This book contains the refereed proceedings of the Fourth Annual Mediterranean Ad Hoc Networking Workshop, Med-Hoc-Net 2005. After Sardinia (Italy), Mahdia (Tunisia), Bodrum (Turkey), the workshop took place this year on the beautiful island, fle de Porquerolles (France). The Med-Hoc-Net 2005 event consolidates the success of the previous editions of the workshop series. It aims to serve as a platform for researchers from academia, research, laboratories and industry from all over the world to share their ideas, views, results and experiences in the field of ad hoc networking. This year, 73 papers were submitted. We accepted 39 papers as full papers and 10 papers as short papers. Each full paper consists in 10 pages in these proceedings and was presented orally at the workshop whereas each short paper consists in 5 pages in these proceedings and was presented as a poster at the workshop. The selected papers were grouped according to the following topics: Physical and MAC layers, Power Consumption, Quality of Service, Routing, Connectivity, Optimization and Testbeds, Multicast and Broadcast, Clustering, Sensor networks, Auto-organization and Adaptation, Security and Evolution and finally Analysis. The accepted papers came from all over the world, mainly from diverse countries in Europe, but also from USA, Brazil, Tunisia, China and Taiiwan. We thank all authors for submitting their papers to Med-Hoc-Net 2005. For each paper, we provided two reviews (sometimes three reviews).

International Federation for Information Processing

The IFIP series publishes state-of-the-art results in the sciences and technologies of information and communication. The scope of the series includes: foundations of computer science; software theory and practice; education; computer applications in technology; communication systems; systems modeling and optimization; information systems; computers and society; computer systems technology; security and protection in information processing systems; artificial intelligence; and human-computer interaction. Proceedings and post-proceedings of referred international conferences in computer science and interdisciplinary fields are featured. These results often precede journal publication and represent the most current research. The principal aim of the IFIP series is to encourage education and the dissemination and exchange of information about all aspects of computing.
