Foreword

ICE-B 2011 - the International Conference on E-business, which was held in Seville, Spain, hosted by the ETSII ????????? University of Seville. ICE-B 2011 is integrated in the ICETE (International Conference on e-Business and Telecom- munications) 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. we have included distinguished keynote lectures, papers, and posters to present the widest possible view on these technical areas. With its five tracks, we expect to appeal to a global audience of the engineers, scientists, business practitioners and policy experts, interested in R&D on Telecommunication Systems and Services: Applications; Enterprise Engineering; Mobility Collaboration & e-Services; and Technology Platforms. ICETE 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.
