This paper studies the problem of distributed spectrum/channel access for cognitive radio-enabled unmanned aerial vehicles (CUAVs) that overlay upon primary channels. Under the framework of cooperative spectrum sensing and opportunistic transmission. a one-shot optimization problem for channel allocation. aiming to maximize the expected cumulative weighted reward of multiple CUAVs. https://www.markbroyard.com/best-flash-pp-aluminum-lotion-pump-supply-amazing-save/
