This paper provides the development of green game idea procedures for spectrum sharing in upcoming 6G cellular networks. As dynamic spectrum get entry to keeps to advantage commercial interest, the want to broaden a sustainable framework to make sure powerful and relaxed spectrum sharing arises. To this stop, sport principle methods are seen as a legitimate candidate to facilitate robust spectrum sharing in 6G networks. This paper offers unique attention to the area of spectrum sharing and how the underlying game theory procedures may be leveraged to percentage spectrum efficiently. After an intensive review of existing methods and strategies, an overall performance evaluation of the numerous strategies is provided. Subsequently, the paper gives insights at the potential of game concept strategies in future 6G networks. Moreover, much game theoretic equipment are used for analytical as well as simulation experiments if you want to higher apprehend the dynamics of the spectrum sharing. Basic, this paper examines the effectiveness of each analytical and simulation-based totally game theoretic fashions for spectrum sharing in 6G networks, and gives a new version which may be used to improve the spectrum sharing dynamics in such networks.
