We warmly welcome you to DCNET 2011 - the International Conference on Data Communication Networking and OPTICS 2011 - the International Conference on Optical Communication Systems, which are held, this year, in Seville, Spain, hosted by the ETSII – University of Seville. DCNET 2011 and OPTICS 2011 conferences are integrated in the ICETE (International Conference on e-Business and Telecommunications) joint conference, which puts together six complementary conferences, namely DCNET, ICE-B, OPTICS, SECRYPT, SIGMAP and WINSYS, covering a broad range of related fields, including data communication networking, e-business, optical communication systems, security and cryptography, signal processing and multimedia applications, and wireless networks and information systems. Sponsored by INSTICC (the Institute for Systems and Technologies of Information, Control and Communication), the conference is technically co-sponsored by IEEE Systems Council, and held in cooperation with IACR (the
International Association for Cryptologic Research), ACM SIGSAC (Special Interest Group on Security, Audit and Control), ACM SIGMM (Special Interest Group on Multimedia), ACM SIGMIS (Special Interest Group on Management Information Systems), IEICE (the Japanese Institute of Electronics, Information and Communication Engineers), ATI (Asociación de Técnicos de Informática, CEPIS (Council of European Professional Informatics Societies), Fidetia (Fundación para la Investigación y el Desarrollo de las Tecnologías de la Información en Andalucía) and INES(Iniciativa Española de Software y Servicios). In the ICETE’s program, we have included distinguished keynote lectures, research papers, and posters to present the widest possible view on these technical areas. With its six tracks, we expect it to appeal to a global audience of the engineers, scientists, business practitioners and policy experts, interested in R&D on Telecommunication Systems and Services. All tracks focus on research related to real world applications and rely on contributions not only from academia, but also from industry, business and government with different solutions for end-user applications and enabling technologies, in a diversity of communication environments. The accepted papers demonstrate a number of new and innovative solutions and the vitality of these research areas. ICETE has received 409 papers in total, with contributions from 59 different countries, in all continents, which demonstrates the success and global dimension of ICETE 2011. To evaluate each submission, a double blind paper evaluation method was used: each paper was reviewed by at least two experts from the International Program Committee, in a double-blind review process, and most papers had 3 reviews or more. The selection process followed strict criteria in all tracks so only 52 papers were accepted and orally presented at ICETE as full papers (12.7% of submissions) and 66 as short papers (16.1% of submissions). Additionally, 52 papers were accepted for poster presentation. With these acceptance ratios, ICETE 2011 continues the tradition of previous ICETE conferences, a quality conference with high calibre. The best papers of the conference will be invited to appear in a post-conference book that will be published by Springer. We would like to emphasize that ICETE 2011 includes several outstanding keynote lectures, which are relevant to today’s lines of research, development and technical innovation. These talks are presented by distinguished researchers who are internationally renowned experts in one or more of the ICETE areas, and who help enhancing the overall quality of our Conference with their outstanding contributions. A successful conference involves more than paper presentations; it is also a meeting place, where ideas about new research projects and other ventures are discussed and debated. Therefore, a social event including a conference diner/banquet has been planned for the evening of July 19 in order to promote this kind of social networking. We would like to express our thanks to all colleagues involved in supporting this conference. First of all, we thank all authors including those whose papers were not included in the program. We also would like to thank all members of the international program committee and reviewers, who provided an invaluable help with their expertise, dedication and time. We would also like to thank the invited speakers for their invaluable contribution, in sharing their vision and knowledge. Naturally, a word of appreciation for the outstanding work of the ICETE 2011 Secretariat and all other members of the organizing committee and sponsors, whose diligence in dealing with all organizational issues were essential and required a collaborative effort of a dedicated and highly capable team. We hope that the papers accepted and included in the proceedings may be a helpful reference in future works for all those who need to address topics in data communication networking and optical communication systems as well as other ICETE knowledge areas. Enjoy the program and your stay in Seville.
