Many queueing systems are subject to time-dependent changes in system parameters, such
as the arrival rate or number of servers. Examples include time-dependent call volumes and …

Trust establishment in vehicular ad hoc networks (VANETs) is a challenging task due
essentially to the high speed of vehicles, the long distances, and the network topology …

It has been recently observed that Software Defined Networks (SDN) can change the paths
of different connections in the network at a relatively frequent pace to improve the overall …

This paper illustrates a computable matrix technique that can be used to derive explicit
expressions for the transient state probabilities of a finite waiting space single-server queue …

In this paper, we consider a single server Markovian queueing system with a finite buffer. In
addition to a Poisson stream of positive arrivals we assume that there is a also a Poisson …

We consider ordinary and conditional first passage times in a general birth–death process.
Under existence conditions, we derive closed-form expressions for the k th order moment of …

The transient behaviour of single server bulk queues with finite-buffer capacity is discussed
numerically under the assumption that the server may take multiple working vacations after …

Queueing theory is a useful tool in design of computer networks and their performance
evaluation. The literature concerning this subject is abundant. However, it is in general …

In multi-access systems, scheduling mechanism often requires a proper feedback policy. In
this paper, the direct and simple transient solution technique for the state of the system in a …

The increasing use of Software-Defined Networks brings the need for their performance
analysis and detailed analytical and numerical models of them. The primary element of such …
