Deferred node-copying scheme for XQuery
"... Abstract. XQuery is generic, widely adopted language for querying and manipulating XML data. Many of currently available native XML databases are using XQuery as its primary query language. The XQuery specification requires each XML node to belong to exactly one XML tree. In case of the XML subtree ..."

In this paper, we present a new XML node copying scheme that defers the node data copy operation un-less necessary. We will show that this schemes significantly
Accessing Nearby Copies of Replicated Objects in a Distributed Environment

To ensure both fast access to the objects as well as efficient utilization of network resources, it is desirable that each access request be satisfied by a copy "clos ..."

Pastry: Scalable, distributed object location and routing for large-scale peer-to-peer systems
, 2001
"... This paper presents the design and evaluation of Pastry, a scalable, distributed object location and routing scheme for wide-area peer-to-peer applications. Pastry provides application-level routing and object location in a potentially very large overlay network of nodes connected via the Internet. ..."

. It can be used to support a wide range of peer-to-peer applications like global data storage, global data sharing, and naming. An insert operation in Pastry stores an object at a user-defined number of diverse nodes within the Pastry network. A lookup operation reliably retrieves a copy of the requested
Storage management and caching in PAST, a large-scale, persistent peer-to-peer storage utility
, 2001
"... This paper presents and evaluates the storage management and caching in PAST, a large-scale peer-to-peer persistent storage utility. PAST is based on a self-organizing, Internetbased overlay network of storage nodes that cooperatively route file queries, store multiple replicas of files, and cache a ..."

additional copies of popular files. In the PAST system, storage nodes and files are each assigned uniformly distributed identifiers, and replicas of a file are stored at nodes whose identifier matches most closely the file’s identifier. This statistical assignment of files to storage nodes approximately
The dangers of replication and a solution
- IN PROCEEDINGS OF THE 1996 ACM SIGMOD INTERNATIONAL CONFERENCE ON MANAGEMENT OF DATA
, 1996
"... Update anywhere-anytime-anyway transactional replication has unstable behavior as the workload scales up: a ten-fold increase in nodes and traflc gives a thousand fold increase in deadlocks or reconciliations. Master copy replication (primary copyj schemes reduce this problem. A simple analytic mode ..."

Routing in Ad-Hoc Networks Using Minimum Connected Dominating Sets
, 1997
"... this paper, we impose a virtual backbone structure on the ad-hoc network, in order to support unicast, multicast, and fault-tolerant routing within the ad-hoc network. This virtual backbone differs from the wired backbone of cellular networks in two key ways: (a) it may change as nodes move, and (b) ..."

Wherefore Art Thou R3579X? Anonymized Social Networks, Hidden Patterns, and Structural Steganography
, 2007
"... In a social network, nodes correspond to people or other social entities, and edges correspond to social links between them. In an effort to preserve privacy, the practice of anonymization replaces names with meaningless unique identifiers. We describe a family of attacks such that even from a singl ..."

Single-copy Routing in Intermittently Connected Mobile Networks

, 2004

Abstract — Intermittently connected mobile networks are wireless networks where most of the time there does not exist a complete path from source to destination, or such a path is highly unstable and may break soon after it has been discovered. In this context, conventional routing schemes would fai ..."

Iterated Register Coalescing
