From the abstract: "n the last decade the popularity of MMOGs has exploded. Unfortunately, the demand has far outweighed the resources commercial game providers can provide. Many MMOGs are suffering from scalability issues, resulting in game world partitioni ng, service down time and server crashes. The centralized server architecture of most modern day MMOGs is unable to cope with this increase in the number of participating players. Hence, there is a need for a scalable network architecture which can support these large number of players without affecting the overall gaming experience for each player. In this paper, we provide a review on the existing networking infrastructure solutions for MMOGs. This includes description and comparison of different im plementation techniques for the deployment of massive multiplayer on-line games, which work as a client/server and peer-to-peer paradigms. "

Abstract: "the boom of Cloud Computing services in the recent years has created new opportunities and removed many of the limitations that are typically tied to software deployed on the Internet. It has been shown that the development of online games can benefit from the integration of Cloud services into their design in order to solve many of the problems that plague their development and maintenance. In this paper, we first discuss the current designs of online gaming architectures and present their limits. The solutions offered by using Cloud services in respect to these video games are then explored and the new problems that arise from this combination are addressed. We also present a case study by deploying an online First Person Shooter multiplayer video game on currently available Cloud infrastructures (using Amazon Elastic Compute Cloud) and detailing our architecture specifically designed for this purpose. We show that, where once entering the market of online games was solely affordable by big companies due to the high infrastructure costs, a single person could now create and deploy an online game."

Abstract: "Scalability, fast response time, and low cost are of utmost importance in designing a successful massively multiplayer online game. The underlying architecture plays an important role in meeting these conditions. Peer-to-peer architectures, due to their distributed and collaborative nature, have low infrastructure costs and can achieve high scalability. They can also achieve fast response times by creating direct connections between players. However, these architectures face many challenges. Distributing a game among peers makes maintaining control over the game more complex. Peer-to-peer architectures also tend to be vulnerable to churn and cheating. Moreover, different genres of games have different requirements that should be met by the underlying architecture, rendering the task of designing a general purpose architecture harder. Many peer-to-peer gaming solutions have been proposed that utilize a range of techniques while using somewhat different and confusing terminologies. This paper presents a comprehensive overview of current peer-to-peer solutions for massively multiplayer games using a uniform terminology"

From the introduction::"The main objective of this chapter is focused on how to exploit the evolution of technology to improve user interaction in game environments through digitalized objects with identifi‐ cation technology (such as RFID or Near Field Communication). Digitalized objects are used as interaction resources. They are used in conjunction with mobile devices providing the performance of tasks with a simple and intuitive gesture. In the first place, mobile devices offer sophisticated methods to provide users with services to make use of information and to interact with objects in the real world. In the second place, physical objects are associated with digital information through identification technologies such as RFID. In this context, physical mobile interactions allow users to play games through natural interaction with ob‐ jects in the real world. This chapter has six sections. Section 2 describes some concepts such as: Ubiquitous Computing, the Internet of Things and the types of interaction used in games. Section 3 presents the general infrastructure of RFID systems. In section 4, we de‐ scribe the development of two RFID games. In section 5 their advantages and disadvantages are presented. Finally, conclusions are set out in Section 6."

From the abstract: "In Northern Ireland a Virtual Learning Environment (VLE) infrastructure is in place. However, statistics and government reports suggest that VLE use amongst the primary school sector is quite limited. In an attempt to redress the limited use of VLEs in the primary school sector this research investigates the potential of serious games and how they may compliment the National Curriculum with the development of AmbiLearn, an enhanced learning environment with a content neutral game-based approach and content creation and reporting modules. This paper presents the design and implementation of AmbiLearn. Preliminary analysis of data from evaluation of AmbiLearn shows promising results and directions for future work are discussed."

Abstract: "The main goal of this research is to understand how Utrecht's business environment must be developed in order to increase the region's international competiveness in the gaming industry. Utrecht's aim is to specialize in the gaming industry. In this research it is estimated that Utrecht is focused on small digital development game companies. The results indicate that Utrecht's competitive advantages are in its policy intervention, low labor wages and real estate costs, well developed demographical factors and infrastructure compared to the other investigated European cities. However, Utrecht scores below average on the categories of investments, quality of life and human resources. Once Utrecht has a stronger promotional effort in the gaming industry, it enlarges its attraction to draw game companies and to better its international position."

Abstract: "Mobile gaming is a big driver of app marketplaces. However, few mobile games deliver truly distinctive gameplay experi- ences for ad hoc collocated users. As an example of such an experience, consider a sword ght dual between two users facing each other where each user's phone simulates a sword. With phone in hand, the users' thrusts and blocks translate to attacks and counterattacks in the game. Such Phone-to- Phone Mobile Motion Games (MMG) represent interesting and novel gameplay for ad hoc users in the same location. One enabler for anMMG game like sword ght is continuous, accurate distance ranging. Existing ranging schemes cannot meet the stringent requirements of MMG games: speed, ac- curacy and noise robustness. In this work, we design FAR, a new ranging scheme that can localize at 12Hz with 2cm median error while withstanding up to 0dB noise, multipath and Doppler eect issues. Our implementation runs on com- modity smartphones and does not require any external in- frastructure. Moreover, distance measurement accuracy is comparable to that of Kinect, a xed-infrastructure motion capture system. Evaluation on users playing two prototype games indicate that FAR can fully support dynamic game motion in real-time."

"What we want to make sure, when the next wave builds, that people see that there's an infrastructure already in place in Worcester,'' McGovern said. "We want this to be the video gaming corridor of not only the Northeast, but the country.''
