We welcome you to the 13th IEEE/ACM International Symposium on Distributed Simulation and Real-Time Applications (DS-RT 2009), held this year in the heart of South-East Asia, Singapore. The island of Singapore has a long and colourful history.  For many centuries, it was controlled by the Sri Vijaya empire, with a fortified city known as Temasek (Sea Town) established in the 14th century. From that time, the island has also been known as Singapura (Lion City) after a visiting Sri Vijayan prince saw an animal he took to be a lion.


Sir Stamford Raffles established Singapore as a British trading colony in 1819 and it became an independent nation in 1965. Since independence, it has become one of the world's most prosperous countries with strong international trading links. Singapore is also a dynamic city rich in contrast and colour, where you will find a harmonious blend of culture, cuisine, arts and architecture. With its friendly and welcoming people, state-of-the-art infrastructure and spectacular events, Singapore has everything to make your stay a most memorable experience.


This year DS-RT received a large number of submissions, strengthening its status as a leading symposium in its research area.  We are also delighted that Kalyan Perumalla (Oak Ridge National Laboratory) and Steve Ellis (NASA Ames Research Center) have accepted our invitation and will provide keynote talks at the symposium.  For those interested in the history of DS-RT, the previous events in this series were held as follows:

DS-RT 2009 takes place at the Nanyang Executive Centre, located on the Yunnan Garden campus of Nanyang Technological University. We would like to thank all members of the organizing committee who have contributed in many different ways.  We are particularly grateful to Wentong Cai and Abed El Saddik, the Program Co-Chairs, for their work in organizing the technical program, Malcolm Low and Michael Lees for their help with local arrangements, Luciano Bononi and Marco Di Felice, our Webmasters, and Mirela Notare and Helen Karatza, our Publicity Chairs. We would also like to give special thanks to the program committee and outside reviewers, who provided high quality reviews of the many submissions.  Finally, we give special thanks to Silvia Ceballos and the editorial staff at IEEE Computer Society Press for their work in producing these proceedings.


Enjoy the symposium and enjoy Singapore!

DS-RT 2009 General Co-Chairs







A warm welcome to DS-RT 2009, the thirteenth IEEE/ACM Symposium on Distributed Simulation and Real-Time Applications.  We hope we have arranged an exciting program this year, with two keynote speakers who are prominent in their research areas.  Kalyan Perumalla from Oak Ridge National Laboratory will speak on "Switching to High Gear: Opportunities for Grand-scale Real-time Simulations" and Stephen R. Ellis from NASA Ames Research Center will talk about "Latency and Dynamic Fidelity in Virtual Environments". 


DS-RT 2009 targets the growing overlap between large distributed simulations and real time applications.  In particular, the regular papers this year are grouped into the following sessions: Performance and Interest Management, Interoperability and Composibility, High Level Architecture (HLA), Consistency and Latency, Virtual Reality, Disaster Management, Simulation Studies, and Real-time Applications. 


In keeping with the DS-RT tradition, a Best Paper Committee (chaired by Philip Wilsey with Michael Lees and Nick Avis as the members) will select the DS-RT 2009 Best Paper Award from the most highly ranked papers by reviewers.  The candidates for this year's best paper are (in no particular order):

Synchronised Range Queries

Vinoth Suryanaryanan, Georgios Theodoropoulos, Rob Minson

Multi-User Gaming on the Grid Using a Service Oriented HLA RTI

Pan Ke, Stephen John Turner, Wentong Cai, Zengxiang Li

An Approach for Parallel Interest Matching in Distributed Virtual Environments

Elvis S. Liu, Georgios K. Theodoropoulos

Exploring an Information Framework for Consistency Maintenance in Distributed Interactive Applications

Xin Zhang, Tomas Ward, Seamus Mcloone,

Symbiotic Simulation Control in Supply Chain of Lubricant Additive Industry

Fanchao Zeng, Stephen J Turner, Heiko Aydt

Dynamic Load Balancing Using Grid Services for HLA-Based Simulations on Large-Scale Distributed Systems

Robson Eduardo De Grande, Azzedine Boukerche


The Best Paper Award will be announced during the banquet at the conference.  On behalf of DS-RT 2008 Program Co-Chairs, we are pleased to report that the winner for the DS-RT 2008 Best Paper was "ALPHAN: A Haptic Enabled Protocol with Multi-User Collaboration" by Hussein Al Osman, Mohamad Eid, and Abdulmotaleb El Saddik.  Congratulations!


We would also like to express our appreciation to all TPC members and additional reviewers for their valuable time spent on reviewing the papers.  Particularly, we would like to thank Michael Lees for his help during the review process and Philip Wilsey for chairing the Best Paper Committee.


Hope you enjoy the Symposium and have a wonderful time in Singapore!
