We warmly welcome you to WINSYS 2008 - the International Conference on Wireless Information Networks and Systems, which is held, this year, in Porto, Portugal. This conference reflects a continuing effort to increase the dissemination of recent research among professionals who work on the field of Wireless Information Systems. WINSYS is integrated as one of the modules of the ICETE joint conference. The participants in WINSYS 2008 can attend all sessions of the remaining 3 major conferences of ICETE. This is a golden opportunity for researchers as with the same registration fee, they can attend the technical presentations of the papers in the other 3 conferences. Moreover, this colocation allows an author to present his/her papers to more than one conference. Clearly, there is a lot of savings in terms of travel expenses, and accommodation cost, especially in these difficult economical days with skyrocketing oil prices that affected airfares and hotel rates, among others. The
major goals of WINSYS is to bring together researchers, engineers and practitioners interested in information and wireless network systems in order to share their research results and experience. WINSYS 2008 offers an exceptional forum for worldwide researchers and practitioners from academia, industry, business, and government to share their expertise results and research findings in all areas of wireless networks and systems. WINSYS 2008 program includes outstanding technical papers and distinguished keynote speeches. With these sessions, we expect to appeal to a global audience of the engineers, scientists, business practitioners and policy experts, interested in all areas of wireless networks and systems. ICETE has received 440 papers in total, with contributions from more than 40 different countries, from all continents, which demonstrates the success and global dimension of ICETE 2008. 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. In the end, 174 papers were selected for oral presentation and publication, corresponding to a 39% acceptance ratio. Of these only 77 were accepted as full papers (17% of submissions) and 97 as short papers. Additionally, 87 papers were accepted for poster presentation. These acceptance ratios demonstrate that ICETE 2008 strives to achieve a high quality standard which we will keep and enhance in order to ensure the success of next year conference, to be held in Milan/Italy. A short list of about thirty papers will be also selected to appear in a book that will be published by Springer. 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 was organized for the evening of Monday, July 28, 2008 in order to promote this kind of social networking. We would like to express our thanks, first of all, to the authors of the technical papers presented at the conference, whose work made possible to put together a high quality program. Next, we would like to thank all the members of the program committee and reviewers, who helped us with their expertise, dedication and time. We would also like to thank the invited speakers for their invaluable contribution, sharing their vision and knowledge. Naturally, a word of appreciation for the work of the secretariat and all other members of the organization, 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 you will find these proceedings interesting and a helpful reference in the future for all those who need to address the areas of wireless networks and systems.
