Version Age of Information in Clustered Gossip Networks
Baturalp Buyukates, Melih Bastopcu, Sennur Ulukus
We consider a network consisting of a single source and receiver nodes that are grouped into equal-sized clusters. We use cluster heads in each cluster to facilitate communicat…
Timely Status Updating Over Erasure Channels Using an Energy Harvesting Sensor: Single and Multiple Sources
Ahmed Arafa, Jing Yang, Sennur Ulukus +1
A status updating system is considered in which data from multiple sources are sampled by an energy harvesting sensor and transmitted to a remote destination through an erasure cha…
Group Testing with Non-identical Infection Probabilities
Mustafa Doger, Sennur Ulukus
We consider a zero-error probabilistic group testing problem where individuals are defective independently but not with identical probabilities. We propose a greedy set formation m…
Gossiping with Binary Freshness Metric
Melih Bastopcu, Baturalp Buyukates, Sennur Ulukus
We consider the binary freshness metric for gossip networks that consist of a single source and end-nodes, where the end-nodes are allowed to share their stored versions of the…
Timely Private Information Retrieval
Karim Banawan, Ahmed Arafa, Sennur Ulukus
We introduce the problem of \emph{timely} private information retrieval (PIR) from non-colluding and replicated servers. In this problem, a user desires to retrieve a message o…
Symmetric Private Information Retrieval with User-Side Common Randomness
Zhusheng Wang, Sennur Ulukus
We consider the problem of symmetric private information retrieval (SPIR) with user-side common randomness. In SPIR, a user retrieves a message out of messages from non-col…
Freshness Based Cache Updating in Parallel Relay Networks
Priyanka Kaswan, Melih Bastopcu, Sennur Ulukus
We consider a system consisting of a server, which receives updates for files according to independent Poisson processes. The goal of the server is to deliver the latest versio…
Age of Gossip in Networks with Community Structure
Baturalp Buyukates, Melih Bastopcu, Sennur Ulukus
We consider a network consisting of a single source and receiver nodes that are grouped into equal size communities, i.e., clusters, where each cluster includes nodes a…
Gradient Coding with Dynamic Clustering for Straggler-Tolerant Distributed Learning
Baturalp Buyukates, Emre Ozfatura, Sennur Ulukus +1
Distributed implementations are crucial in speeding up large scale machine learning applications. Distributed gradient descent (GD) is widely employed to parallelize the learning t…
Wireless Power Transfer for Future Networks: Signal Processing, Machine Learning, Computing, and Sensing
Bruno Clerckx, Kaibin Huang, Lav R. Varshney +2
Wireless power transfer (WPT) is an emerging paradigm that will enable using wireless to its full potential in future networks, not only to convey information but also to deliver e…
Group Testing with a Graph Infection Spread Model
Batuhan Arasli, Sennur Ulukus
We propose a novel infection spread model based on a random connection graph which represents connections between individuals. Infection spreads via connections between individ…
