Device-to-Device Coded Caching with Distinct Cache Sizes
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
This paper considers a cache-aided device-to-device (D2D) system where the users are equipped with cache memories of different size. During low traffic hours, a server places conte…
Benefits of Coded Placement for Networks with Heterogeneous Cache Sizes
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
In this work, we study coded placement in caching systems where the users have unequal cache sizes and demonstrate its performance advantage. In particular, we propose a caching sc…
Coded Caching for Heterogeneous Systems: An Optimization Perspective
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
In cache-aided networks, the server populates the cache memories at the users during low-traffic periods, in order to reduce the delivery load during peak-traffic hours. In turn, t…
On Coded Caching with Heterogeneous Distortion Requirements
Abdelrahman M. Ibrahim, Ahmed A. Zewail, Aylin Yener
This paper considers heterogeneous coded caching where the users have unequal distortion requirements. The server is connected to the users via an error-free multicast link and des…
Stability Analysis of Slotted Aloha with Opportunistic RF Energy Harvesting
Abdelrahman M. Ibrahim, Ozgur Ercetin, Tamer ElBatt
Energy harvesting (EH) is a promising technology for realizing energy efficient wireless networks. In this paper, we utilize the ambient RF energy, particularly interference from n…
Coverage Probability Analysis for Wireless Networks Using Repulsive Point Processes
Abdelrahman M. Ibrahim, Tamer ElBatt, Amr El-Keyi
The recent witnessed evolution of cellular networks from a carefully planned deployment to more irregular, heterogeneous deployments of Macro, Pico and Femto-BSs motivates new anal…
