This book constitutes the refereed proceedings of the 14th International Colloquium on Structural Information and Communication Complexity, SIROCCO 2007, held in Castiglioncello, Italy in June 2007. The 23 revised full papers and four invited talks cover graph exploration, fault tolerance, distributed algorithms and data structures, location problems, wireless networks, fault tolerance, as well as parallel computing and selfish routing.

SIROCCO 2005 was the twelfth in this series, held in Mont Saint-Michel, France, May 24 26, 2005.

This book constitutes the refereed proceedings of the 13th International Colloquium on Structural Information and Communication Complexity, SIROCCO 2006, held in Chester, UK, July 2006. The book presents 24 revised full papers together with three invited talks, on topics in distributed and parallel computing, information dissemination, communication complexity, interconnection networks, high speed networks, wireless and sensor networks, mobile computing, optical computing, autonomous robots, and related areas.

This book constitutes the refereed proceedings of the 15th International Colloquium on Structural Information and Communication Complexity, SIROCCO 2008, held in Villars-sur-Ollon, Switzerland, in June 2008. The 22 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 52 submissions. The papers cover topics such as distributed algorithms, compact data structures, information dissemination, informative labeling schemes, combinatorial optimization, and others, with potential applications to large scale distributed systems including global computing platforms, peer-to-peer systems and applications, social networks, wireless networks, and network protocols (such as routing, broadcasting, localization).

This book constitutes the refereed proceedings of the 18th International Colloquium on Structural Information and Communication Complexity, SIROCCO 2011, held in Gdańsk, Poland, in June 2011. The 24 revised full papers presented together with 1 survey lecture and 2 invited talks were carefully reviewed and selected from 57 submissions. The papers are organized in topical section on fault tolerance, routing, mobile agents, mobile robots, probabilistic methods, distributed algorithms on graphs, and ad-hoc networks.

This book constitutes the thoroughly refereed post-conference proceedings of the 22nd International Colloquium on Structural Information and Communication Complexity, SIROCCO 2015, held in Montserrat, Spain, in July 2015. The 30 full papers presented together with 2 invited papers were carefully reviewed and selected from 78 submissions. The papers focus on the study of the interplay between communication and knowledge in multi-processor systems from both the qualitative and quantitative viewpoints.

This book constitutes the refereed proceedings of the 21st International Colloquium on Structural Information and Communication Complexity, SIROCCO 2014, held in Takayama, Japan, in July 2014.
