A HIGH-LEVEL PETRI NET MODEL OF QUEUEING PRODUCTION SYSTEM [PDF]

Applied Computer Science, 2014
In the paper a high-level Petri model for widespread queueing networks in production systems with many customers, several queues with independent production buffers and different service nodes is presented.

Integrated service resource reservation using queueing networks theory

IET Networks, 2014
This study analyses multi‐server multi‐service queueing networks with service protection. To guarantee each service a certain quality‐of‐service and at the same time ensure high utilisation of servers, a minimum capacity is reserved each service.

Stability of queueing networks

, 2008
Queueing networks constitute a large family of stochastic models, involving jobs that enter a network, compete for service, and eventually leave the network upon completion of service.

Performance Analysis of the Sleep Mode in WiMAX 2 Networks with Multimedia Application

Journal of Applied Mathematics, 2014
We consider the sleep mode with multimedia application in WiMAX 2 networks, where the real-time traffic includes the real-time and the best-effort traffic mixed.

Capacity-Delay Trade-Off in Collaborative Hybrid Ad-Hoc Networks with Coverage Sensing

Sensors, 2017
The integration of ad hoc device-to-device (D2D) communications and open-access small cells can result in a networking paradigm called hybrid the ad hoc network, which is particularly promising in delivering delay-tolerant data.

Methods and Tools for Profiling and Control of Distributed Systems

ITM Web of Conferences, 2017
The article analyzes and standardizes methods for profiling distributed systems that focus on simulation to conduct experiments and build a graph model of the system. The theory of queueing networks is used for simulation modeling of distributed systems,

Packet-Level Modeling of Cooperative Diversity: A Queueing Network Approach

IEEE Access, 2018
Cooperative communications are expected to be a centerpiece for 5G cellular networks. Using cooperation, a wider and more uniform network coverage is attained, network capacity is enhanced, and power consumption is drastically reduced. While these latter

Biased Backpressure Routing Using Link Features and Graph Neural Networks

IEEE Transactions on Machine Learning in Communications and Networking
To reduce the latency of Backpressure (BP) routing in wireless multi-hop networks, we propose to enhance the existing shortest path-biased BP (SP-BP) and sojourn time-based backlog metrics, since they introduce no additional time step-wise signaling ...

Priority Queues with Fractional Service for Tiered Delay QoS

Future Internet, 2015
Packet scheduling is key to quality of service (QoS) capabilities of broadband wired and wireless networks. In a heterogeneous traffic environment, a comprehensive QoS packet scheduler must strike a balance between flow fairness and access delay.
