JADE is a Java-based agent development framework that simplifies the creation of distributed multi-agent systems. It provides FIPA-compliant infrastructure including a runtime environment, message transport, directory facilitator, and agent management. Developers write agent classes in Java, deploy them in containers, and use graphical tools like RMA and Sniffer for debugging and monitoring. JADE supports agent mobility, behavior scheduling, and lifecycle operations, enabling scalable and modular designs for research, IoT coordination, simulations, and enterprise automation.
