A framework for mobile-agents embodied in X3D networked virtual environment

ABSTRACT

In this paper we present a VRML oriented framework that aims to capture the key notions that underlie the extension of X3D toward multiuser and autonomous creatures. Our results can be understood in two ways. One can view the structure of the framework as an effort to identify general concepts with special emphasis on separation of concerns, that is to say, as a design pattern. One can also view the framework as a glue between the most recent technologies involved in the implementation of a Networked Virtual Environment : generic content management, advanced group communication protocols and mobile computing.
