    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.

    • Visual tracking using Sensor Networks

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

      Paolo Pagano, Francesco Piga, Giuseppe Lipari, Yao Liang

      In this domain, at the design stage, particular attention must be devoted to individual data packets as those entities carrying unique (not redundant) information. The performances of the deployed system (hereby felt as a black box) must be tracked against the reliability and timeliness offered in message delivery.

      A Visual Tracking case study is discussed throughout this paper with the support of a simulation package modelling real-time scheduling policies at the device node kernels and bandwidth allocation techniques for network reliable communications as standardized in the IEEE 802.15.4 suite of protocols.
      A set of results is carried out estimating the performances of the Visual Tracking system in two contexts (those of a monitored junction in an airport taxiway and in a parking area) very different for criticality and average volume of network traffic.

    • Modelling chronicle recognition for distributed simulation processing with coloured Petri nets

For instance, an airport ground traffic simulation requires to model the planes with the pilots, the control tower, the weather, etc. together with their interactions, e.g. the communications between the pilots and the control tower (authorizations and acknowledgements), the weather impact on the routing rules, etc.

    • DEUS: a Discrete Event Universal Simulator

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

      Michele Amoretti, Matteo Agosti, Francesco Zanichelli

In this paper we introduce our novel general purpose simulator, called DEUS, which aims at becoming one of the reference tools in the field of complex system simulation. Its essential Java API provides basic interfaces and classes for modelling nodes, events and processes characterizing the structure and dynamics of any complex system. High usability, configurability and memory efficiency are among the strengths of DEUS, as exemplified in this paper by means of the simulator of Chord peer-to-peer systems we implemented with minor coding effort.

    • ns-2 Distributed Clients Emulation: Accuracy and Scalability

Real-time constraints and the boundary be- tween real-world and simulated entities impose scal- ability and accuracy limitations, and distort the sim- ulated network as perceived by the involved real- world applications. This paper presents results from a performance evaluation of the ns-2 emulation fa- cility. Conducting emulation experiments of differ- ing magnitudes, and under varying emulation envi- ronment set-ups, we unveil central types of scala- bility limitations and obtainable accuracy. We find throughput limits using high and low end comput- ers, and a significant throughput decrease when in- creasing the number of involved real-world applica- tions. We furthermore show how end-to-end delay increases both with traffic load and an increasing number of involved real-world applications. More- over, during these conditions, we find that the sys- tem treats these applications increasingly unfair by distributing total throughput unevenly between them, and by imposing different amounts of end-to-end de- lay.

    • Simulation and Analysis of a Combined Mobility Model with Obstacles

The simulation environment deeply influences the behaviour of results, so a model that simulates a realistic movement of the nodes is necessary for the study of wireless networks. Simple mobility models do not provide realistic scenarios. Often movements are completely random, uncorrelated and in open space, without the chance of considering the effects of obstacles or rules that limit and guide the movement. In this paper, we propose a more realistic mobility model, studied for indoor environments (but applicable to outdoor models as well). Given the map of the obstacles in the simulation area (e.g. a floor plan), the nodes have the possibility to move in random walk just avoiding to cross the obstacles (e.g. walls), or following a specified virtual path that connects all the simulation area, or a hybrid of the two. Our tool creates a file containing the movement of the nodes during the whole simulation time. Simulation results show that nodes are highly dependent on the different obstacles maps and pathways. Furthermore, a mathematical demonstration is given to validate the results obtained by simulation in a simple case.
