The invention discloses a distributed base station clustering method based on the hedonic game. Base stations are clustered using the game theory. From the perspective of the game theory, the process in which base stations form a stable cluster by dynamically adjusting the cluster structure thereof is a game. In a hedonic game model, base stations are rational game players. An appropriate preference function is defined. Base stations make decisions in line with their own interests by calculating the preference value. Finally, individual equilibrium is achieved, and a stable cluster is obtained. Compared with a heuristic method, the method has a great advantage in performance. Compared with a clustering method based on the ergodic thought, the method is much less complex under the premise of little difference in performance.
