This paper introduces MT-OPMNet, a multi-task deep learning framework for joint optical signal-to-noise ratio (OSNR) estimation and modulation format identification (MFI) from asynchronous amplitude histograms extracted at coherent receivers. The model combines a shared one-dimensional convolutional backbone, a channel-aware attention module and two task-specific heads for parameter-efficient inference. Validation uses a corrected nine-channel wavelength-division-multiplexed simulation dataset covering distances from 500 to 3000 km, symbol rates of 28 GBd and 64 GBd, five launch-power levels and five modulation formats. At 28 GBd, MT-OPMNet achieves an OSNR root-mean-square error of approximately 2.4 dB; over the grouped mixed-rate test split, it achieves an average OSNR RMSE of 3.4 dB and an MFI accuracy of 97.5%, while reducing trainable parameters by 23.8% relative to two separate single-task models. The analytical channel model is further cross-validated using a split-step Fourier waveform simulator, achieving mean histogram cosine similarity of 0.976 and zero-shot transfer to SSFM-generated waveforms with 100% MFI accuracy and 2.1 dB OSNR RMSE over 14–22 dB OSNR.

Attention-weight analysis shows concentration decreasing with granularity, with ProWRAS inducing a more distributed pattern that explains this trade-off.

The decoded path must satisfy clearance, no-fly-zone, altitude, segment-length and turning constraints, which makes the practical fitness landscape nonconvex, nonsmooth and strongly affected by narrow feasible corridors. This paper therefore studies UAV trajectory generation through a finite-budget derivative-free planning framework. An improved Exponential–Trigonometric Optimisation algorithm (IETO) is proposed for this real-coded UAV waypoint model. The method combines optimised Latin hypercube sampling for initial spatial coverage, adaptive exploration–exploitation control for search-radius regulation and probabilistic local refinement for terminal path improvement. Candidate paths are ranked by a nonsmooth exterior-penalty fitness and are finally accepted only after explicit decoded-path feasibility checks. Benchmark tests and deterministic, uncertain and long-range UAV scenarios show that IETO produces high-quality feasible trajectories and achieves the lowest mean planning fitness in the reported main UAV comparison under the same evaluation budget.</p>","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":"15 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ntw2.70035","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148784692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes an energy-aware hierarchical clustering framework that integrates game theory (GT) and reinforcement learning (RL) for adaptive CH selection. The GT component employs a normalised utility function incorporating residual energy, local connectivity, communication distance and expected cluster load, thereby enabling decentralised and dimensionally consistent clustering decisions. The RL component uses a compact discrete state representation, executable node-level actions, a transition-based scalar reward and off-policy Q-learning to optimise long-term energy balance, connectivity, delay and packet-delivery performance. Four configurations—full GT, full RL, GT + RL and RL + GT—are evaluated under identical simulation conditions. The proposed GT + RL framework is additionally compared with DEEC, LEACH, Q-learning-based routing and Dijkstra-based shortest-path routing using 30 paired independent runs. Among the internal configurations, full RL achieves the highest final success rate and the lowest residual-energy variance, whereas the hybrid approaches provide a favourable balance between structured decision-making and adaptability. In the external comparison, GT + RL achieves mean first-node-death, half-node-death and last-node-death values of 35.1, 63.9 and 91.1 rounds, respectively, corresponding to improvements of approximately 27.6%, 12.3% and 7.3% over the Q-learning routing baseline.

Traditional centrality-based and greedy approaches often rely on static structural assumptions and overlook community heterogeneity, behavioural credibility and adaptive optimisation. To address these limitations, this study integrates credibility-based community detection, metaheuristic optimisation, and reinforcement learning-driven parameter adaptation in a three-phase framework. Evaluated on four datasets (Caida, Cond-Mat, Douban and route views), the framework achieves 29%–68% influence spread and 11%–25% runtime reduction compared to degree centrality baselines. Ablation analysis confirms the incremental contribution of each component, demonstrating improvements from the base model (20% Caida, 3% route views) to the full model (29% Caida, 53% route views). First, type-2 fuzzy clustering combines structural and behavioural features to identify cooperative communities and prioritise credible nodes. Second, the Ali Baba and the 40 Thieves (AFT) metaheuristic selects diverse and high-impact seed nodes using a multi-criteria fitness function that balances preferential attachment, neighbourhood overlap reduction and structural similarity. Third, a reward-adaptive mechanism dynamically adjusts the fitness weights (<i>α</i>, <i>β</i> and <i>γ</i>) based on diffusion feedback, allowing the framework to adapt to varying network conditions within the tested regimes (subcritical, near-critical and supercritical). The framework is evaluated on four real-world datasets under a weighted independent cascade model across subcritical, near-critical and supercritical regimes. Compared to the IMBC baseline, the framework achieves higher influence spread across all regimes, with ablation analysis quantifying each component's contribution: base model (3%–20% spread) → full dodel (29%–68% spread), representing 1.45× to 17.67× relative improvement.</p>","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":"15 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ntw2.70034","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148752796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This raises a practical question: how large must the Laplacian regularisation weight be to certify that the eventual diffused steady state stays within a prescribed deviation from the original design? For row-stochastic and generally nonsymmetric diffusion operators, standard worst-case certificates are often conservative as they rely on global mismatch and dimensional surrogates rather than on the realised profile itself. The work derives a proof-consistent instance-adaptive certificate that combines a symmetric certificate operator, a non-symmetry remainder, a profile-dependent diagonal-mismatch term and an effective support size. The resulting expression remains closed form, supports fixed-instance inversion and one-shot pilot-based tuning, and is compatible with practically relevant nonsymmetric diffusion models. The affine diffusion model is interpreted as a graph-side mixing/restart mechanism rather than as a mass-conserving physical transport law; thus, norm stability and conservation are kept conceptually separate. The proposed framework can further be applied to a number of applications, including graph-based beamforming, wireless resource allocation and other networked diffusion settings where certified control of spread is required without repeated parameter sweeps.</p>","PeriodicalId":46240,"journal":{"name":"IET Networks","volume":"15 1","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ntw2.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148615691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
