Timely Multi-Process Estimation Over Erasure Channels With and Without Feedback: Signal-Independent Policies
Karim Banawan, Ahmed Arafa, Karim G. Seddik
We consider a multi-process remote estimation system observing independent Ornstein-Uhlenbeck processes. In this system, a shared sensor samples the processes in such a way…
Private Status Updating with Erasures: A Case for Retransmission Without Resampling
Ahmed Arafa, Karim Banawan
A status updating system is considered in which a source updates a destination over an erasure channel. The utility of the updates is measured through a function of their age-of-in…
Delay Sensitive Hierarchical Federated Learning with Stochastic Local Updates
Abdulmoneam Ali, Ahmed Arafa
The impact of local averaging on the performance of federated learning (FL) systems is studied in the presence of communication delay between the clients and the parameter server.…
Timely Multi-Process Estimation with Erasures
Karim Banawan, Ahmed Arafa, Karim G. Seddik
We consider a multi-process remote estimation system observing independent Ornstein-Uhlenbeck processes. In this system, a shared sensor samples the processes in such a way…
Timely Updating with Intermittent Energy and Data for Multiple Sources over Erasure Channels
Christopher Daniel, Ahmed Arafa
A status updating system is considered in which multiple data sources generate packets to be delivered to a destination through a shared energy harvesting sensor. Only one source's…
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…
