Analysis of Multi-Server Queueing System with Flexible Priorities

open access: yesMathematics, 2023
In this paper, a multi-server queueing system providing service to two correlated flows of requests was considered. Non-preemptive priority was granted to one flow via the preliminary delay of requests in the intermediate buffers with different rates of ...

DPCA: Data Prioritization and Capacity Assignment in Wireless Sensor Networks

open access: yesIEEE Access, 2017
Scheduling different types of data packets, such as high or low priority data packets at the sender node, is important for reducing energy and capacity consumptions and end-to-end delay.

Improvement of the Fairness of Non-Preemptive Priorities in the Transmission of Heterogeneous Traffic

open access: yesMathematics, 2020
A new flexible discipline for providing priority to one of two types of customers in a single-server queue is proposed. This discipline assumes the use of additional finite storages for each type of arriving customer.

N,n-Preemptive-Priority M/G/1 Queues with Finite and Infinite Buffers

open access: yesJournal of Applied Mathematics, 2022
In this paper, we analyze an M/G/1 priority queueing model with finite and infinite buffers under the N,n-preemptive priority discipline, under which preemption decisions are made based on the number of high-priority customers.

An Exact Schedulability Test for Real-Time Systems with Abstract Scheduler on Multiprocessor Platforms

open access: yesМоделирование и анализ информационных систем
This paper uses the model checking method for an exact schedulability test of real-time systems running on multiprocessor platforms. To use this method, we formally describe real-time systems with an abstract scheduler as Kripke models.

The Performance Analysis of SPMA Protocol in High Speed Mobile Ad Hoc Network

open access: yesIEEE Access, 2023
Aiming at the performance analysis of statistical priority-based multiple access (SPMA) protocol, the time slot transmission probability modeling method based on preemptive M/G/1 queue is pro-posed.

Fast Simulation of Networks-on-Chip with Priority-Preemptive Arbitration [PDF]

open access: yesACM Transactions on Design Automation of Electronic Systems, 2015
An increasingly time-consuming part of the design flow of on-chip multiprocessors is the simulation of the interconnect architecture. The accurate simulation of state-of-the art network-on-chip interconnects can take hours, and this process is repeated for each design iteration because it provides valuable insights on communication latencies that can ...

QUEUEING DISCIPLINES BASED ON PRIORITY MATRIX [PDF]

open access: yesНаучно-технический вестник информационных технологий, механики и оптики, 2014
The paper deals with queueing disciplines for demands of general type in queueing systems with multivendor load. A priority matrix is proposed to be used for the purpose of mathematical description of such disciplines, which represents the priority ...
