Grant-Free Opportunistic Uplink Transmission in Wireless-powered IoT: A Spatio-temporal Model
Mohammad Gharbieh, Hesham ElSawy, Mustafa Emara +2
Ambient radio frequency (RF) energy harvesting is widely promoted as an enabler for wireless-power Internet of Things (IoT) networks. This paper jointly characterizes energy harves…
Self-Organized Scheduling Request for Uplink 5G Networks: A D2D Clustering Approach
Mohammad Gharbieh, Ahmed Bader, Hesham ElSawy +3
In one of the several manifestations, the future cellular networks are required to accommodate a massive number of devices; several orders of magnitude compared to today's networks…
Spatiotemporal Model for Uplink IoT Traffic: Scheduling & Random Access Paradox
Mohammad Gharbieh, Hesham ElSawy, Hong-Chuan Yang +2
The Internet-of-things (IoT) is the paradigm where anything will be connected. There are two main approaches to handle the surge in the uplink (UL) traffic the IoT is expected to g…
Tractable Stochastic Geometry Model for IoT Access in LTE Networks
Mohammad Gharbieh, Hesham ElSawy, Ahmed Bader +1
The Internet of Things (IoT) is large-scale by nature. This is not only manifested by the large number of connected devices, but also by the high volumes of traffic that must be ac…
