Building Community and Collaboration Applications for MMOGs

Supporting collaborative activities among the online players are one of the major challenges in the area of Massively Multiplayer Online Games (MMOG), since they increase the richness of gaming experience and create more engaged communities. To this direction, our study has focused on the provision of services supporting and enhancing the players' in-game community and collaboration activities. We have designed and implemented innovative tools exploiting a game adaptation technology, namely, the In-game Graphical Insertion Technology (IGIT), which permits the addition of web-based applications without any need from the game developers to modify the game at all, nor from the game players to change their game installation. The developed tools follow a design adapted to the MMOG players' needs and are based on the latest advances on Web 2.0 technology. Their provision is performed through the core element of our system, which is the so-called Community Network Game (CNG) Server. One of the important features provided by the implemented system's underlying framework is the utilization of enhanced Peer-to-Peer (P2P) technology for the distribution of user-generated live video streams. In this paper, we focus on the architecture of the CNG Server as well as on the design and implementation of the online community and collaboration tools

A Web-Based Virtual Community

This paper describes functionality and architectural issues in the design of a web-based virtual community. This virtual community aims to meet the requirements of a virtual collaboration system with both autonomous and collaborative e-learning services, by supporting communities whose members interact and form groups based on their common interests

A Web Based Virtual Community: Functionality and Architecture Issues

A Web Based Virtual Community is an example of a Collaborative Virtual Environment, which focalizes in providing collaborative functionalities and both synchronous and asynchronous interaction services. This paper describes a virtual community, which aims to meet the requirements of a virtual collaboration space and support autonomous and collaborative e-learning services. In particular, a web-based platform is described, which is able to support communities whose members are able to interact and form groups based on their common interests. The community provides its members with the ability to communicate through enhanced forums and chats, but also, to interact in the social interaction spaces. The users can arrange events, which occur in virtual meeting centers, where 3D avatars represent the users. In these multi-user spaces, extended functionalities are offered, while system agents assist and consult the users

Management Bandwidth Service on MPLS domain

This paper describes an efficient way to implement managed bandwidth services. The proposed solution is based on MPLS technology and especially with the creation of virtual private networks. The virtual private networks will be layer 3 VPNs (IP VPNs) and are described all the mechanisms and the MPLS features that are necessary for the MBS service implementation. The paper also describes how the service will interact with the users and finally presents a schema for the interconnection with the MBS service of Geant

Services General Terms

In this paper, a technique is presented that allows web sites viewers to build personalized web pages, using specific thematic areas of their preferred sites. This technique, besides saving from the trouble of having to browse in different sites in order to find the desired content, saves users time and reduces the cost of browsing the web by minimizing the data that have to be downloaded. It is based on an algorithm, which fragments a web page in discrete fragments using the page’s internal structure. A training and update procedure is utilized for recognizing the instances of the web page components in different time points
