Abstract:
Internet of Things (IoT) provides a link between cyber and physical world by connecting devices over the Internet. Recent advances in hardware, signal processing and communications have made it possible to manufacture low cost and low complexity wireless connected things; which are the key to full scale adoption of the IoT paradigm. On the other hand, with the progress in nanotechnology, things are also quickly moving into to nanoscales, ultimately towards Internet of Bio-Nano Things (IoBNT). Full realization of IoT and IoBNT, however, will depend on resolution of additional challenges. One imminent difficulty is spectrum scarcity, driven by inefficient fixed spectrum assignment approach. Furthermore, majority of the communicating things are traditionally batter-powered, running out of power at fairly random instants after their deployment, which makes battery replenishments infeasible. IoBNT, on the other hand, depends on nanomachines with scarce processing, memory, and networking capabilities. To that end, in this thesis, we focus on energy and spectrum-efficient communication techniques for next-generation networks that are likely to constitute the backbones of IoT and IoBNT. We reveal solutions provided to demanding IoT and IoBNT applications by next-generation networks, including but not limited to spectrum-aware communications, energy-harvesting schemes, utilization of low THz band and modulation schemes for IoBNT applications.
