Data Delivery in Challenging Environments
Oceans Niagara focuses on communications resilience for autonomous machines and distributed systems operating across Disconnected, Intermittent, and Low-Bandwidth (DDIL) networks.
Labs: Zero-Retransmission Asset Sync
In large-scale field deployments—such as agricultural robotics, autonomous turf machinery, environmental sensor grids, and industrial rovers—patchy wireless links cause sustained packet loss. Standard acknowledgment-based protocols (TCP or ARQ pub/sub) trigger severe ACK/NACK storms when broadcasting large binary payloads to multiple nodes over constrained links.
We are prototyping a zero-retransmission distribution pipeline pairing Eclipse Zenoh with RaptorQ (RFC 6330) forward error correction. By streaming rateless mathematical droplets rather than sequential chunks, edge nodes can reconstruct full operational assets—such as runtime configurations, perception bounds, state models, or WASM execution routines—from any random subset of broadcast packets.

Core Architecture Pillars
Rateless Erasure Coding
RaptorQ fountain codes eliminate acknowledgment overhead. Receivers reconstruct complete binary payloads from any valid subset of droplets caught.
Self-Describing OTI
Every packet carries a 22-byte metadata prefix, ensuring drops of initial stream headers never prevent full recovery.
Content-Addressed Integrity
Payloads are verified against cryptographic SHA-256 Content Identifiers (CIDs) and AEAD transit encryption before execution, preventing corrupt state from reaching machine hardware.
Decentralized Pub/Sub
Leverages Eclipse Zenoh for unified telemetry, remote commands, and inter-peer cache repair across ad-hoc radio meshes.
Atomic Edge Staging
Crash-proof append operations with explicit fsync boundaries protect edge nodes against sudden field power loss.
