It is our great pleasure to present the proceedings of the European Conference on Wireless Sensor Networks 2010 (EWSN 2010). As the field of wireless sensor networks matures, new design concepts, experim- tal and theoretical findings, and applications have continued to emerge at a rapid pace. As one of the leading international conferences in this area, EWSN has played a s- stantial role in the dissemination of innovative research ideas from researchers all over the globe. EWSN 2010 was organized by the University of Coimbra, Portugal, during February 17-19, 2010 and it was the seventh meeting in this series. Previous events were held in Berlin (Germany) in 2004, Istanbul (Turkey) in 2005, Zurich (Switz- land) in 2006, Delft (The Netherlands) in 2007, and Cork (Ireland) in 2009. A high-quality selection of papers made up EWSN 2010. Based on the reviews and the recommendations from the four live TPC discussions, we selected a total of 21 papers from 109 submissions (19.26% acceptance rate) for EWSN 2010. Topics of interest included hardware design and implementation, operating systems and so- ware, middleware and macroprogramming, communication and network protocols, information and signal processing, fundamental theoretical limits and algorithms, prototypes, field experiments, testbeds, novel applications, including urban sensing, security and fault-tolerance. Putting together EWSN 2010 was a team effort. We would like to thank the P- gram Committee members, the reviewers, our sponsors, all authors, and the Organ- ing Committee for their respective contributions.

This book constitutes the refereed proceedings of the 5th International Conference on Wired/Wireless Internet Communications, WWIC 2007, held in Coimbra, Portugal in May 2007.

The 32 revised full papers presented were carefully reviewed and selected from 257 submissions. The papers are organized in topical sessions on transport layer issues, handover and QoS, traffic engineering, audio/video over IP, IEEE 802.11 WLANs, sensor networks, protocols for ad-hoc and mesh networks, as well as OFDM systems.

This book constitutes the refereed proceedings of the Joint International Workshops on Interactive Distributed Multimedia Systems and Protocols for Multimedia Systems, IDMS/PROMS 2002, held in Coimbra, Portugal in November 2002.The 30 revised full papers presented were carefully reviewed and selected from 112 submissions. The papers are organized in topical sections on performance of protocols and applications, mobile multimedia systems, standards and related issues, quality of service, video systems and applications, resource management, and multimedia support.

This book constitutes the refereed proceedings of the Second International Workshop on Quality of Future Internet Services, QofIS 2001, organized by the European COST Action 263, in Coimbra, Portugal, in September 2001.The 22 revised full papers presented were carefully selected during a competitive reviewing process from a total of 87 submissions. The book offers topical sections on quality of service for multimedia communication, admission control, QoS routing, differentiated services networks, QoS monitoring and mapping, and traffic engineering.
