Multi-Server Secure Aggregation with Unreliable Communication Links
GLOBECOM 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.

Analysis and Comparison of Queue with N-Policy and Unreliable Server
Discrete Dynamics in Nature and Society, 2020 This work considers a queueing system with N-policy and unreliable server, where potential customers arrive at the system according to Poisson process. If there is no customer waiting in the system, instead of shutting down, the server turns into dormant

Cost-Benefit Analysis of a Standby Retrial System with an Unreliable Server and Switching Failure
Computation, 2022 In many industries and plants, a stable power supply system with acceptable cost/benefit is essential. This paper investigates the cost-effectiveness of an unreliable retrial system that includes standby generators and experiences the switchover failures

Study of feedback queueing system with unreliable waiting server under Multiple Differentiated Vacation Policy [PDF]
Ratio Mathematica, 2021 This manuscript analyses a queueing system with Bernoulli schedule feedback of customers, unreliable waiting server under differentiated vacations. The unsatisfied customer may again join the queue with probability α, following Bernoulli schedule.

Informatika, 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.

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

Computation, 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.

Analysis of bulk service queuing system with rework, unreliable server, resuming service and two kinds of multiple vacation [PDF]
Yugoslav Journal of Operations Research, 2023 In this paper, we discuss a batch arrival bulk service queue with rework for the faculty item, possibility of breakdown, repair, and two kinds of multiple vacation with different threshold policy.

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