Resource Allocation in Hybrid Radio-Optical IoT Networks using GNN with Multi-task Learning

arXiv — cs.LGWednesday, November 12, 2025 at 5:00:00 AM
The recent publication titled 'Resource Allocation in Hybrid Radio-Optical IoT Networks using GNN with Multi-task Learning' introduces a novel approach to dual-technology scheduling in IoT networks that integrate Optical Wireless Communication (OWC) and Radio Frequency (RF). The authors tackle the complex problem using a Mixed-Integer Nonlinear Programming (MINLP) model aimed at maximizing throughput while minimizing delays, constrained by energy and link availability. Given the challenges of solving NP-hard problems at scale, they propose the Dual-Graph Embedding with Transformer (DGET) framework, which combines transductive and inductive Graph Neural Networks (GNNs) for effective scheduling. Simulation results indicate that hybrid RF-OWC networks outperform traditional methods, highlighting the potential of this framework to enhance IoT network performance. This work is particularly relevant as the demand for efficient resource allocation in IoT systems continues to grow, making adva…

Enhancing Graph Representations with Neighborhood-Contextualized Message-Passing
PositiveArtificial Intelligence
Graph neural networks (GNNs) are essential for analyzing relational data, categorized into convolutional, attentional, and message-passing variants. The standard message-passing approach, while expressive, overlooks the rich contextual information from the broader local neighborhood, limiting its ability to learn complex relationships. This article introduces a new framework called neighborhood-contextualized message-passing (NCMP) to address this limitation, enhancing the expressivity and efficiency of GNNs.

Heterogeneous Attributed Graph Learning via Neighborhood-Aware Star Kernels
PositiveArtificial Intelligence
The article presents the Neighborhood-Aware Star Kernel (NASK), a new graph kernel for attributed graph learning. Attributed graphs, which feature irregular topologies and a mix of numerical and categorical attributes, are prevalent in areas like social networks and bioinformatics. NASK utilizes an exponential transformation of the Gower similarity coefficient to efficiently model these attributes and incorporates multi-scale neighborhood structural information through star substructures enhanced by Weisfeiler-Lehman iterations. The theoretical proof confirms that NASK is positive definite.
