Performance Evaluation and Optimization of LPWA IoT Networks: A Stochastic Geometry Approach [PDF]
2018 IEEE Global Communications Conference (GLOBECOM), 2018 Leveraging grant-free radio access for enabling lowpower wide-area (LPWA) Internet of Things (IoT) connectivity has attracted lots of attention in recent years. Regarding lack of research on LPWA IoT networks, this work is devoted to reliability modeling, battery-lifetime analysis, and operation-control of such networks. We derive the interplay amongst

Capturing coefficient increase and energy spread decrease in LPWA
Journal of Physics: Conference Series, 2016 The acceleration of electrons in laser plasma channels is one of the contemporary ideas on energy frontier of accelerators. Many simulations and experimental studies are now provided. But two main laser plasma acceleration problems are not solved until now: low fraction of particles is capturing into acceleration and accelerated electrons have very ...
