This conference reflects a continuing effort to increase the dissemination of recent research results among professionals who work in the areas of e-business and tele- communications. ICETE is a joint international conference integrating four major areas of knowledge that are divided into four corresponding conferences: ICE-B (In- ternational Conf. on e-Business), SECRYPT (International Conf. on Security and Cryptography), SIGMAP (Int’l Conf. on Signal Processing and Multimedia) and WINSYS (International Conf. on Wireless Information Systems). The program of this joint conference included several outstanding keynote lectures presented by internationally renowned distinguished researchers who are experts in the various ICETE areas. Their keynote speeches have contributed to heightening the overall quality of the program and significance of the theme of the conference. The conference topic areas define a broad spectrum in the key areas of e-business and telecommunications. This wide-view reporting made ICETE appealing to a global audi- ence of engineers, scientists, business practitioners and policy experts. The papers ac- cepted and presented at the conference demonstrated a number of new and innovative solutions for e-business and telecommunication networks and systems, showing that the technical problems in these closely related fields are challenging and worthwhile ap- proaching an interdisciplinary perspective such as that promoted by ICETE. ICETE 2008 received 440 papers in total, with contributions from more than 40 different countries, in all continents, which really shows the success and global dimen- sion of the conference. To evaluate each submission, a double-blind paper evaluation method was used; each paper was reviewed by at least two experts from the Interna- tional Program Committee, and most papers received three reviews or even more. In the end, 174 papers were selected for oral presentation and publication, corresponding to a 39% acceptance rate. Of these only 77 were accepted as full papers (17% of sub- missions) and 97 as short papers. Additionally, 87 papers were accepted for poster presentation. We hope that you will find this collection of the best ICETE 2008 papers an excel- lent source of inspiration as well as a helpful reference for research in the aforemen- tioned areas.
