Multiversion concurrency control for large-scale service directories
Third European Conference on Web Services (ECOWS'05), 2005 In this paper we describe the implementation of multiversion concurrency control on the generalized search tree (GiST), an index structure introduced by Hellerstein. For large-scale service directories, the need arises for a data storage system capable of handling substantial amounts of multidimensional data efficiently, as well as being able to ...

Distributed Multiversion Optimistic Concurrency Control for Mobile Real-Time Database Systems
2007 International Conference on Wireless Communications, Networking and Mobile Computing, 2007 In this paper, DMVOCC-MDA-2PLV protocol is proposed for processing mobile distributed real-time transaction in mobile broadcast environments. The new protocol can eliminate conflicts between mobile read-only and mobile update transactions, and resolve data conflicts flexibly using multiversion dynamic adjustment of serialization order to avoid ...

Proceedings of the 1997 International Database Engineering and Applications Symposium (Cat. No.97TB100166), 2002 Concurrency control protocols based on multiversions have been used in some commercial transaction processing systems in order to provide the serializable executions of transactions. In the existing protocols, transactions are allowed to read only the most recent version of each data item in order to ensure the correct execution of transactions ...

A real-time concurrency control algorithm: Use of multiversion and precedence relationships
Journal of Systems Architecture, 1997 Abstract This paper proposes a multiversion concurrency control algorithm for real-time databases. Based on a priority cognitive algorithm commonly used in real-time processing, the algorithm resolves data conflicts among conflicting transactions in favor of the urgent transactions, i.e., those with higher priority.

MPX: A Multiversion Concurrency Control Protocol for XML Documents
, 2005 With the rapid popularity of XML, especially in web-base applications, concurrency control of XML documents becomes an important issue. In this paper, we present MPX, a multiversion concurrency control protocol for XML documents, which is designed for synchronizing concurrent queries and modifications of XML documents stored in a native XML databases ...

Wireless Networks, 2016 In mobile ad hoc network, the existing replication technique and multiversion scheme increase the cost of overhead. In addition, there is possibility of mobility- and energy-related issues. In order to overcome these issues, in this paper, we propose a hierarchical replication and multiversion concurrency control model for mobile database systems.

RF-MVTC: an efficient risk-free multiversion concurrency control algorithm
Concurrency and Computation: Practice and Experience, 2004 AbstractIn this paper, we focus on the temporary return of data values that are incorrect for given transactional semantics that could have catastrophic effects similar to those in parallel and discrete event simulation systems. In many applications using online transactions processing environments, for instance, it is best to delay the response to a ...

, 1986 A new multiversion concurrency control scheme for a distributed database system is proposed in this paper. Each data object in our database model has two copies allocated in different sites in the system. Unlike the usual distributed database systems with redundant copies, these two copies are not concurrently updated, but only one is updated for a ...

Multiversion Concurrency Control on Intermittent Systems
2019 IEEE/ACM International Conference on Computer-Aided Design (ICCAD), 2019Concurrency control allows multiple tasks that share data objects to be concurrently executed in a serializable order, thus significantly improving computation progress. However, to accumulate forward progress on energy-harvesting intermittent systems while achieving data consistency across power cycles, existing approaches based on the checkpointing ...
