Dynamic switch migration has been proposed to achieve it. However, existing schemes mainly focus on how to execute migration operation, but not why. This paper designs a decision-making mechanism based on zero-sum game theory to reelect a new controller as the master for migrated switches. It first chooses a switch for migration in the heavy controller which invites its neighbors as the game players to compete for the master role of this switch in the game-playing field(GPF) which is an occasional and loose domain for game-playing. Second, based on the concept of GPF, we design a decentralized strategy to play the game and determine which player as the final master. We implement it by extending the Open Flow protocol. Finally, numerical results demonstrate that our distributed strategy can approach elastic control plane with better performance.展开更多

It will aim to show how the use of a word reveals the intimacy of the subject, just like the autobiographical novel, which gives information about the writer. We would therefore have the presages of a self-writing in the creation, naming and storytelling of the avatar of a videogame player. From the example of a young player of the MMORPG （Massively Multiplayer Online Role Playing Games） networking game Dofus, who we met in consultation, we will see how his avatar ＂Deadlop＂ comes from parapraxis and enables the narration of his emotional intimacy. The unconscious elements that led to the creation of the pseudo enabled him to tell his story and grasp some unexplained facets of himself.展开更多

Our aim is to use human-centered modeling as a strategy for adaptive games based on entertainment measure to evaluate the playing experience. We utilized a self-organizing map (SOM) to cluster the player's style with the data obtained while playing the game. We further argued that style-based adaptation contributes to higher enjoyment, and this is reflected in our experiment using a supervised multilayered perceptron (MLP) network.展开更多
