OntoNet: Scalable Knowledge-based Middleware for Networked Systems

The OntoNet project investigates scalable, knowledge-based middleware supporting content-based addressing and routing in mobile, networked systems. It incorporates and integrates two aspects: Ontological reasoning about system resources and declarative networking within routing components. At the application layer is OntoNet, a knowledge-based framework for representing and reasoning on system elements. Declarative, formal techniques provide service discovery and composition, content-based messaging, and distributed querying using OWL-Net, a subset of the OWL description logic. This work includes development of propagation strategies that are efficient and robust in mobile, networked environments. Network layer support is provided by declarative networks, a rule-based framework for compact, high-level protocol specifications. Declarative networking enables rapid prototyping and verification as well as online adaptation and meta-reasoning. This research will include extension of declarative networking to more readily support highly dynamic mobile wireless systems.
