2014 2014 44th Annual IEEE/IFIP International Conference on Dependable Systems and Networks  
In this paper, we tackle these challenges in the context of quorum-based systems (e.g. Amazon Dynamo, Cassandra), an important class of cloud storage systems.  ...  We present models that optimize percentiles of response time under normal operation and under a data-center (DC) failure.  ...  Quorum-based datastores: Quorum protocols have been extensively used in the distributed systems community for managing replicated data [30] .  ...

An Evaluation Framework of Replication Protocols in Mobile Environment

Archana Sharma, Vineet Kansal
2013 International Journal of Database Management Systems  
Conventional data sharing systems are based on presumption that connections are reliable, and a faulty operation will be considered in case of losing a connection.  ...  For dynamically evolving environments to provide connectivity and reasonable use of shared resources adaptability is vital.  ...  The variation schemes of ROWA are proposed such as voting approach and quorum based approach [8] .  ...

Quantifying eventual consistency with PBS

Peter Bailis, Shivaram Venkataraman, Michael J. Franklin, Joseph M. Hellerstein, Ion Stoica
2014 Communications of the ACM  
We derive a closed-form solution for version-based staleness and model real-time staleness for a large class of quorum replicated, Dynamo-style stores.  ...  Data replication results in a fundamental trade-off between operation latency and consistency.  ...  quorum-style replication and we are not aware of any widely adopted data store that uses a substantially different quorum-based replication protocol.  ...

Advances in pervasive computing

J.H. Abawajy, J.H. Abawajy
2009 International Journal of Pervasive Computing and Communications  
Findings -Tools expected to support these advances are: resource location framework, data management (e.g. replica control) framework, communication paradigms, and smart interaction mechanisms.  ...  Pervasive computing systems operate in large-scale, highly heterogeneous domains with very unpredictable dynamics.  ...  In contrast, rather than being restricted to (or even requiring) pre-defined subject fields, subscribers in Content-based scheme have the added flexibility of selecting filtering criteria along multiple  ...

Quorum Systems towards an Asynchronous Communication in Cognitive Radio Networks

Sylwia Romaszko, Petri Mähönen
2012 Journal of Electrical and Computer Engineering  
Third, we also propose a novel distributed RDV protocol, MtQS-DSrdv, which is based on mirror torus QS and difference set concepts.  ...  This paper reviews quorum systems (QS) from the perspective of cognitive radio networks. Quorum systems were originally developed for and widely used in the scope of operating systems.  ...  Quorum systems are widely used in achieving the distributed mutual exclusion (DMX), for a consistent data replication [2] , solving agreement problems [3] , or dissemination of information.  ...

Transaction Management in a Mobile Data Access System [chapter]

K. SEGUN, A.R. HURSON, V. DESAI, A. SPINK, L.L. MILLER
2001 Annual Review of Scalable Computing  
The assignment of quorums lacks flexibility and is difficult to be optimized automatically. A new copy of the data cannot join the system until the quorums are rearranged.  ...  Dynamic replication can be used at this level to redistribute data to get closer to the access activities. Classical replication protocols are sufficient to handle this.  ...

A dynamic quorum is a technique whereby votes are evaluated and, subsequently, a cluster is reconfigured dynamically using an active member count or voters.  ...  While most of the current HAC solutions apply the dynamic reconfiguration procedure, there are also features that are specific to a dynamic quorum, such as running a cluster when only one node and a quorum  ...
