Distributed Algorithms -

Résumé :
This volume presents the proceedings of the Sixth Workshop on Distributed Algorithms (WDAG 92), held in Haifa, Israel, November 2-4, 1992. WDAG provides a forum for researchers and other parties interested in distributedalgorithms and their applications. The aim is to present recent research results, explore directions for future research, and identify common fundamental techniques that serve as building blocks in many distributed algorithms. Papers in the volume describe original results in all areas of distributed algorithms and their applications, including distributed graph algorithms, distributed combinatorial algorithms, design of network protocols, routing and flow control, communication complexity, fault-tolerant distributed algorithms, distributed data structures, distributed database techniques, replica control protocols, distributed optimization algorithms, mechanisms for safety and security in distributed systems, and protocols for real-time distributed systems.
