Abstract—Medical multimedia data transmission for remote diagnosis and emergency incident reports will significantly increase in the coming years. Thus, broad-band network technologies with ability to be adaptable to user’s context and application content must be considered. In this paper, we propose an on-the-fly resource reservation protocol for medical multimedia content delivery in cognitive radio networks. Our ap-proach is based on an appropriate channels switching, that meets the need of end-to-end video quality and throughput requirements for better clinicians analysis. When a channel switching must be performed, an appropriate channel is reserved. This process will also rely on a signalling protocol which allows transmitting traffic characteristics and required network resources to all relay nodes for a best decision-making. I.
