CogNet – Cognitive Networking Rutgers University, University of Kansas, Carnegie Mellon University The Global Control Plane and Architecture Internetworking Innovative Ideas Name & Service Discovery Cross-Layer Aware Routing Forwarding Incentives Network Management Architecture Future Internet Network Layer Protocols Supernode (mobile or fixed) Spectrum Coordination Flexible MAC Layer PHY Adaptation Cognitive Radio Nodes Autoconfiguration and Bootstrapping Protocols • Cognitive and collaborative – applying the experience gathered in one place by one being to actions by another being elsewhere • Scalable autoconfiguration and network management • Dynamic network layer supporting tailored functionality – use IP, group messaging, rich queries, etc. as appropriate • Builds on and extends cognitive radios Impact Project Plans • Developing experimental protocol stack for cognitive networks • Explore how having tailored network layers – e.g., IP, range-based overlays, multicast optimized overlays, etc. – may impact end-to-end network architecture for interoperating cognitive wireless subnets and the future Internet • Develop algorithms to use, position, and discover gateways between the overlays themselves, and beyond • Develop algorithms for applications to decide (e.g., GCP) which network layer to use • Implement multiple new network layers • Explore performance tradeoffs (e.g., more overhead versus better utilization) in simulation & real cognitive radio network Joseph B.
