DEVELOPMENT AND IMPLEMENTATION OF A DIVERSIFIED, SELF-DIRECTED TALENT DEVELOPMENT MODEL FOR COMMUNICATION ENGINEERING UNDER EMERGING ENGINEERING EDUCATION

With the extensive deployment of 5G and forward-looking research and development on 6G, the intelligent transformation of the communication industry is placing higher demands on engineering education. Conventional Communication Engineering programs still face fragmented curricula, delayed integration of emerging techno...

Spectral Efficiency Maximization for STAR-RIS-Assisted mmWave-NOMA Downlink Communication Systems

Simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) can reconstruct indirect links when the direct link is blocked for millimeter wave (mmWave) communications. Moreover, the spectral efficiency of non-orthogonal multiple access (NOMA) can benefit from the highly directional transmis...

Stable Implicit Conditioning With Residual Statistics for Multivariate Time-Series Anomaly Detection in Industrial IoT Monitoring

Timely anomaly detection in Industrial Internet of Things (IIoT) monitoring requires robust modeling of noisy multivariate sensor streams. Although decomposition-derived residuals provide a potentially useful auxiliary view for multivariate time-series anomaly detection (MTSAD), they are not clean anomaly surrogates in...

DREAM: A Dynamic Ripple-Effect-Aware Meta-Scheduling Scheme for Cloud-Edge-End Collaborative AI Computing

Cloud-edge-end collaborative Artificial Intelligence (AI) computing requires schedulers that allocate heterogeneous resources for Directed Acyclic Graph (DAG)-structured workflows across network tiers. Cross-tier data transfers create ripple effects where a single placement decision propagates delays to downstream task...

GNN-OSS: A Capacity-Feasible Graph Learning Framework for Secure Blockchain Sharding in IIoT

Effective scaling of blockchain-enabled Industrial Internet of Things (IIoT) requires sharding that simultaneously ensures transaction locality, strict committee-size feasibility, and robustness against malicious node concentration. Existing methods often fail to balance this trilemma, risking either infeasible deploym...

Low-Energy Resource Optimization and Task Assignment for Satellite Edge Computing Networks

Satellite edge computing (SEC) has emerged as a promising paradigm to enhance in-orbit data processing capabilities and reduce transmission latency. However, satellite image processing tasks in SEC environments face critical challenges in efficient data handling, resource coordination, and transmission scheduling. The...
