Evaluation and optimization of polling systems
Throughout this internship report, polling systems play a central role. Polling systems are queueing systems consisting of multiple queues, attended by a single server. The server can only serve one queue at a time. Whenever the server moves from one queue to another, a stochastic, non-zero switch-over time is incurred. The server never idles; even when there are no customers waiting in the who...
متن کاملOptimization of Polling Systems with Bernoulli Schedules
Many computer-communication networks in which the transmission right is circulated among the nodes have been modeled as polling systems. This paper concerns optimization of cyclic polling systems with respect to the service disciplines at the nodes. The service disciplines are chosen to be Bernoulli schedules. Because the optimization problem is not analytically tractable, a numerical approach ...
متن کاملAnalysis and Optimization of Polling Systems
The basic polling system is a system of multiple queues, attended to by a single server in a cyclic order. Polling systems arise naturally in the modelling of many communication, computer and production networks where several users compete for access to a common resource. Such applications also give rise to several variants of the basic polling system, like periodic polling; here the server vis...
متن کاملPerformance Evaluation of Bluetooth Polling Schemes: An Analytical Approach
In the recent years, many polling schemes for Bluetooth networks have been proposed and evaluated. To the authors knowledge, however, analysis has been carried out mainly through computer simulations and, up to now, no mathematical treatment of this topic has been presented. In this paper, we propose an analytical framework for performance evaluation of polling algorithms in Bluetooth piconets....
متن کاملTime-fixed geometry of 2nd order ODEs
Abstract : Let be a 2nd order ODE. By Cartan equivalence method, we will study the local equivalence problem under the transformations group of time-fixed coordinates. We are going to solve this problem by an applicable method which has been recognized by R. Gardner, and classify them.
