A Reinforcement Learning Approach for Scheduling in mmWave Networks
Mine Gokce Dogan, Yahya H. Ezzeldin, Christina Fragouli +1
We consider a source that wishes to communicate with a destination at a desired rate, over a mmWave network where links are subject to blockage and nodes to failure (e.g., in a hos…
On optimal relay placement in directional networks
Mine Gokce Dogan, Yahya H. Ezzeldin, Christina Fragouli
In this paper, we study the problem of optimal topology design in wireless networks equipped with highly-directional transmission antennas. We use the 1-2-1 network model to charac…
Gaussian 1-2-1 Networks with Imperfect Beamforming
Yahya H. Ezzeldin, Martina Cardone, Christina Fragouli +1
In this work, we study bounds on the capacity of full-duplex Gaussian 1-2-1 networks with imperfect beamforming. In particular, different from the ideal 1-2-1 network model introdu…
On Distributed Quantization for Classification
Osama A. Hanna, Yahya H. Ezzeldin, Tara Sadjadpour +2
We consider the problem of distributed feature quantization, where the goal is to enable a pretrained classifier at a central node to carry out its classification on features that…
Polynomial-time Capacity Calculation and Scheduling for Half-Duplex 1-2-1 Networks
Yahya H. Ezzeldin, Martina Cardone, Christina Fragouli +1
This paper studies the 1-2-1 half-duplex network model, where two half-duplex nodes can communicate only if they point `beams' at each other; otherwise, no signal can be exchanged…
Secure Communication over 1-2-1 Networks
Gaurav Kumar Agarwal, Yahya H. Ezzeldin, Martina Cardone +1
This paper starts by assuming a 1-2-1 network, the abstracted noiseless model of mmWave networks that was shown to closely approximate the Gaussian capacity in [1], and studies sec…
Gaussian 1-2-1 Networks: Capacity Results for mmWave Communications
Yahya H. Ezzeldin, Martina Cardone, Christina Fragouli +1
This paper proposes a new model for wireless relay networks referred to as "1-2-1 network", where two nodes can communicate only if they point "beams" at each other, while if they…
Wireless Network Simplification: The Performance of Routing
Yahya H. Ezzeldin, Ayan Sengupta, Christina Fragouli
Consider a wireless Gaussian network where a source wishes to communicate with a destination with the help of N full-duplex relay nodes. Most practical systems today route informat…
Half-Duplex Routing is NP-hard
Yahya H. Ezzeldin, Martina Cardone, Christina Fragouli +1
Routing is a widespread approach to transfer information from a source node to a destination node in many deployed wireless ad-hoc networks. Today's implemented routing algorithms…
Communication vs Distributed Computation: an alternative trade-off curve
Yahya H. Ezzeldin, Mohammed Karmoose, Christina Fragouli
In this paper, we revisit the communication vs. distributed computing trade-off, studied within the framework of MapReduce in [1]. An implicit assumption in the aforementioned work…
Efficiently Finding Simple Schedules in Gaussian Half-Duplex Relay Line Networks
Yahya H. Ezzeldin, Martina Cardone, Christina Fragouli +1
The problem of operating a Gaussian Half-Duplex (HD) relay network optimally is challenging due to the exponential number of listen/transmit network states that need to be consider…
Consistency in the face of change: an adaptive approach to physical layer cooperation
Ayan Sengupta, Yahya H. Ezzeldin, Siddhartha Brahma +2
Most existing works on physical-layer (PHY) cooperation (beyond routing) focus on how to best use a given, static relay network--while wireless networks are anything but static. In…
Network Simplification in Half-Duplex: Building on Submodularity
Martina Cardone, Yahya H. Ezzeldin, Christina Fragouli +1
This paper explores the {\it network simplification} problem in the context of Gaussian Half-Duplex (HD) diamond networks. Specifically, given an -relay diamond network, this pr…
