SPECTS 2009 Keynote I

Simulation and Reality: The Big Picture and Challenges

Prof. Tuncer Ören, University of Ottawa, Canada


The talk starts with a challenging view of reality and offers a comprehensive and integrative view of simulation where several seemingly different aspects are reconciled. A comprehensive view of modeling and simulation (M&S) offers the possibilities to tap its full potential and to be thorough in preparing the index of the M&S Body of Knowledge (M&S BoK). The comprehensiveness of the index of the M&S BoK is imperative in (1) designing appropriate M&S curricula and degree programs, (2) administering effective professional exams for different types of simulationists at different levels of maturity, (3) defining maturity levels of M&S establishments, and (4) finalizing the codes of a classification system for M&S industry. The Code of professional ethics for simulation practitioners and the multilingual M&S dictionary project are also highlighted. Some challenges for the profession are covered in the last part of the talk.


Dr. TUNCER ÖREN is a professor emeritus of Computer Science at the University of Ottawa, in Ottawa, Ontario, Canada. His current research activities include: (1) advanced M&S methodologies such as: multimodels, multisimulation, and emergence; (2) agent-directed simulation; (3) cognitive simulation; and (4) failure avoidance in M&S and user/system interfaces. He has also contributed to Ethics in simulation as the lead author of the Code of Professional Ethics for Simulationists, M&S Body of Knowledge, and multilingual M&S dictionaries including ontology-based systematic M&S dictionaries.

He has over 400 publications (some translated to Chinese, German and Turkish). His last book (co-edited with Dr. Levent Yilmaz) is titled: "Agent-Directed Simulation and Systems Engineering" (Wiley-Berlin). Dr. Ören has been active in over 370 conferences and seminars held in about 30 countries.

He is the founding director of the M&SNet of SCS. He has been a member of the Board of Directors of SCS for several terms and served in numerous committees. He received "Information Age Award” from the Turkish Ministry of Culture, Distinguished Service Award from SCS, and plaques and certificates of appreciation from organizations including ACM, AECL, AFCEA, and NATO. Dr. Ören is recognized by IBM Canada as a Pioneer of Computing in Canada (2005). His home page is at:

Bio-inspired and Nano-scale Molecular Communication: From Evolution to Evaluation

Prof. Ozgur B. Akan, Middle East Technical University, Ankara, Turkey


Many existing and envisioned information network architectures such as cognitive radio networks, sensor and actor networks, quantum communication networks, next generation Internet, and InterPlaNetary Internet have several common significant challenges to be addressed such as the increased complexity with large scale networks, their dynamic nature, resource constraints, heterogeneous architectures, absence or impracticality of centralized control and infrastructure, need for survivability, and unattended resolution of potential failures. These challenges have been successfully dealt with by Nature, which, as a result of millions of years of evolution, have yielded many biological systems and processes with intrinsic appealing characteristics such as adaptivity to varying environmental conditions, inherent resiliency to failures and damages, successful and collaborative operation on the basis of a limited set of rules, self-organization, survivability, and evolvability. Inspired by these characteristics, many researchers are currently engaged in modeling and developing innovative design paradigms to address the networking challenges of existing and envisioned information systems. In this talk, the current state-of-the-art in bio-inspired and nano-scale molecular communication is captured. As one of the most challenging and exciting artifacts of bio-inspired communications, nano-scale and molecular communication networks are introduced. Open research issues for the nano-scale communications are highlighted from the perspective of modeling and performance evaluation.


Ozgur B. Akan received the BS and MS degrees in electrical and electronics engineering from Bilkent University and Middle East Technical University, Ankara, Turkey, in June 1999 and January 2002, respectively. He received the PhD degree in electrical and computer engineering from the Broadband and Wireless Networking Laboratory, School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, in May 2004. He is currently Associate Professor with the Department of Electrical and Electronics Engineering, Middle East Technical University and the Director of Next generation Wireless Communications Laboratory (NWCL). His current research interests are in nano-scale and molecular communications, bio-inspired communications, next-generation wireless networks, quantum communication networks.

Dr. Akan is an Associate Editor for IEEE Transactions on Vehicular Technology, Editor for ACM/Springer Wireless Networks (WINET) Journal, and Editor for International Journal of Communication Systems (Wiley). He served as an Area Editor for AD HOC Networks Journal (Elsevier) (between 2004-2008), as a Guest Editor for several special issues. He has served as the General Co-Chair for The Third International Conference on Bio-Inspired Models of Network, Information, and Computing Systems (ICST/IEEE BIONETICS 2008), the European Vice Chair for The Second International Conference on Nano-Networks (ICST/ACM Nano-Net 2007), an International Vice Chair for IEEE INFOCOM 2006, and in organizing committees and technical program committees of many other international conferences on communications and networking. He is the Publications Committee Vice Chair for ICST and IEEE Senior Member (Communications Society). Dr. Akan received the IBM Faculty Award 2008, Turkish Academy of Sciences Distinguished Young Scientist Award 2008 (TUBA-GEBIP), the 2006 Parlar Foundation Research Encouragement Award for his research in bio-inspired communication techniques for wireless communication networks, the 2006 Editor of the Year Award from AD HOC Networks (Elsevier) Journal, the Best Paper Award in IEEE ISCN 2006, the TUBITAK-Career Award in 2005, and the 2003 Researcher of the Year Award in Broadband and Wireless Networking Laboratory, School of Electrical and Computer Engineering, Georgia Institute of Technology.

SPECTS 2009 Keynote III

Trends in QoS Provisioning in Multimedia Satellite Networks

Prof. Fatih Alagoz, Bogazici University, Istanbul, Turkey


We first introduce the basics of satellite communication systems including a generic design topology. We then focus on multimedia satellite networks, in which the forward link capacity may become a “bottleneck” operating under multimedia traffic and dynamically changing channel conditions or other anomalies. We present the system trade-offs, design objectives, and motivation for developing a proper solution algorithms for multimedia satellite networks. Then, source and channel models are described to establish an efficient and comprehensive resource allocation algorithm that maximizes the system resources while maintaining the QoS under dynamic traffic and channel conditions. While most of the research present in the literature addresses admission control and rate control independently, we show that coordination of these control mechanisms is crucial in the optimization of the overall system performance and resource management. For measures of performance, we introduce a discrete-event simulator that is utilized to quantify throughput, frame loss due to congestion during transmission as well as QoS variations due to channel and source rate changes. We present simulation results to indicate the throughput and/or quality gains when the system parameters are adjusted properly. Finally, we present open problems for improving QoS in multimedia satellite networks.
