| Περίληψη: | In this dissertation we investigate problems which arise from the application of wireless energy transfer in ad hoc and sensor networks and we address those problems by designing efficient protocols. The dissertation is comprised of 10 Chapters. Chapters 1 and 2 provide an introduction to the subject and to the relevant state of the art. In Chapters 3-9 the reader can find the scientific core of the dissertation. Insights for future work are provided in Chapter 10. Finally, there are also two Appendices, one with a list of scientific publications which were produced during the writing of this work and another with an extended abstract of the dissertation in Greek language.
The scientific core of the dissertation is divided in two parts. Chapters 3-6 focus on mobile wireless charging in stationary sensor networks, while Chapters 7-9 investigate different models and alternative applications of wireless energy transfer in ad hoc networks. More specifically, at the first part, in Chapter 3, we focus on wireless charging with a single Mobile Charger assuming uniform network deployments and in Chapter 4 on non-uniform network deployments. Wireless charging with multiple Mobile Chargers is presented in Chapter 5 and further investigated in Chapter 6 by introducing hierarchical collaboration. The different models, which are introduced in the second part of the dissertation, consist of interactive wireless charging in populations of mobile peers in Chapter 7, radiation aware wireless charging in Chapter 8 and a realistic model which takes into account fundamental properties of superposition of electromagnetic fields in Chapter 9.
