Joint Subcarrier Allocation and Beamforming Optimization for IRS‐Assisted Multiuser MISO‐OFDMA Systems

open access: yesTransactions on Emerging Telecommunications Technologies, Volume 36, Issue 7, July 2025.
We introduce a novel model of an IRS‐assisted MU‐MISO‐OFDMA system. We aim to jointly optimize beamforming vectors, IRS reflection coefficients, and OFDM subcarrier allocation to maximize the overall sum rate. ABSTRACT In this article, we propose a novel resource allocation strategy for multiuser multiple‐input single‐output orthogonal frequency ...

Individual QoS versus aggregate QoS: a loss performance study

open access: yesIEEE/ACM Transactions on Networking, 2003
This paper explores, primarily by means of analysis, the differences that can exist between individual and aggregate loss guarantees in an environment where guarantees are only provided at an aggregate level. The focus is on understanding which traffic parameters are responsible for inducing possible deviations and to what extent.

QoS Analysis for Web Service Compositions Based on Probabilistic QoS [PDF]

open access: yes, 2011
Quality of Service (QoS) analysis and prediction for Web service compositions is an important and challenging issue in distributed computing. In existing work, QoS for service compositions is either calculated based on constant QoS values or simulated based on probabilistic QoS distributions of component services.
