Title : Discrete-Event Modeling and Simulation Methodologies: Applications to Wireless and Mobile Communications
Abstract :
Modeling and Simulation (M&S) techniques have received a tremendous impulse thanks to the advances in computer technology. Unfortunately, in most cases the creation of simulation models is faced with adhoc techniques. In order to improve the development task of very complex simulation systems, new methods have been proposed, and they proved to be successful in providing a sound base for the development of discrete-event simulation models, improving the ease of model definition and enhancing the application development tasks; reducing costs and favoring reuse.
The DEVS formalism is one of these techniques, which proved to be successful in providing means for modeling while reducing development complexity and costs. DEVS model development is based on a sound theoretical framework. The independence of M&S tasks made possible to run DEVS models on different environments (personal computers, parallel computers, real-time equipment, distributed simulators) and middleware.
We will present a perspective of discrete-event M&S methodologies, showing different modeling techniques. We will introduce DEVS origins and general ideas, and compare it with some of these techniques. We will then show related methods for modelling grid-shaped cellular models, which have gained popularity. We will show how to use these methods for modeling of systems whose nature is asynchronous, with a focus in wireless networks, sensor networks and mobile communication protocols. We will discuss a technological perspective to solve current M&S problems (including real-time simulation, interoperability and model-centered development techniques).

(1993) at the University of Buenos Aires, Argentina, and the Ph.D. (1998, with highest honors) at the University of Buenos Aires, Argentina, and Université d’Aix-Marseille III, France. After being Assistant Professor at the Computer Science Department of UBA, in July 2000 he joined the Department of Systems and Computer Engineering at Carleton University (Ottawa, ON, Canada), where he is now Full Professor. He has held visiting positions at the University of Arizona; LSIS (CNRS), Université Paul Cézanne, University of Nice, INRIA Sophia-Antipolis (France); UCM, UPC (Spain) and others. He is the author of three books and over 270 research articles; he edited four other books, and helped organizing over 120 conferences, including being one of the founders of SIMUTools and SimAUD. He was PI of different research projects (funded by NSERC, CFI, GRAND, MITACS, Autodesk Research, IBM, Intel, INRIA, CANARIE, Precarn, Usenix, CONICET, ANPCYT). Prof. Wainer is the Vice-President Conferences, and was a Vice-President Publications and a member of the Board of Directors of the SCS. Prof. Wainer is the Special Issues Editor of SIMULATION, member of the Editorial Board of IEEE Computing in Science and Engineering, Wireless Networks (Elsevier), Journal of Defense Modeling and Simulation (SCS), and International Journal of Simulation and Process Modelling (Inderscience). He is the head of the Advanced Real-Time Simulation lab, located at Carleton University's Centre for advanced Simulation and Visualization (VSim). He has been the recipient of various awards, including the IBM Eclipse Innovation Award, SCS Leadership Award, and various Best Paper awards. He has been awarded Carleton University's Research Achievement Award (2005-2006), the First Bernard P. Zeigler DEVS Modeling and Simulation Award, and the SCS Outstanding Professional Award (2011) and Carleton University’s Mentorship Award (2013). His current research interests are related with modelling methodologies and tools, parallel/distributed simulation and real-time systems. His e-mail and web addresses are <> and <>.
