MPSile

MPSile is a middleware framework designed to unify communication across diverse protocols in distributed Internet of Things and edge computing environments. It provides a modular, pluggable architecture that enables devices and services to exchange data through adapters for MQTT, CoAP, HTTP, AMQP, and custom protocols while exposing a single, policy-driven API to applications. The design aims to reduce integration complexity by separating application logic from transport specifics.

Its core architecture comprises a central control plane, protocol adapters, a routing and policy engine, a device registry, and a lightweight data model with a query interface. Adapters translate protocol-specific messages into a common internal representation and vice versa, enabling heterogeneous devices to interoperate. The routing engine supports topic-based and attribute-based routing, with configurable quality-of-service guarantees and offline buffering. A policy engine governs authentication, authorization, data privacy, and audit trails. The data model supports extensible schemas and lightweight data normalization to streamline analytics and storage.

History and use: MPSile originated from a collaboration among research groups and industry partners in the late 2010s, with the first public release in 2020. Since then, multiple major releases added new adapters, improved scalability, and refined security features. The project is employed in smart-city pilots, industrial automation, and remote sensor networks to standardize data ingestion, processing, and streaming across heterogeneous edge nodes. Adoption levels vary by sector, and practitioners consider trade-offs between flexibility and complexity when deploying the framework.
