In this paper we present PEAS, a robust energy-conserving protocol that can build long-
lived, resilient sensor networks using a very large number of small sensors with short battery …

Generalized snapshot isolation extends snapshot isolation as used in Oracle and other
databases in a manner suitable for replicated databases. While (conventional) snapshot …

Classical approaches to performance prediction rely on two, typically antithetic, techniques:
Machine Learning (ML) and Analytical Modeling (AM). ML takes a black box approach …

The widespread use of clusters and Web farms has increased the importance of data
replication. In this article, we show how to implement consistent and scalable data …

At current date the problem of how to build distributed and replicated software transactional
memory (STM) to enhance both dependability and performance is still largely unexplored …

This book is the result of the seminar “A 30-Year Perspective on Replication,” which took
place at Monte Verita, Ascona, Switzerland, in November 2007. As suggested by the title, the …

In this paper, we present a performance comparison of database replication techniques
based on total order broadcast. While the performance of total order broadcast-based …

The problem of distributed consensus has played a major role in the development of
distributed data management systems. This includes the development of distributed atomic …

State machine replication (SMR) is a well-known technique able to provide fault-tolerance.
SMR consists of sequencing client requests and executing them against replicas in the …

Transaction logging and log ship** are standard techniques to provide recoverability and
high availability in data management systems. They entail an update to a local log file at …
