Multi-Server Secure Aggregation with Unreliable Communication Links

open access: yesGLOBECOM 2023 - 2023 IEEE Global Communications Conference, 2023
In many distributed learning setups such as federated learning (FL), client nodes at the edge use individually collected data to compute local gradients and send them to a central master server. The master server then aggregates the received gradients and broadcasts the aggregation to all clients, with which the clients can update the global model.

STATIONARY CHARACTERISTICS OF UNRELIABLE QUEUEING SYSTEM WITH BATCH MARKOVIAN ARRIVAL PROCESS AND RESERVE SERVER

open access: yesInformatika, 2016
In the paper, a queueing system with unreliable server and so called «cold» redundancy is analyzed. The system consists of an infinite buffer, the main unreliable server and the reliable reserve server.

ANASE: Lessons from 'Unreliable Findings' [PDF]

open access: yes, 2008
In late 2007, the ANASE (Attitudes to Noise from Aviation Sources in England) report was published. It claimed that people are increasingly annoyed by aircraft noise, and it estimated how much they would be willing to pay to get rid of it.

Analysis of an unreliable server with soft failures and working vacations and its application in a smart healthcare system

open access: yesResults in Control and Optimization, 2023
The majority of the studies on queues with failing servers focused on catastrophic failures. Catastrophic failures are actually a particular kind of server failure that causes system clearing.

Asymptotic Diffusion Analysis of Retrial Queueing System M/M/1 with Impatient Customers, Collisions and Unreliable Servers

open access: yesAxioms, 2022
In this paper, a retrial queueing system of the M/M/1 type with Poisson flows of arrivals, impatient customers, collisions, and an unreliable service device is considered.

Reputation-Aware Multi-Agent DRL for Secure Hierarchical Federated Learning in IoT

open access: yesIEEE Open Journal of the Communications Society, 2023
Aiming at protecting device data privacy, Federated Learning (FL) is a framework of distributed machine learning in which devices’ local model parameters are exchanged with a centralized server without revealing the actual data.

Preemptive Priority Markovian Queue Subject to Server Breakdown with Imperfect Coverage and Working Vacation Interruption

open access: yesComputation, 2023
This work considers a preemptive priority queueing system with vacation, where the single server may break down with imperfect coverage. Various combinations of server vacation priority queueing models have been studied by many scholars.

Two-way communication retrial queue with unreliable server and multiple types of outgoing calls

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2020
Retrial queue under consideration is the model of call center operator switching between input and outgoing calls. Incoming calls form a Poisson point process.
