Fair scheduling algorithms have been proposed to tackle the problem of bursty and location-dependent errors in wireless packet networks. Most of those algorithms ensure the fairness property and guarantee the QoS of all sessions in a large-scale cellular network such as GSM or GPRS. In this paper, we propose the Weighted-Sacrificing Fair Queueing (WSFQ) scheduling algorithm for small-area and d...

The advantages of using stochastic process algebra to specify performance models are well-documented. There remains, however, a reluctance in some quarters to use process algebras; this is particularly the case amongst queueing theorists. This paper demonstrates the use of a Markovian process algebra to represent a wide range of queueing models. Moreover, it shows that the most common interacti...

System analysis is often needed with respect to both qualitative and quantitative aspects. In the last decades, several formalisms have been developed that attempt to combine these aspects in one description. Present emphasis is on Stochastic Petri Nets. Amongst others, one disadvantage of these formalisms lies with the diiculties when describing scheduling strategies with Petri Net elements. T...

The authors study the queueing process in a single-server queueing system with state dependent service and with the input modulated by a semi-Markov process embedded in the queueing process. It is also assumed that the server capacity is r > 1 and that any service act will not begin until the queue accumulates at least r units. In this model, therefore, idle periods also depend upon the queue l...

The rapid penetration of electric vehicles may lead to peak problems in a traditional grid so that some of the smart grid research is focused on charging strategies for electric vehicles. The charging problem is suitable for using a queue structure, and fuzzy queueing can be implemented for this purpose. This paper presents a fuzzy queueing based model, which can also control the power demand o...

Queueing network modeling of manufacturing systems has been addressed by a large number of researchers. The purpose of this paper is to provide a bibliography of material concerned with modeling of production and transfer lines using queueing networks. Both production and transfer lines have a product-flow layout and are used in mass manufacturing. We denote production lines as flow lines with ...

Distributed fair queueing in shared-medium ad hoc wireless networks is non-trivial because of the unique design challenges in such networks, such as location-dependent contention, distributed nature of ad hoc fair queueing, channel spatial reuse, and scalability in the presence of node mobility. In this paper, we seek to devise new distributed, localized, scalable and efficient solutions to thi...

Abstract We investigate the 36-year history of research published in journal Queueing Systems: Theory and Applications (QUESTA), to uncover trends over time topics themes covered as well authorship, co-authorship, institutional affiliation. Our analysis includes three different approaches. First, we conduct a content titles abstracts using selected keywords examine models , methods concepts app...

Objective: In this study we consider a two-state retrial queueing system with feedback having two identical parallel servers. Transient state probabilities for exact number of arrivals and departures from the will be obtained when both, one or none servers is busy. Numerical graphical solutions also obtained. Methods: The difference-differential equations governing are solved recursively, Lapla...

This paper presents a VESI implementation of a resource allocation scheme, based on the concept of weighted fair queueing. The design can be used in Asynchronous Transfer Mode (ATM) networks to ensure fairness and robustness. Weighted fair queueing is a scheduling and buffer management scheme that can provide a resource allocation policy and enforcement of this policy. It can be used in network...
