Improving the fault resilience of overlay multicast for media streaming [PDF]
, 2007 A key technical challenge for overlay multicast is that the highly dynamic multicast members can make data delivery unreliable. In this paper, we address this issue in the context of live media streaming by exploring 1) how to construct a stable ...

Row/Column-First: A Path-based Multicast Algorithm for 2D Mesh-based Network on Chips
Iranian Journal of Electrical and Electronic Engineering, 2018 In this paper, we propose a new path-based multicast algorithm that is called Row/Column-First algorithm. The proposed algorithm constructs a set of multicast paths to deliver a multicast message to all multicast destination nodes.

International Journal of Satellite Communications and Networking, Volume 44, Issue 1, Page 17-33, January/February 2026.In this paper, we investigate the application of signal‐to‐leakage‐plus‐noise ratio (SLNR) beamforming to low Earth orbit non‐terrestrial networks. The SLNR criterion aims at maximizing the received desired signal power for each user while minimizing the overall interference power caused by each user to all other co‐channel receivers. We show that such

Multiobjective Optimization for Intelligent Reflective Surface-Aided Physical-Layer Multicasting
IEEE Open Journal of the Communications Society, 2022 In this paper, we examine the use of intelligent reflective surface (IRS) to reconfigure the wireless propagation environment which assists the physical-layer multicast transmission with simple single-antenna radios in the network.

IET Communications, Volume 20, Issue 1, January/December 2026.This article presents an adaptive unmanned aerial vehicle video streaming framework in which captured video is encoded at multiple quality levels and protected using Luby transform (LT) coding before transmission over a wireless channel to a base station. At the receiver, LT decoding and latency monitoring are used to assess delivery performance, while

Bit Rate Optimization with MMSE Detector for Multicast LP-OFDM Systems
Journal of Electrical and Computer Engineering, 2012 We propose a new resource allocation algorithm with minimum mean square error (MMSE) detector for multicast linear precoded orthogonal frequency division multiplexing (LP-OFDM) systems.

IET Communications, Volume 20, Issue 1, January/December 2026.This paper proposes a 3D geometry‐based stochastic model and its beam‐domain transformation for satellite‐to‐unmanned aerial vehicle (UAV) communication channels across S to Q bands. The models capture key physical effects, including spatial consistency and atmospheric influence, while enabling efficient simulation of channel statistics under varying ...
