The development and evaluation of a proper mobility model is an essential feature to evaluate a system that manages a virtual world. In distributed virtual environments, this is also more important because each avatar requires a consistent view of the world that usually is splitted on multiple machines. Several models have been proposed in the literature to describe avatars' mobility, but a single environment supporting the generation of traces from dierent models to enable a simple comparison of them is still lacking. In this work we present a tool that implements popular mobility models and supports the generation of traces generated by them. This may help developers to easily validate their systems using several mobility models. Our tool provides a unied format to describe the traces, enables the generatation of traces for thousands of avatars and denes an API enabling the integration of additional models.

Abstract
The development and evaluation of a proper mobility model is an essential feature to evaluate a system that manages a virtual world. In distributed virtual environments, this is also more important because each avatar requires a consistent view of the world that usually is splitted on multiple machines. Several models have been proposed in the literature to describe avatars' mobility, but a single environment supporting the generation of traces from dierent models to enable a simple comparison of them is still lacking. In this work we present a tool that implements popular mobility models and supports the generation of traces generated by them. This may help developers to easily validate their systems using several mobility models. Our tool provides a unied format to describe the traces, enables the generatation of traces for thousands of avatars and denes an API enabling the integration of additional models.File | Dimensione | Formato | |
