Task　scheduling　is　an　important　issue　in　Cloud　Computing.　Cloud　Computing　often　covers　a　range　of　different　kinds　of　nodes,　which　offers　a　complex　environment.　To　handle　this　complexity,　as　while　as　to　process　task　scheduling　in　different　scenarios　of　Cloud　Computing,　many　algorithms　have　been　studied.　In　this　paper,　we　propose　a　game　theory-based　algorithm　to　the　Cloud　Computing　task　scheduling　problem　on　the　principle　of　minimizing　the　cost　in　the　Cloud　Computing.　The　Cloud　Computing　task　scheduling　problem　is　treated　as　a　noncooperative　game.　The　experiment　results　demonstrate　that　the　game-based　algorithm　has　a　desirable　capability　to　reduce　the　cost　in　the　Cloud　Computing.
