Researchers propose S²C²I-integrated high-altitude platforms for next-gen networks
High-altitude platforms could unify sensing, storage, and AI for emergency response networks
High-altitude platforms are emerging as persistent middle-layer infrastructure for space-air-ground integrated networks — and their role is expanding beyond communication relaying toward the joint provision of sensing, storage, communication, computing, and intelligence (S²C²I). This survey presents a unified HAP-centric perspective on that integration, covering architectures, cross-functional design, evaluation, and deployment. A case study on emergency response shows that jointly orchestrating all of these capabilities substantially improves conjunctive service availability while reducing feeder-link traffic.
- Proposes S²C²I integration (sensing, storage, communication, computing, intelligence) in high-altitude platforms (HAPs) for space-air-ground networks
- Architecture includes heterogeneous links (RF, mmWave, THz, FSO) and AI-driven orchestration, validated via a four-level evaluation framework
- Case study shows 50% reduction in feeder-link traffic and 40% improvement in service availability for emergency response
