Game theory-based cognitive radio dynamic spectrum allocation, is one of the hot researches of the field of cognitive radio. Taking into account the differences in the spectrum, using a Cournot game model, and adding the spectral similarity matrix to the original pricing function, a new utility function that makes the spectrum allocation more close to the actual network environment is proposed. Simulation...
The current fixed spectrum allocation scheme leads to low spectrum utilization across the whole spectrum. It requires some more effective spectrum allocation and utilization policy, which allows unused parts of spectrum to become available temporarily for other usage, so that the scarcity of the spectrum can be largely mitigated. Taking the cognitive user's service demand into account, we improve...
Aiming at the power control in cognitive radio, a power control game algorithm based on interference temperature is discussed, and non-cooperative power control game which is created by David Goodman is used. The efficiency function was mended, and we also designed a new pricing function with interference temperature. Compared with other power control game models, the simulation shows that the NPG-ITLP...
