W4S
w4S is a modular open-source software framework designed to enable secure data synchronization, transformation, and routing across distributed systems, with particular relevance to sensor networks, edge devices, and microservice architectures. It aims to provide a unifying runtime that can connect heterogeneous data sources and transport layers while preserving data integrity and privacy.
The architecture centers on a lightweight core runtime, a messaging protocol, and a set of pluggable adapters
Key features include end-to-end encryption, identity and access management, audit logging, offline operation with reconciliation, schema
Use cases in industry include IoT data aggregation, distributed analytics, and edge-to-cloud data sharing. Academic researchers
