning, creating and contributing to the academic community. From him, I still have too much to learn on becoming a real qualified researcher for now, and for the rest of my career whatever it will be. I would like to thank my co-supervisor Prof. Ping Wang, who has help me a lot in the progress of completing my research during these years as a PhD student. She is a strict and serious researcher, who has pointed out hidden problems and flaws in my research papers for countless times, which I have always failed to discover. I would also like to thank Prof. Dong In Kim from Sungkyunkwan University, Korea, for offering me an opportunity to visit and collaborate to complete a research paper as a part of this thesis. I had a very pleasant stay in Korea. As paraphrased from his words, it is always good to go out to meet different people. I would like to express my very sincere thankfulness to my wife Zhou Yi, who also spent four struggling years as a PhD student in the same university with me. Comparing with our peers and friends at our own age, we have not been living a fantastic and fruitful life for the past years since our marriage. There were even times that we feel frustrated and lost. She never blamed me for the choices I made. The words always come to my mind that charity suffereth long, and is kind. Together we will make it through. We also would like to thank our family for the everlasting support and prompt help whenever we are in need. Besides that, I wish to thank all the current and previous members of our research group for all the collaborations and discussions both in research and daily life. I would like to thank all the staffs and students of Parallel and Distributed Computing Centre (PDCC), the place where this thesis has been done, and most time of my four years has been spent.
