Title: Energy Harvesting for Machine-to-Machine Communications in LTE-advanced Networks

Speaker: Dr. Sina Khoshabi-Nobar, Postdoctoral Fellow (supervisors: Professors Samy Mahmoud and Mohamed H. Ahmed), Carleton University

Abstract:  In this presentation, a brief introduction to energy
harvesting (EH) communications and machine-to-machine (M2M)
communications is presented and the major challenges in these research
areas are discussed. Then, we analyze the performance of the random
access procedure of the LTE-A network in the EH-M2M scenario, where
the 3GPP’s access class barring mechanism (ACB) is employed to
decrease the number of packet collision. Our analytic and simulation
results suggest that in the EH-M2M scenario, despite the lower number
of contending nodes in comparison with the non-EH scenario, the ACB
parameters must be chosen in a more conservative way to avoid
excessive collisions.

Bio: Sina Khoshabi-Nobar received his B.Sc., M.Sc., and PhD degrees
from University of Tabriz, Iran, in 2011, 2013, and 2017,
respectively. His PhD dissertation was entitled “Green Cognitive Radio
Network with Central Energy Harvester/Transmitter Node”. Currently, he
is a postdoctoral fellow at Carleton University under the supervision
of Prof. S. Mahmoud and Prof. M.H. Ahmed, where he is conducting
research on energy-harvesting-based M2M communications in cellular
networks. His research interests include green communications,
wireless energy transfer, MAC layer performance analysis, and M2M
communications in cellular networks.
