摘要
Abstract
To solve the spectrum allocation problem in cognitive radio networks in case of the coexistence of cognitive users and authorized users, a cognitive radio spectrum allocation model based on potential game is proposed. The aim of the model is to minimize the total interference of the system. The cognitive users employ an improved dynamic policy adjustment rule (which avoids the opportunities wasting) to conduct the selection of frequency spectra, and converge to .the Nash equilibrium through finite improvement path. The simulation experiments were done in the scenario of 30 cognitive uses and 2 authorized users. The objective of the spectrum allocation with a rapid convergence speed was achieved by the algorithm. The experiment results show that the model and algorithm are feasible and effective.关键词
