    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.

    • Atarraya: a simulation tool to teach and research topology control algorithms for wireless sensor networks

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

      Pedro M. Wightman, Miguel A. Labrador

Despite the fact that topology control algorithms and protocols have been extensively studied, they are currently unavailable in most, if not all, simulation tools. In this work we introduce Atarraya, a discrete-event simulation tool specifically designed for testing and implementing topology control protocols for wireless sensor networks. The simulation tool includes structures for designing both topology construction and topology maintenance protocols. In addition, Atarraya includes several key algorithms and applications that along with its graphical user interface can be used to support teaching activities. The correctness of the tool is validated using well-known results available in the literature.

    • COOJA/MSPSim: interoperability testing for wireless sensor networks

Interoperability testing is performed today through black-box testing with vendors physically meeting to test their equipment. Black-box testing can test interoperability but gives no detailed information of the internals in the nodes during the testing. Blackbox testing is required because existing simulators cannot simultaneously simulate sensor nodes with different firmware. For standards such as IP and WirelessHART, a white-box interoperability testing approach is desired, since it gives details on both performance and clues about why tests succeeded or failed. To allow white-box testing, we propose a simulation-based approach to interoperability testing, where the firmware from different vendors is run in the same simulator.

      We extend our MSPSim emulator and COOJA wireless sensor network simulator to support interoperable simulation of sensor nodes with firmware from different vendors. To demonstrate both cross-vendor interoperability and the benefits of white-box interoperability testing, we run the state-of-the-art Contiki and TinyOS operating systems in a single simulation. Because of the white-box testing, we can do performance measurement and power profiling over both operating systems.

    • A java simulation tool for fixed-point system design

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

However, the task is widely acknowledged to be tedious, error prone, and time consuming. In this paper, we propose a systematic approach to automate fixed-point system design. The technique generates fixed-point parameters that satisfy a precision constraint imposed on the primary output of the algorithm to be realised. The development of a simulation framework based on this analysis allows fixed-point designs to be generated in a shorter time frame. The effectiveness of the approach and framework is demonstrated through the implementation of an Erbium-Doped Fibre Amplifier (EDFA) control algorithm in fixed-point.

    • Tools for dependent simulation input with copulas

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

Together with the marginal distributions of the vector elements, they define a multivariate distribution which can be used to generate random vectors with this distribution. A toolbox is presented which implements input models with this method, for random vectors and time series. Time series are modeled with some general autoregressive processes. The copulas are estimated from observed samples of random vectors. The MATLAB tool calculates the copula, generates random vectors and time series, and provides statistics and diagrams which indicate validity and accuracy of the input model. It is fast and allows for random vectors with high dimensions, for example 100. For this efficiency an intricate data structure is essential. The generation algorithm is also implemented with Java methods.

    • Improving Lagrangian methods: toward an agent-particle based method

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

The procedure suggests, for avoiding some of the Lagrangian methods limitations, to replace the classical particle with an autonomous process -- an agent-particle: AP -- able to implement skills like vicinity perception, capacity of evaluating mutual contribution, testing complex behaviors… A complete description of concepts and tools that the AP-based method might use for limiting the combinatory complexity is first given; sending messages for symmetric contributions, quad-Lattices for neighbors searching, ray tracing and kd-tree-domains for handling obstacles… In a second part, a continuous convection-diffusion problem and a discrete animals aggregation are simulated to show what the AP-based method can bring to classical resolution schemes.
