Resource Discovery Using Z39.50: Promise and Reality

Resource Discovery Using Z39.50: Promise and Reality

Date: November 2000
Creator: Moen, William E.
Description: This paper discusses the Z39.50 protocol. The ANSI/NISO Z39.50 protocol for information retrieval addresses the complex challenges of intersystem communication. Original uses envisioned for the protocol look very little like current implementations and uses. In the 1980s, users on one library catalog system would search and retrieve bibliographic records on a remote system. By the late 1990s, there was a need for discovering networked resources and integrating access to them. Yet, the Z39.50 protocol has addressed both these scenarios. This paper provides a portrayal of Z39.50 that explains its flexibility in response to a variety of information retrieval requirements in the networked environment.

Organization of Long-Term Interstellar Distributed Digital Preservation Networks

Organization of Long-Term Interstellar Distributed Digital Preservation Networks

Date: October 1, 2011
Creator: Halbert, Martin
Description: This presentation discusses the organization of long-term interstellar distributed digital preservation networks. Long term (centuries) management of large growing public bodies of information is both more and less understood. This presentation discusses what we can learn from current efforts to develop long term strategies for digital preservation.

Energy-Aware Time Synchronization in Wireless Sensor Networks

Energy-Aware Time Synchronization in Wireless Sensor Networks

Date: December 2006
Creator: Saravanos, Yanos
Description: I present a time synchronization algorithm for wireless sensor networks that aims to conserve sensor battery power. The proposed method creates a hierarchical tree by flooding the sensor network from a designated source point. It then uses a hybrid algorithm derived from the timing-sync protocol for sensor networks (TSPN) and the reference broadcast synchronization method (RBS) to periodically synchronize sensor clocks by minimizing energy consumption. In multi-hop ad-hoc networks, a depleted sensor will drop information from all other sensors that route data through it, decreasing the physical area being monitored by the network. The proposed method uses several techniques and thresholds to maintain network connectivity. A new root sensor is chosen when the current one's battery power decreases to a designated value. I implement this new synchronization technique using Matlab and show that it can provide significant power savings over both TPSN and RBS.

A Guide to Distributed Digital Preservation

A Guide to Distributed Digital Preservation

Date: 2010
Creator: MetaArchive Cooperative
Description: This text is a collection of essays that gives an overview of the reasons for considering distributed digital preservation (a system which maintains copies of digital objects in multiple geographic locations) as well as considerations for implementing this kind of digital preservation. According to the back cover, "Readers may use this guide to gain both a philosophical and practical understanding of the emerging field of distributed digital preservation, including how to establish or join a network."
