Load balancing in parallel infinite-server queues with action delay via phase representation
Kazuma Abe, Tuan Phung-Duc
Spatially distributed service systems rely on state-dependent routing to allocate users, tasks, or requests to less-loaded service nodes. In practice, a routing decision does not t…
Modified Erlang loss system for cognitive wireless networks
E. V. Morozov, S. S. Rogozin, H. Q. Nguyen +1
This paper considers a modified Erlang loss system for cognitive wireless networks and related applications. A primary user has preemptive priority over secondary users and the pri…
Retrial Queueing Models: A Survey on Theory and Applications
Tuan Phung-Duc
Retrial phenomenon naturally arises in various systems such as call centers, cellular networks and random access protocols in local area networks. This paper gives a comprehensive…
Asymptotics of Queue Length Distributions in Priority Retrial Queues
Joris Walraevens, Dieter Claeys, Tuan Phung-Duc
We calculate asymptotics of the distribution of the number of customers in orbit in a two-class priority retrial -type queueing model. In this model, priority customers wait…
The stability condition of BMAP/M/ queues
Moeko Yajima, Tuan Phung-Duc, Hiroyuki Masuyama
This paper considers a BMAP/M/ queue with a batch Markovian arrival process (BMAP) and an exponential service time distribution. We first prove that the BMAP/M/ que…
Design and Analysis of Deadline and Budget Constrained Autoscaling (DBCA) Algorithm for 5G Mobile Networks
Tuan Phung-Duc, Yi Ren, Jyh-Cheng Chen +1
In cloud computing paradigm, virtual resource autoscaling approaches have been intensively studied recent years. Those approaches dynamically scale in/out virtual resources to adju…
Exact Solutions for M/M/c/Setup Queues
Tuan Phung-Duc
Recently multiserver queues with setup times have been extensively studied because they have applications in power-saving data centers. The most challenging model is the M/M//Se…
Asymptotic and Numerical Analysis of Multiserver Retrial Queue with Guard Channel for Cellular Networks
Kazuki Kajiwara, Tuan Phung-Duc
This paper considers a retrial queueing model for a base station in cellular networks where fresh calls and handover calls are available. Fresh calls are initiated from the cell of…
Batch Arrival Multiserver Queue with Setup Time
Tuan Phung-Duc
Queues with setup time are extensively studied because they have application in performance evaluation of power-saving data centers. In a data center, there are a huge number of se…
Asymptotic Analysis for Markovian Queues with Two Types of Nonpersistent Retrial Customers
Tuan Phung-Duc
We consider Markovian multiserver retrial queues where a blocked customer has two opportunities for abandonment: at the moment of blocking or at the departure epoch from the orbit.…
