Tabu Search for Low-Cost Dynamic Multicast Tree Generation with Quality of Service Guarantees
Journal of Intelligent Systems, 2015 In a communication network with a source node, a multicast tree is defined as a tree rooted at the source node and all its leaves being recipients of the multicast originating at the source.

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.

Optimization-based congestion control for multicast communications [PDF]
IEEE Communications Magazine, 2002 Widespread deployment of multicast depends on the existence of congestion control protocols that are provably fair to unicast traffic. In this work, we present an optimization-based congestion control mechanism for single-rate multicast communication with provable fairness properties.

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.

Secrecy Rate Optimization for Secure Multicast Communications [PDF]
IEEE Journal of Selected Topics in Signal Processing, 2016 Recently, physical layer security has been recognized as a new design paradigm to provide security in wireless networks. In contrast to the existing conventional cryptographic methods, physical layer security exploits the dynamics of fading channels to enhance security of wireless communications.

Joint 2‐D LFM Modulation and Mismatched Filter Design in Dual‐Function Radar‐Communication System
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper proposes a joint 2‐D LFM modulation and mismatched filtering design for military‐grade dual‐function radar‐communication systems. The novel scheme modulates data onto both the initial frequency and chirp rate of LFM pulses, boosting data rates whilst preserving the constant‐envelope property critical for high‐power transmission.
