Cognitive radio at the other end of the spectrum [Kerry Hartnett ]
0 likes366 views
The document discusses cognitive radio technology within the context of the N4C FP7 funded research project, emphasizing its use in scenarios with unstable or absent links through Delay/Disruptive Tolerant Networks (DTN). It outlines the network infrastructure, including gateways, routers, and mules, along with their IP configurations to facilitate data transfer using available bandwidth from various radios. Key elements involve low-power, flexible communications in an atom-based system that utilizes WiMAX for short-term broadband needs over long distances.

- 2. Explanations N4C – FP7 funded research project DTN – Delay/disruptive Tolerant Networks Where to use it? where links are unstable or do not exist as we currently understand them Cognitive angle Use what bandwidth is available on what ever radio is available, e.g wifi, wimax, DTN sits under this and ensures data transfer

Cognitive Opportunities Atom based system Cognitive Systems will need to be light weight, low power, instant on, flexible comms, Atom based systems can supply this capability WiMax A wireless broad band solution that will provide bandwidth required over short time period over long distance, on/off solution Cognitive Radio over DTN
