Distributed Flooding-based Storage Algorithms for Large-scale Sensor Networks
Salah A. Aly, Hager S. Darwish, Moustafa Youssef +1
In this paper we propose distributed flooding-based storage algorithms for large-scale wireless sensor networks. Assume a wireless sensor network with nodes that have limited p…
Overlapping Multi-hop Clustering for Wireless Sensor Networks
Moustafa Youssef, Adel Youssef, Mohamed Younis
Clustering is a standard approach for achieving efficient and scalable performance in wireless sensor networks. Traditionally, clustering algorithms aim at generating a number of d…
Randomization for Security in Half-Duplex Two-Way Gaussian Channels
Aly El Gamal, Moustafa Youssef, Hesham El Gamal
This paper develops a new physical layer framework for secure two-way wireless communication in the presence of a passive eavesdropper, i.e., Eve. Our approach achieves perfect inf…
ARQ Secrecy: From Theory to Practice
Yara Omar, Moustafa Youssef, Hesham El Gamal
Inspired by our earlier work on Automatic Repeat reQuest (ARQ) secrecy, we propose a simple, yet efficient, security overlay protocol to existing 802.11 networks. Our work targets…
Opportunistic Secrecy with a Strict Delay Constraint
Karim Khalil, O. Ozan Koyluoglu, Hesham El Gamal +1
We investigate the delay limited secrecy capacity of the flat fading channel under two different assumptions on the available transmitter channel state information (CSI). The first…
On the Delay Limited Secrecy Capacity of Fading Channels
Karim Khalil, Moustafa Youssef, O. Ozan Koyluoglu +1
In this paper, the delay limited secrecy capacity of the flat fading channel is investigated under two different assumptions on the available transmitter channel state information…
