On behalf of the Technical Program Committee, we welcome all of you to the IEEE Computing, Management and Telecommunications Conference (IEEE ComManTel 2013) in the beautiful REX Hotel, Ho Chi Minh City, Vietnam! We are indeed delighted that the conference aims to providing a premier forum for presentation of research results and experience reporting on the cutting edge research in the general areas of computing, telecommunications, management and their applications. This year, we received around 120 submissions from more than 20 countries. Each paper received at least three peer technical reviews, comprised of more than 120 TPC members from academia, government laboratories, and industries. After carefully examining all the received review reports, the IEEE ComManTel 2013 TPC finally selected only very high quality papers for presentation at the conference and publication in the IEEE ComManTel 2013 proceedings. The first day will start with a keynote speaker chosen from renowned world-class leaders in the area. On talk about the "Massive Data Centers for Future Cloud Computing Applications." Right after the Keynote, Prof. Markus Fiedler from the Blekinge Institute of Technology, Sweden, will deliver a free Tutorial to all attendees on "Quality Economy and Sustainability of Network Services." This year, the technical sessions reflect the growing interest in a wide range of spectrum, including wireless communications and networks, computing aspects, management and applications of these technologies in our daily lives. Outstanding papers will be selected and invited for Special Issues in well-known international journals. Our objective in the future is to increase the quality and therefore reduce the acceptance rate further to reach around 30%. In addition, we would like to increase the number of Tracks to cover other areas and introduce Workshops that of interest to meet the conference theme. A conference of this size cannot be organized without the hard work and dedication of many people. We want to thank all authors who submitted their manuscripts, as well as all the Track Chairs/Co-Chairs, TPC members, invited reviewers for all their contribution to the conference. Special gratitude goes to the IEEE Vietnam section and the IEEE headquarters for their technical sponsorship. We would also like to recognize our Co-Organizer and Financial Sponsor, Duy Tan University in Vietnam. Many thanks also goes to our financial sponsor: The National Foundation for Science and Technology Development (NAFOSTED) in Vietnam as well our Co-Organizer, REV/REH in Vietnam. We hope you all enjoy the city of Ho Chi Minh and the IEEE ComManTel 2013 technical program and find this conference a productive opportunity to explore, exchange ideas, make new friends, and best of all come back next year to contribute future ComManTel conferences.
