TL;DR: The authors address some of the questions, by proposing an adaptive replication scheme for mobile data, which is dependent not only on the distance between them but also on the cost of search necessary to determine the exact value of location.

Abstract: Mobility of users and services and its impact on data replication and migration will be one of the main technical problems to be resolved. In fact, the authors view mobility as probably the most challenging new issue facing distributed systems of the future. The distinct new element which mobility brings into the issues of data replication is system's uncertainty about its own state (meaning primarily location). Thus the cost of communication between two mobile users is dependent not only on the distance between them but also on the cost of search necessary to determine the exact value of location. The authors address some of the questions, by proposing an adaptive replication scheme for mobile data. >

System for synchronizing data between computers using a before-image of data
Jonathan A. Bauer,Andrew Bodge,Steven Huberman +2 more
- 09 Oct 1996
TL;DR: In this paper, a database synchronizer is used to synchronize the data in a central database for a particular client with the data on that client's intermittently-connected computer, where updates performed by either client or server are propagated to the other side when a connection is established and eventually from the server to other clients in the system.

A quadtree-based dynamic attribute indexing method
TL;DR: A variant of the quadtree structure is adapted to solve the problem of indexing dynamic attributes based on the key idea of using a linear function of time for each dynamic attribute that allows us to predict its value in the future.

TL;DR: In this article, a database synchronizer is used to synchronize the data in a central database for a particular client with the data on that client's intermittently-connected computer, where updates performed by either client or server are propagated to the other side when a connection is established and eventually from the server to other clients in the system.

Checkpointing distributed applications on mobile computers
Arup Acharya,B. R. Badrinath +1 more
- 28 Sep 1994
TL;DR: This paper presents a checkpointing algorithm for MHs that satisfies the constraints and identifies the problems in recording a consistent global state of mobile distributed applications.

A framework for delivering multicast message in networks with mobile hosts
Arup Acharya,B. R. Badrinath +1 more
TL;DR: The problems associated with delivering multicast meassages to mobile hosts are looked at and “multicast groups” of mobile hosts wherein each multicast group is associated with a “host view”, a set of MSSs representing the aggregate location information of the group.

TL;DR: By means of a design example, it is shown how these techniques can work together to meet some of the demands of third-generation systems.

Distributed algorithms for dynamic replication of data
Ouri Wolfson,Sushil Jajodia +1 more
- 01 Jul 1992
TL;DR: Two distributed algorithms for dynamic replication of a data-item in communication networks are presented, each of which continuously moves the replication scheme towards an optimal one, where optimality is defined with respect to different objective functions.

Service interface and replica management algorithm for mobile file system clients
C.D. Tait,D. Duchamp +1 more
- 01 Dec 1991
TL;DR: The authors argue that existing approaches to file replica management would not cope well with the likely behavior of mobile clients, and they present a lazy server-based update operation that facilitates fast, scalable, and highly fault tolerant implementations of both read and write operations in the usual case.
Data caching tradeoffs in client-server DBMS architectures
Michael J. Carey,Michael J. Franklin,Miron Livny,Eugene J. Shekita +3 more
- 01 Apr 1991
TL;DR: This paper presents a range of lock-based cache consistency algorithms that arise by viewing cache consistency as aiant of the well-understood problem of replicated data management, and uses a detailed simulation model to study the performance of these algorithm over a wide range of workloads end system resource configurations.
Data caching issues in an information retrieval system
TL;DR: Using a user's local storage capabilities to cache data at the user's site would improve the response time of user queries albeit at the cost ofurring the overhead required in maintaining multiple copies.
