Low energy consumption multicast scheme for D2D multicast in wireless cellular network
Dianzi Jishu Yingyong, 2019 This work studies the effective multicast of data from base station to multiple devices in a small area, and proposes a fixed-relay based multicast scheme and a dynamic-relay based multicast scheme.

Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems
International Journal of Satellite Communications and Networking, Volume 44, Issue 3, Page 275-287, May/June 2026.ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

VMCast: A VM-Assisted Stability Enhancing Solution for Tree-Based Overlay Multicast. [PDF]
PLoS ONE, 2015 Tree-based overlay multicast is an effective group communication method for media streaming applications. However, a group member's departure causes all of its descendants to be disconnected from the multicast tree for some time, which results in poor ...

3D As‐Built Environments in Extended Reality Applications: A Systematic Review
The Photogrammetric Record, Volume 41, Issue 194, April/June 2026.This systematic review identifies BIM and game engines as the primary tools for integrating 3D as‐built environments into XR. While multi‐sensor fusion and multimodal interaction enhance immersion, persistent challenges like manual modeling and bandwidth limitations continue to hinder full ecosystem maturation.

An Optical Multicast Routing with Minimal Network Coding Operations in WDM Networks
International Journal of Optics, 2014 Network coding can improve the optical multicast routing performance in terms of network throughput, bandwidth utilization, and traffic load balance. But network coding needs high encoding operations costs in all-optical WDM networks due to shortage of ...

Proceedings 7th International Conference on Computer Communications and Networks (Cat. No.98EX226), 2002 We present a new scalable fault-tolerant algorithm which ensures total order delivery of messages sent to multiple groups of processes. Our algorithm is particularly well suited for large scale systems because: (1) any process can multicast a message to one or more groups of processes without being forced to join those groups; (2) inter-group total ...

IDLB: An SDN‐Based Load‐Balancing Routing Protocol for Autonomous Satellite Constellation Networks
International Journal of Satellite Communications and Networking, Volume 44, Issue 2, Page 109-127, March/April 2026.ABSTRACT Routing in satellite constellation networks with intersatellite links has become an important aspect to enable broadband Internet access and to integrate into terrestrial networks. However, their dynamic characteristics and large physical size require specifically tailored solutions.

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

IET Cyber-Physical Systems: Theory &Applications, Volume 11, Issue 1, January/December 2026.Recent proposals by Mahmood et al., Braeken et al., and Chaudhry et al. aimed at establishing secure communication in AMI, asserting their methods fulfil the requisite security criteria. This paper, however, reveals that each of these proposals exhibits security vulnerabilities and lacks sufficient features for deployment.
