Private Set Intersection: A Multi-Message Symmetric Private Information Retrieval Perspective
Zhusheng Wang, Karim Banawan, Sennur Ulukus
We study the problem of private set intersection (PSI). In this problem, there are two entities , for , each storing a set , whose elements are picked f…
Age of Information for Updates with Distortion: Constant and Age-Dependent Distortion Constraints
Melih Bastopcu, Sennur Ulukus
We consider an information update system where an information receiver requests updates from an information provider in order to minimize its age of information. The updates are ge…
Timely Distributed Computation with Stragglers
Baturalp Buyukates, Sennur Ulukus
We consider a status update system in which the update packets need to be processed to extract the embedded useful information. The source node sends the acquired information to a…
Improved Storage for Efficient Private Information Retrieval
Karim Banawan, Batuhan Arasli, Sennur Ulukus
We consider the problem of private information retrieval from \emph{storage-constrained} databases. In this problem, a user wishes to retrieve a single message out of messa…
Age of Information in G/G/1/1 Systems: Age Expressions, Bounds, Special Cases, and Optimization
Alkan Soysal, Sennur Ulukus
We consider the age of information in G/G/1/1 systems under two service discipline models. In the first model, if a new update arrives when the service is busy, it is blocked; in t…
Age of Information Scaling in Large Networks with Hierarchical Cooperation
Baturalp Buyukates, Alkan Soysal, Sennur Ulukus
Given randomly located source-destination (S-D) pairs on a fixed area network that want to communicate with each other, we study the age of information with a particular focus…
Age of Information in Multicast Networks with Multiple Update Streams
Baturalp Buyukates, Alkan Soysal, Sennur Ulukus
We consider the age of information in a multicast network where there is a single source node that sends time-sensitive updates to receiver nodes. Each status update is one of…
Age of Information for Updates with Distortion
Melih Bastopcu, Sennur Ulukus
We consider an information update system where an information receiver requests updates from an information provider in order to minimize its age of information. The updates are ge…
Gradient Coding with Clustering and Multi-message Communication
Emre Ozfatura, Deniz Gunduz, Sennur Ulukus
Gradient descent (GD) methods are commonly employed in machine learning problems to optimize the parameters of the model in an iterative fashion. For problems with massive datasets…
The Capacity of Private Information Retrieval from Heterogeneous Uncoded Caching Databases
Karim Banawan, Batuhan Arasli, Yi-Peng Wei +1
We consider private information retrieval (PIR) of a single file out of files from non-colluding databases with heterogeneous storage constraints $\mathbf{m}=(m_1, \cdots,…
Interference Regime Enforcing Rate Maximization for Non-Orthogonal Multiple Access (NOMA)
Tugba Erpek, Sennur Ulukus, Yalin E. Sagduyu
An interference regime enforcing rate maximization scheme is proposed to maximize the achievable ergodic sum-rate of the parallel Gaussian interference channels by enforcing very s…
Using Erasure Feedback for Online Timely Updating with an Energy Harvesting Sensor
Ahmed Arafa, Jing Yang, Sennur Ulukus +1
A real-time status updating system is considered, in which an energy harvesting sensor is acquiring measurements regarding some physical phenomenon and sending them to a destinatio…
