Green Distributed Power Control Algorithm for Multi-user Cognitive Radio Networksd. Simple utility function and time back-off are utilized to facilitate the implementation of distributed algorithm. Simulations show that the proposed algorithm improves the system EE as Pareto improvement is reached. Meanwhile, primary user’s QoS is guaranteed as secondary users transmit with lower power.

Optimal Channel Selection and Power Control over D2D Communications Based Cognitive Radio Networkscheme in D2D communications based cognitive radio networks. The extensive simulation results obtained validate our developed joint channel selection and power control scheme. We also show that our developed scheme can significantly increase the average peak signal-to-noise ratio (PSNR) as compared with the existing research works.

Without relying on dedicated wireless power transfer, in our system the source is powered by salvaging energy from the relaying signals. In this network, RS will affect both the

Our goal is, under this condition, to develop a dynamic power control policy for the transmitter such that the time average throughput of the system is maximized over an infinite horizon,

We model the interaction between the relay and the destinations as a Stackelberg game and then study the joint utility maximization of the relay and the destination. The Stack
