In today's IoT environment, edge-resident AI agents are increasingly spread across home servers, IoT hubs, laptops, and phones. However, their coordination stacks still rely on cloud-style transports or central relays. We introduce EdgeCitadel, an edge multi-agent orchestration platform built around a single NATS 2.10 server with a built-in MQTT adapter.
This design combines MQTT connectivity to support heterogeneous agents, JetStream-backed persistence and replay for backend services, direct peer delegation over a shared subject namespace, and a passive aggregator that visualizes and stores traffic without interfering with the delivery path.
Our poster highlights the migration from MQTT relay prototypes, common in IoT communication, to the current hybrid architecture and demonstrates a working cross-device testbed spanning ARM64, x64, and Android clients.
Blogger's Review: The design of EdgeCitadel exemplifies the perfect integration of edge computing and multi-agent systems, leveraging the strengths of both MQTT and NATS to significantly enhance inter-device collaboration, especially in heterogeneous environments. This platform offers new insights and technical support for future edge computing applications.
