By regarding all service flows at once, a session can be described by creating the optimal session configuration and several alternative ones the resources of which are(More)
In this paper we present a software architecture for traffic generation based on application level player behavior in Massively Multiplayer Online Role-Playing Games (MMORPGs). We have performed measurements of network traffic for each of the previously defined action categories for MMORPGs (Trading, Questing, Dungeons, Raiding, Player versus Player Combat,(More)
In this paper we propose ontology-based improvement of the Croa-tian Web directory search mechanism, which is currently not capable of executing queries that take into account the structure and semantics of user's query.

This paper presents an analysis of relations between player motivation and behavior in a Massively Multiplayer Online Role-Playing Game (MMORPG). We examine player behavior in terms of when, how much, and what they do in the virtual world. Player motivation is measured in terms of percentile ranks of motivational components for MMORPG players defined by(More)
A framework for multi-user distributed virtual environments (DVEs) has been proposed. The proposed framework, incorporating two models (the functional model and the interconnection model), attempts to represent the common functionality, communication issues and requirements found in multi-user DVEs. The functional model concentrates on the DVE's(More)
