Proceedings of the 2009 International Conference on Wireless Communications and Mobile Computing: Connecting the World Wirelessly

Welcome to the ACM International Wireless Communications and Mobile Computing Conference (IWCMC 2009) with the theme this year of "Connecting the world wirelessly." This year's Conference continues its tradition of being the premier forum for presentation of research results on leading research issues in wireless networking, wireless communications and mobile computing. The mission of the conference is to share novel basic research ideas as well as experimental applications in the wireless area in addition to identifying new directions for future research and development. ACM IWCMC 2009 gives researchers a unique opportunity to share their perspectives with others interested in the various aspects of wireless networking, wireless communication, information theory and mobile computing as well as other related topics. The conference consists of 11 symposia and 5 workshops that cover a broad range of research aspects. In addition, the program includes two outstanding keynote speakers: Prof. Gordon Stuber from Georgia Tech and Dr. Stefan Schmid of NEC Labs-Europe. There will also be two Tutorials given free of charge to all IWCMC attendees. We hope that the conference proceedings will serve as a valuable reference to researchers and developers in the area. This year, we have received more than 600 paper submissions from all over the world. All papers received rigorous peer reviews from our Technical Program Committee (TPC). After carefully examining all the received review reports, the TPC finally selected 285 high-quality papers for presentation at the conference and publication in the ACM IWCMC 2009 proceedings with a total of 43 technical sessions, organized in five parallel tracks. This year, the technical sessions reflect the continued and growing interests in a wide range of spectrum, including wireless communications and networks, crosslayer design and optimization, mobile computing, wireless sensor networks, network security, information theory and applications, etc.
