“…Yet, it is assumed that most updates are received in the correct order and that, in any case, it would be acceptable to recover later from possible inconsistencies. Examples of optimistic approaches available in the scientific literature are the optimistic bucket synchronization [4], the combination of local lag and Time Warp proposed in [11], the trailing state synchronization [3], and the improved Time Warp equipped with the dropping scheme and a correlation-based delivery control approach [5].…”

“…Conservative synchronization approaches allow the processing of game updates only when it is consistency-safe to do so. Lockstep [6], time-bucket synchronization [6], interactivity restoring [5], are some examples in the literature.…”

“…But it is possible to identify a a game-specific responsiveness threshold T r that represents the maximum delay allowable before providing a game update to players. The typical T r for fast-paced games (e.g., first-person shooter, racing vehicles) is 150 to 200ms, but this value can be increased to seconds in slow paced-games (e.g., strategic, role-playing games) [5,13].…”

“…fairness provision. This means guaranteeing that all players have the same chance of winning, regardless of their subjective network conditions [5]. To this aim, it should be guaranteed that all players perceive the same and simultaneous game evolution at the same time.…”

DefinitionCloud for Gaming refers to the use of cloud computing technologies to build large-scale gaming infrastructures, with the goal of improving scalability and responsiveness, improve the user's experience and enable new business models. What is cloud computing?Cloud computing is a service model where the provider offers computation and storage resources to customers on a "pay as you go" basis [12]. The essential features of a cloud computing environment are:On-demand self service: the ability to provide computing capabilities (e.g., CPU time, network storage) dynamically, as needed, without human intervention;Broad network access: resources can be accessed through the network by client platforms using standard mechanisms and protocols;Resource pooling: virtual and physical resources can be pooled and assigned dynamically to consumers, according to their demand, using a multi-tenant model;Elasticity: from the customers point of view, the provider offers unlimited resources that can be purchased in any quantity at any time;Measured service: cloud resource and service usages are optimized through a pay-per-use business model, and are monitored, controlled and reported transparently to both their customer and provider.The typical interaction between cloud provider and customer works as follows: the customer connects to a "cloud marketplace" through a Web interface, and selects the type and amount of the resources she needs (e.g., some virtual servers with given number of CPU cores, memory and disk space). The resources are allocated from a large pool that is physically hosted on some big datacenter managed by the cloud provider. Once instantiated, the resources are accessed by the customer through the network. Additional resources can be acquired at a later time, e.g., to cope with an increase of the workload, and released when no longer needed. The customer pays a price that depends on the type and amount of resources requested (e.g., CPU cores speed, memory size, disk space), and on the duration of their usage.0 The publisher version of this book chapter is available at http://dx

With the popularity of Android smart phones, all kinds of mobile online games have sprung up like mushrooms. As online card games are a kind of virtual reality simulation system which has the strong ability to create a game environment with immersive realistic scenes, online card games are getting increasingly popular and have been widely played, especially among middle-aged men. The paper introduces some key technologies for implementing a mobile online card game based on Android called Texas Hold'em Poker. The game adopts three layers of C/S model to complete the construction of the system and uses MySQL as the database. In the client, not only are some nice interfaces and animations based on 2D graphics presented, but also the steps to realize them are described in detail. Meanwhile, a multiplayer server is constructed by means of SmartFoxServer2X engine, which has a strong ability to support large-scale concurrent user access. In particular, the concepts called Lobby, Zones and Rooms are established, which allow to organize Zones into Lobby as well as organize Rooms into Zones. One Zone represents a kind of card game and one Room stands for a poker table. Programmers could develop other card games by referencing techniques written in the paper and then add them into Lobby.
