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
