    SIMUTools 2009 is the Second International Conference on Simulation Tools and Techniques. This edition, which builds on the success of the first conference (168 participants from 31 countries), will focus on all aspects of simulation modeling and analysis. High quality papers are sought on simulation tools, methodologies, applications, and practices. The aim of the conference is to bring academic and industry researchers together with practitioners (from both the simulation community and from the numerous simulation user communities). The conference will address current and future trends in simulation techniques, models and practices, and foster interdisciplinary collaborative research in this area. While the main focus of the conference is on simulation tools, the conference also encourages the submission of broader theoretical and practical research contributions.

    • A Simulation Based Mobility Models Comparative Study

      Research Article in 2nd International ICST Conference on Simulation Tools and Techniques

      C. Joumaa, L. Moalic, S. Lamrous, A. Caminada

Simulation environment is a time variant real representation of a city based on GIS, integrating all geographical and socio-economical information relative to this city. Simulation results are the basis of the comparative analysis between the models. This comparison is made by setting metrics evaluating individual and population displacement and that by quantifying each model’s degree of realism.

    • Simulation-assisted Analysis and Design of STP-based Networks

      Research Article in 2nd International ICST Conference on Simulation Tools and Techniques

In particular, we consider both the presence and the absence of Virtual Local Area Networks (VLANs), and we derive the optimized STP parameters which minimize the STP convergence time and maximize the network stability. Two possible techniques for STP internal timers management are evaluated. The pres- ence of failures (either broken links or nodes) is also taken into account, in order to determine the proper STP parame- ters which guarantee connectivity recovery and convergence in all possible network scenarios. Some of the simulation results are also verifed through an experimental testbed. Finally, the use of ransparent" switches is proposed as a solution to (i) speed convergence, (ii) increase the reaction capability to failures, and (iii) overcome the limitations, on the maximum number of sustainable nodes, imposed by the STP. In particular, this approach allows to extend the num- ber of nodes in the network, still guaranteeing the possibility of incorporating VLANs.

    • Cable-Anchor Robot Implementation using Embedded CD++

      Research Article in 2nd International ICST Conference on Simulation Tools and Techniques

We demonstrate that a discrete-event simulation based design provides a cost-effective, flexible, open workflow for modular robotic development. The robot is designed to translate against a vertical surface using cables fixed at one end that can wind on motor-controlled spools attached to the robot. This architecture was implemented first as a regressively tested simulation within CD++ then ported to Real-time CD++. Using the NXT++ interface library, a hardware implementation of the robot using Lego® Mindstorms™ was shown to be controllable

    • A Simulation-based Approach to Highly Iterative Prototyping of Ubiquitous Computing Systems

      Research Article in 2nd International ICST Conference on Simulation Tools and Techniques

Sensor populated ubicomp environments differentiate these applications from existing mobile and distributed systems through context awareness. For the system developer, the problems of heterogeneity and scalability are felt most keenly when designing this adaptive behaviour. A context-aware ubicomp system needs to operate reliably over the wide variety of situations that may be encountered. In this paper we present a technical architecture which has been implemented to support scalable, cost-effective, runtime experimentation using a framework of models to support informed decision making in an iterative design cycle.

    • Tools for DEVS Modeling, Simulation and 3D Visualization

The CD++ Toolkit enables one to model and simulate a real or artificial system using either DEVS or Cell-DEVS. Although it is provided with a Modeler tool, this permits only 2D visualization of the simulation. This paper focuses upon two efforts to produce integrate DEVS simulations developed with the CD++ tool with 3D visualizations using Blender, an opensource 3D visualization software.
