Diffusion Limit of Multi-Server Retrial Queue with Setup Time
Mathematics, 2020 In the paper, we consider a multi-server retrial queueing system with setup time which is motivated by applications in power-saving data centers with the ON-OFF policy, where an idle server is immediately turned off and an off server is set up upon ...

Asymptotic Diffusion Method for Retrial Queues with State-Dependent Service Rate
Mathematics, 2023 In this paper, we consider a retrial queue with a state-dependent service rate as a mathematical model of a node of FANET communications. We suppose that the arrival process is Poisson, the delay duration is exponentially distributed, the orbit is ...

A Lightweight, Secure and Reliable Geographic Routing Protocol for Urban VANETs
IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a Lightweight Secure and Reliable Geographic Routing (LSRGR) protocol. The protocol operates in two phases: (i) a greedy forwarding strategy with location verification, which leverages key urban routing parameters to select the most reliable forwarder and employs a recovery mechanism against routing failures, and (ii) reliable route

Discrete-time retrial queue with Bernoulli vacation, preemptive resume and feedback customers
Journal of Industrial Engineering and Management, 2015 Purpose: We consider a discrete-time Geo/G/1 retrial queue where the retrial time follows a general distribution, the server subject to Bernoulli vacation policy and the customer has preemptive resume priority, Bernoulli feedback strategy.

Analysis of a Retrial Queue With Two-Type Breakdowns and Delayed Repairs
IEEE Access, 2020 This article studies an M/G/1 retrial queue with two types of breakdowns. When the server is idle, it is subject to breakdowns according to a Poisson process with rate δ and it cannot be repaired immediately.
