A matrix continued fraction approach to multiserver retrial queues [PDF]
, 2013 We consider basic M/M/c/c (c≥1) retrial queues where the number of busy servers and that of customers in the orbit form a level-dependent quasi-birth-and-death (QBD) process with a special structure.

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.

Asymptotics of queue length distributions in priority retrial queues [PDF]
Performance Evaluation, 2018 We calculate asymptotics of the distribution of the number of customers in orbit in a two-class priority retrial $M/G/1$-type queueing model. In this model, priority customers wait in line while non-priority customers join an orbit and retry later. Although the generating function and moments of the number of customers in orbit has been analyzed before,

Spectrum Renting with Two Finite Source Pools in Mobile Cellular Networks
Communications, 2015 Spectrum renting is a technique for improving the efficiency of spectrum usage and alleviating the scarcity of the available spectrum in mobile cellular networks. Since the first proposal of spectrum pooling, several works have been done in this area. In

AlgorithmsThis research analyzes a multi-server retrial queue with two types of calls: working vacation and working breakdown. The incoming call may enter the retrial queue and attempt to seize a server after a random delay if all the servers are unavailable upon ...

Mean value analysis of single server retrial queues
, 2010 Mean value analysis is an elegant tool for determining mean performance measures in queueing models. In this paper we show how mean value analysis can be applied to retrial queues.

Reliability Analysis of a Limited-Capacity Dual-Repair System with Hybrid Vacation Policies [PDF]
International Journal of Mathematical, Engineering and Management SciencesThis study investigates the reliability of a machine dual-repair system (MDRS) with limited capacity and multiple operational vacations (OV). Multiple operational vacation is a mechanism that involves the process of the two types of vacation, one as ...
