Cooperative Transmission and Probabilistic Caching for Clustered D2D Networks
Ramy Amer, Hesham ElSawy, Jacek Kibiłda +2
In this paper, we aim at maximizing the cache offloading gain for a clustered \ac{D2D} caching network by exploiting probabilistic caching and cooperative transmission among the cl…
Caching to the Sky: Performance Analysis of Cache-Assisted CoMP for Cellular-Connected UAVs
Ramy Amer, Walid Saad, Hesham ElSawy +2
Providing connectivity to aerial users, such as cellular-connected unmanned aerial vehicles (UAVs) or flying taxis, is a key challenge for tomorrow's cellular systems. In this pape…
Meta Distribution of Downlink Non-Orthogonal Multiple Access (NOMA) in Poisson Networks
Konpal Shaukat Ali, Hesham ElSawy, Mohamed-Slim Alouini
We study the meta distribution (MD) of the coverage probability (CP) in downlink non-orthogonal-multiple-access (NOMA) networks. Two schemes are assessed based on the location of t…
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…
Integrating UAVs into Existing Wireless Networks: A Stochastic Geometry Approach
Rabe Arshad, Lutz Lampe, Hesham ElSawy +1
The integration of unmanned aerial vehicles (UAVs) into wireless networks has opened a new horizon to meet the capacity and coverage requirements foreseen in future wireless networ…
Aeronautical Data Aggregation and Field Estimation in IoT Networks: Hovering & Traveling Time Dilemma of UAVs
Osama M. Bushnaq, Abdulkadir Celik, Hesham ElSawy +2
The next era of information revolution will rely on aggregating big data from massive numbers of devices that are widely scattered in our environment. Most of these devices are exp…
Optimizing Joint Probabilistic Caching and Communication for Clustered D2D Networks
Ramy Amer, Hesham Elsawy, M. Majid Butt +3
Caching at mobile devices and leveraging device-to-device (D2D) communication are two promising approaches to support massive content delivery over wireless networks. The analysis…
On Minimizing Energy Consumption for D2D Clustered Caching Networks
Ramy Amer, M. Majid Butt, Hesham ElSawy +3
We formulate and solve the energy minimization problem for a clustered device-to-device (D2D) network with cache-enabled mobile devices. Devices are distributed according to a Pois…
Handover Rate Characterization in 3D Ultra-Dense Heterogeneous Networks
Rabe Arshad, Hesham ElSawy, Lutz Lampe +1
Ultra-dense networks (UDNs) envision the massive deployment of heterogenous base stations (BSs) to meet the desired traffic demands. Furthermore, UDNs are expected to support the d…
Downlink Non-Orthogonal Multiple Access (NOMA) in Poisson Networks
Konpal Shaukat Ali, Martin Haenggi, Hesham ElSawy +2
A network model is considered where Poisson distributed base stations transmit to power-domain non-orthogonal multiple access (NOMA) users (UEs) each {that employ successive in…
