Malgré leurs propriétés attrayantes, les environnements virtuels en réseau (net-VE) sont notoirement difficiles à concevoir, à mettre en œuvre et à tester en raison des fonctionnalités de concurrence, de temps réel et de mise en réseau de ces systèmes. La pratique actuelle en matière de conception de net-VE repose essentiellement sur des essais et des erreurs, empiriques et manque totalement de méthodes formelles. Cet article propose d'appliquer une technique de modélisation formelle de réseau de Petri à un net-VE : NICE (Narrative Immersive Constructionist/Collaborative Environment), de prédire les performances du net-VE sur la base de la simulation et d'améliorer les performances du net-VE. NICE est essentiellement un réseau de systèmes de réalité virtuelle collaboratifs appelé GROTTE-(Environnement virtuel automatique CAVE). Tout d’abord, nous présentons les modèles étendus de réseaux de Petri à timing flou de CAVE et NICE. Ensuite, en utilisant ces modèles et Design/CPN comme outil de simulation, nous avons réalisé diverses simulations pour étudier le comportement en temps réel, les effets de réseau et les performances (latences et gigue) de NICE. Nos résultats de simulation sont cohérents avec les données expérimentales.

Abstract: Despite their attractive properties, networked virtual environments (net-VEs) are notoriously difficult to design, implement and test due to the concurrency, real-time and networking features in these systems. The current practice for net-VE design is basically trial and error, empirical, and totally lacks formal methods. This paper proposes to apply a Petri net formal modeling technique to a net-VE: NICE (Narrative Immersive Constructionist/Collaborative Environment), predict the net-VE performance based on simulation, and improve the net-VE performance. NICE is essentially a network of collaborative virtual reality systems called CAVE-(CAVE Automatic Virtual Environment). First, we present extended fuzzy-timing Petri net models of both CAVE and NICE. Then, by using these models and Design/CPN as the simulation tool, we have conducted various simulations to study real-time behavior, network effects and performance (latencies and jitters) of NICE. Our simulation results are consistent with experimental data.
