Poster: EdgeCitadel -- Hybrid NATS-MQTT Orchestration for Edge Multi-Agent Systems

EdgeCitadel is a newly proposed hybrid orchestration platform for edge multi-agent systems, utilizing a single NATS 2.10 server with an integrated MQTT adapter. It offers MQTT connectivity for diverse agents, JetStream-backed persistence for backend services, and a passive aggregator for traffic visualization and storage. This architecture addresses the limitations of traditional cloud-based coordination by enabling direct peer delegation and cross-device communication across ARM64, x64, and Android clients, which is significant for practitioners developing decentralized IoT solutions.
