Cache-Aided Private Information Retrieval with Partially Known Uncoded Prefetching: Fundamental Limits
Yi-Peng Wei, Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) from non-colluding and replicated databases, when the user is equipped with a cache that holds an uncoded fractio…
Age Minimization in Energy Harvesting Communications: Energy-Controlled Delays
Ahmed Arafa, Sennur Ulukus
We consider an energy harvesting source that is collecting measurements from a physical phenomenon and sending updates to a destination within a communication session time. Updates…
The Capacity of Private Information Retrieval with Partially Known Private Side Information
Yi-Peng Wei, Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) of a single message out of messages from replicated and non-colluding databases where a cache-enabled user (r…
Energy Harvesting Communications under Explicit and Implicit Temperature Constraints
Abdulrahman Baknina, Omur Ozel, Sennur Ulukus
We consider an energy harvesting communication system where the temperature dynamics is governed by the transmission power policy. Different from the previous work, we consider a d…
Fundamental Limits of Cache-Aided Private Information Retrieval with Unknown and Uncoded Prefetching
Yi-Peng Wei, Karim Banawan, Sennur Ulukus
We consider the problem of private information retrieval (PIR) from non-colluding and replicated databases when the user is equipped with a cache that holds an uncoded fraction…
The Capacity of Private Information Retrieval from Byzantine and Colluding Databases
Karim Banawan, Sennur Ulukus
We consider the problem of single-round private information retrieval (PIR) from replicated databases. We consider the case when databases are outdated (unsynchronized), or…
Energy Harvesting Networks with General Utility Functions: Near Optimal Online Policies
Ahmed Arafa, Abdulrahman Baknina, Sennur Ulukus
We consider online scheduling policies for single-user energy harvesting communication systems, where the goal is to characterize online policies that maximize the long term averag…
Near Optimal Online Distortion Minimization for Energy Harvesting Nodes
Ahmed Arafa, Sennur Ulukus
We consider online scheduling for an energy harvesting communication system where a sensor node collects samples from a Gaussian source and sends them to a destination node over a…
Age-Minimal Transmission in Energy Harvesting Two-hop Networks
Ahmed Arafa, Sennur Ulukus
We consider an energy harvesting two-hop network where a source is communicating to a destination through a relay. During a given communication session time, the source collects me…
Multi-Message Private Information Retrieval: Capacity Results and Near-Optimal Schemes
Karim Banawan, Sennur Ulukus
We consider the problem of multi-message private information retrieval (MPIR) from non-communicating replicated databases. In MPIR, the user is interested in retrieving mes…
