Queueing Networks for Vertical Handover [PDF]

open access: yes, 2009
PhDIt is widely expected that next-generation wireless communication systems will be heterogeneous, integrating a wide variety of wireless access networks. Of particular interest recently is a mix of cellular networks (GSM/GPRS and WCDMA) and wireless

Multiserver queueing networks and the tandem queue model [PDF]

open access: yesInternational Journal of Stochastic Analysis, 1998
Using a tandem queue model we evaluate the local “endogenous” (= internal) queueing delay in single server and multiserver queueing networks. The new concept of the apparent overall upstream queueing delay(as perceived by the downstream network) allows us to analyze the distribution of this local queue by interpolating between the distributions of ...

On some queueing systems with server vacations, extended vacations, breakdowns, delayed repairs and stand-bys [PDF]

open access: yes, 2012
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.This research investigates a batch arrival queueing system with a Bernoulli scheduled vacation and random system breakdowns.

Equilibrium strategies for overtaking free queueing networks under partial information [PDF]

open access: yes, 2023
openIn this thesis, we are interested in finding equilibrium strategies for customers arriving at overtaking free queueing networks, only knowing partial information about the state of the system. The overtaking free condition does not allow customers to

The theory of networks of single server queues and the tandem queue model [PDF]

open access: yesInternational Journal of Stochastic Analysis, 1997
We consider the stochastic behavior of networks of single server queues when successive service times of a given customer are highly correlated. The study is conducted in two particular cases: 1) networks in heavy traffic, and 2) networks in which all successive service times have the same value (for a given customer), in order to avoid the ...

A Tandem Queueing Model for Delay Analysis in Disconnected Ad Hoc Networks [PDF]

open access: yes, 2008
Ad hoc network routing protocols may fail to operate in the absence of an end-to-end connection from source to destination. This deficiency can be resolved by so-called delay-tolerant networking which exploits the mobility of the nodes by letting them operate as relays according to the store-carry-and-forward paradigm.

Modeling DECT-2020 as a Tandem Queueing System and Its Application to the Peak Age of Information Analysis

open access: yesMathematics
The Peak Age of Information (PAoI) quantifies the freshness of updates used in cyber-physical systems (CPSs), realized within the Internet of Things (IoT) paradigm, encompassing devices, networks, and control algorithms.

Inventory-Responsive Donor-Management Policy: A Tandem Queueing Network Model

open access: yesManufacturing & Service Operations Management, 2021
Problem definition: In the blood-donor-management problem, the blood bank incentivizes donors to donate, given blood inventory levels. We propose a model to optimize such incentivization schemes under the context of random demand, blood perishability, observation period between donations, and variability in donor arrivals and dropouts.
