1 This year marks the l0 h anniversary of the IFIP International Workshop on Protocols for High-Speed Networks (PfHSN). It began in May 1989, on a hillside overlooking Lake Zurich in Switzerland, and arrives now in Salem Massachusetts 6,000 kilometers away and 10 years later, in its sixth incarnation, but still with a waterfront view (the Atlantic Ocean). In between, it has visited some picturesque views of other lakes and bays of the world: Palo Alto (1990 - San Francisco Bay), Stockholm (1993 - Baltic Sea), Vancouver (1994- the Strait of Georgia and the Pacific Ocean), and Sophia Antipolis I Nice (1996- the Mediterranean Sea). PfHSN is a workshop providing an international forum for the exchange of information on high-speed networks. It is a relatively small workshop, limited to 80 participants or less, to encourage lively discussion and the active participation of all attendees. A significant component of the workshop is interactive in nature, with a long history of significant time reserved for discussions. This was enhanced in 1996 by Christophe Diot and W allid Dabbous with the institution of Working Sessions chaired by an "animator," who is a distinguished researcher focusing on topical issues of the day. These sessions are an audience participation event, and are one of the things that makes PfHSN a true "working conference."

The first book to focus on the communications and networking aspects of UAVs, this unique resource provides the fundamental knowledge needed to pursue research in the field. The team of authors covers the foundational concepts of the topic, as well as offering a detailed insight into the state of the art in UAVs and UAV networks, discussing the regulations, policies, and procedures for deployment (including analysis of risks and rewards), along with demonstrations, test-beds, and practical real-world applications in areas such as wildlife detection and emergency communications. This is essential reading for graduate students, researchers, and professionals in communications and networking.

We welcome you to the proceedings of the Third International Workshop on Self-Organizing Systems (IWSOS 2008) hosted at the University of Vienna, Austria.IWSOSprovidesanannualforumtopresentanddiscussrecentresearch inself-organizationfocusedonnetworksandnetworkedsystems.Researchinse- organizingnetworkedsystemshasadvancedinrecentyears, buttheinvestigation of its potentials and limits still leaves challenging and appealing open research issues for this and subsequent IWSOS workshops. Complexandheterogeneousnetworksmakeself-organizationhighlydesirable. Bene?ts envisioned by self-organization are the inherent robustness and ada- ability to new dynamic tra?c, topology changes, and scaling of networks. In - dition to an increasingly complex Global Internet, a number of domain-speci?c subnetworks bene't from advances in self-organization, including wireless mesh networks, wireless sensor networks, and mobile ad-hoc networks, e.g., vehi- lar ad-hoc networks. Self-organization in networked systems is often inspired by other domains, such as nature (evolution theory, swarm intelligence), sociology (human cooperation), and economics (game theory). Aspects of controllability, engineering, testing, andmonitoringofself-organizingnetworksremainchalle- ing and are of particular interest to IWSOS. This year, we received 70 full paper and 24 short paper submissions from authors of 33 di?erent countries. This strong interest in the workshop is very encouraging for research in self-organizing systems and allowed us to provide a strong technical program. Based on the recommendations of the Technical Program Committee and external expert reviewers, we accepted 20 full papers from the full paper submissions and invited 9 as short papers. Of the 24 short paper submissions we accepted 4 for presentation for a total of 13 short pape

This book constitutes the refereed proceedings of the First International Workshop on Self-Organizing Systems, IWSOS 2006. The book offers 16 revised full papers and 6 revised short papers together with 2 invited talks and 3 poster papers. The papers are organized in topical sections on dynamics of structured and unstructured overlays, self-organization in peer-to-peer networks, self-organization in wireless environments, self-organization in distributed and grid computing, self-managing and autonomic computing, and more.

This book constitutes the refereed proceedings of the IFIP-TC6 4th International Working Conference on Active Networks, IWAN 2002, held in Zurich, Switzerland, in December 2002.The 20 revised full papers presented were carefully reviewed and selected from 53 submissions. Among the topics addressed are router architectures, reconfigurable systems, NodeOS, service deployment, active network services, active network queries, network management agents, active network performance, mobile communications, programmable networks, network execution environments, active network architecture, group communication, peer-to-peer networks, and interaction detection.
