ACM/IEEE MSWiM 2006 Go to Message from the Program Co-chairs Message from the General Co-Chairs Welcome to the 9th ACM/IEEE International Symposium on Modeling, Analysis and Simulation of Wireless and Mobile Systems (MSWiM). This year the technical program includes 51 high quality papers on wireless and mobile systems, poster and demo sessions plus two keynote addresses from well-known experts in the field. We would like to thank Prof. Alois Ferscha (Johannes Kepler Universität Linz, Austria) and Prof. George C. Polyzos (Athens University of Economics and Business, Greece) for accepting our invitation to be the keynote speakers. MSWiM 2006 also includes four tutorials on quality of service in IP for wireless systems, wireless and multimedia, future open mobile services, and WiFi versus WiMax. Besides, several workshops (MobiWAC, PE-WASUN, Q2SWinet, WMuNeP, PM²HW²N) will be hold focusing on mobility management and wireless access, security, multimedia, and heterogeneous wireless networks. Many people worked very hard to make this symposium a success. We wish to express our special thanks to the Program Co-Chairs Nael Abu-Ghazaleh and Renato Lo Cigno, and all the TPC members, for their superb job in selecting an outstanding technical program as well as the ever hard article selection process. Also, thanks to Mineo Takai for putting together a high-quality tutorial program, to Mohamed Ould-Khaoua for organizing such interesting workshops, to Sotiris Nikoletseas and Stephan Olariu for making the Poster session a successful event, to Ioannis Chatzigiannakis for organizing an exiciting Demo session, to Mirela Sechi Moretti Annoni Notare for effectively advertising the call for paper, and to Luciano Bononi for his terrific job in setting and continuously updating the web page. We would like to offer special thanks to the Local Organizing Committee (Enrique Alba, Antonio J. Nebro, Francisco Luna, Gabriel Luque, Bernabé Dorronsoro) for their dedication in organizing the symposium in such a wonderful location. Last but not least, thanks to all the external referees for providing high quality reviews within a very tight schedule. We would also like to express our gratitude to Azzedine Boukerche, the Finance and Steering Committee Chair, and to the whole MSWiM Steering Committee, who gave us the opportunity to organize this event. They have worked very hard in the past few years to establish MSWiM as the main research forum for modeling, analysing and simulating of wireless and mobile systems. Needless to say, we wish to thank our sponsors, the ACM SIGSIM and the IEEE Computer Society for their support. Finally, thanks to the speakers, session chairs and audience for attending MSWiM 2006! Enrique Alba MSWiM'06 General Co-Chair Universidad de Málaga, Spain Carla-Fabiana Chiasserini MSWiM'06 General Co-Chair Politecnico di Torino, Italy Message from the Program Co-Chairs On behalf of the Organizing Committee it is our pleasure to introduce the 9th ACM/IEEE International Symposium on Modeling Analysis and Simulation of Wireless and Mobile Systems (MSWiM 2006). MSWiM is being held this year in Terromolinos, Spain. The call for papers attracted 160 paper submissions in all areas of mobile and wireless systems. We received a large number of papers of very high quality making the selection process difficult and competitive. In the end, 39 papers were accepted as full papers (24% acceptance) and another 13 as short papers. We are very pleased with the quality of this year technical program. The submitted papers came from 50 countries, and the accepted papers from 22, reflecting the truly international nature of MSWiM. We believe that as Mobile and Wireless Systems continue to mature, increased emphasis will be placed on effective and accurate modeling, analysis and performance evaluation -the focus of MSWiM. This increased emphasis is reflected by the high number of submissions we received. We hope that the MSWiM proceedings will serve as a valuable reference for future research in the field. We have selected three outstanding papers and collected them in a single "Best Paper Contest" session (see the proceedings); the winner among these three papers will be announced at the conference dinner, and it will be reported in next year's proceedings. Last year MSWiM 2005 best paper was: "Adaptive Transmission Opportunity with Admission Control for IEEE 802.11e Networks" by A. Ksentini, A. Guéroui, M. Naimi In addition to the technical papers, the MSWiM 2006 technical program includes two distinguished keynote speakers, Prof. Alois Ferscha from University of Linz and Prof. George C. Polyzos from the Athens University of Economics and Business.. We join Enrique Alba and Carla-Fabiana Chiasserini in thanking all the people that worked so hard to make MSWiM a success. In particular, we thank the TPC members and the reviewers that offered their valuable time and expertise to provide high-quality reviews. In closing we welcome all those attending MSWiM 2006 in beautiful Terromelinos and hope that the symposium and the stay will be interesting and enjoiable, and we hope that readers who could not make it to MSWiM will consider joining it in the forthcoming editions.
