Cognitive radio system and cognitive radio carrier device

A server helps a mobile phone download a large file by breaking it into pieces. Instead of the phone downloading the whole file itself, the server finds other nearby phones (collaborators) that can download parts of the file from a central storage. The server then tells these collaborator phones which parts to get, considering their network speed or how much they might charge, and these collaborator phones send their parts directly to the original phone.

Why it matters: Filed before widespread, easy-to-use mobile payment systems and robust peer-to-peer communication protocols were common. Today, micro-transaction platforms and enhanced device-to-device networking make incentivized data sharing more practical.
