Extending the lifetime of NB-IoT devices through Energy-Harvesting techniques

For the Internet of Things (IoT) applications that send a few bytes of sensor information infrequently, several long-range IoT technologies have been conceived. Narrowband IoT (NB-IoT) is one of them that stands out due to its extended coverage, high penetrability, and high reliability features. Envisaged<br/>long device lifetime and the...

Offline Power Allocation and Spectrum Sensing Strategy in Energy-Harvesting Cognitive Radio Networks

Energy-harvesting cognitive radio network has emerged as a solution to increase energy and spectrum efficiency. In this thesis, we propose short-term offline optimal power allocation algorithms for multi-user energy-harvesting cognitive radio networks considering interference between secondary users. Assuming finite and rechargeable batteries...
