Research on the design and simulation of immersive VR considering peer‐to‐peer streaming media live broadcasting algorithm

Cognitive Computation and Systems, Volume 6, Issue 4, Page 65-73, December 2024.
Abstract The utilisation of P2P tech in streaming media live broadcasting algorithm can effectively link the nodes in the endpoint and accelerate the establishment of efficient transmission channels between nodes, so as to ensure the data feasibility of video live broadcasting of terminal nodes.

Critically loaded multi-server queues with abandonments, retrials, and time-varying parameters

, 2009
In this paper, we consider modeling time-dependent multi-server queues that include abandonments and retrials. For the performance analysis of those, fluid and diffusion models called "strong approximations" have been widely used in the literature. Although they are proven to be asymptotically exact, their effectiveness as approximations in critically ...

Steam computing paradigm: Cross‐layer solutions over cloud, fog, and edge computing

IET Wireless Sensor Systems, Volume 14, Issue 5, Page 157-180, October 2024.
While fog computing mitigates some of the problems facing the achievement of prospective IoT Cyber Physical Systems (CPS) applications, fog nodes, such as edge data centres, smart gateways, and base stations may not encounter the quality level of future IoT‐ CPS applications in terms of latency, throughput, and energy constraints unless all fog, cloud,

Diffusion Limit for Single-Server Retrial Queues with Renewal Input and Outgoing Calls

, 2022
This paper studies a single-server retrial queue with two types of calls (incoming and outgoing calls). Incoming calls arrive at the server according to a renewal process, and outgoing calls of N−1 (N≥2) categories occur according to N−1 ...

Generative agent‐based modeling: an introduction and tutorial

System Dynamics Review, Volume 40, Issue 1, January/March 2024.
Abstract We discuss the emerging new opportunity for building feedback‐rich computational models of social systems using generative artificial intelligence. Referred to as generative agent‐based models (GABMs), such individual‐level models utilize large language models to represent human decision‐making in social settings.

Central Limit Theorem for an M/M/1/1 Retrial Queue with Unreliable Server and Two-Way Communication

, 2021
In this paper, we consider a single-server retrial queue with unreliable server and two-way communication. Inbound calls arrive according to a Poisson process. If the server is busy upon arrival, an incoming call joins the orbit and retries to occupy the

Optimizing Traffic at Intersections With Deep Reinforcement Learning

Journal of Engineering, Volume 2024, Issue 1, 2024.
Background: The purpose of this work is to develop a method of traffic optimization at intersections using deep reinforcement learning (DRL) by creating models for controlling autonomous vehicles and traffic lights in a simulated environment. The practical value of the research is to compare the performance of existing algorithms at both traffic light ...
