Résumé :
This volume presents the proceedings of the Seventh International Workshop on Distributed Algorithms (WDAG 93), held in Lausanne, Switzerland, September 1993. It contains 22 papers selected from 72 submissions. The selection was based on originality, quality, and relevance to the field of distributed computing: 6 papers are from Europe, 13 from North America, and 3 from the Middle East. The papers discuss topics from all areas of distributed computing and their applications, including distributed algorithms for control and communication, fault-tolerant distributed algorithms, network protocols, algorithms for managing replicated data, protocols for real-time distributed systems, issues of asynchrony, synchrony and real-time, mechanisms for security in distributed systems, techniques for the design and analysis of distributed algorithms, distributed database techniques, distributed combinatorial and optimization algorithms, and distributed graph algorithms.
