Distributed uplink rate-splitting for underwater acoustic multi-access edge computing
- Challenges in Underwater Data Processing: Collecting and processing information from submarine sensors is difficult due to severe constraints in the underwater communication environment, specifically limited bandwidth, multipath fading, and energy limitations. These factors hinder centralised data processing, particularly for applications requiring low latency.
- The work proposes a Distributed Uplink Rate-Splitting Multiple Access (DU-RSMA) framework for underwater acoustic Multi-access Edge Computing (MEC). This allows submerged sensor nodes to efficiently and reliably offload their data to cooperating surface buoys for processing.
- Surface buoys act as hybrid receivers (and form a distributed processing network. By cooperatively sharing decoded messages via low-power RF links, the buoys significantly enhance the overall capacity, offloading reliability, and physical layer security of the system.
- Improved Performance and Scalability
