2. 1. Virtual Full Replication for Scalable Distributed Real-Time Databases

   Author : Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik;

   Abstract : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

4. 2. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

   Author : Sanny Syberfeldt; Sten Andler; Jörgen Hansson; Sang H. Son; Alejandro Buchmann; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Computer science; Datalogi; Teknik;

   Abstract : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. READ MORE

5. 3. Scalable Data Management for Internet of Things

   Author : Khalid Mahmood; Tore Risch; Kjell Orsborn; Georgios J Fakas; Erik Zeitler; Vera Goebel; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NoSQL; IoT; Smart Computing; MongoDB; IIoT; Data Streams; Edge Computing; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

   Abstract : Internet of Things (IoT) often involve considerable numbers of sensors that produce large volumes of data. In this context, efficient management of data could potentially enable automatic decision making based on analytics of sensors on equipment. READ MORE

6. 4. Resource Management in Computing Systems

   Author : Payam Amani; Bredbandskommunikation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Resource management is an essential building block of any modern computer and communication network. In this thesis, the results of our research in the following two tracks are summarized in four papers. The first track includes three papers and covers modeling, prediction and control for multi-tier computing systems. READ MORE

7. 5. Scaling Distributed Hierarchical File Systems Using NewSQL Databases

   Author : Salman Niazi; Jim Dowling; Seif Haridi; Seif Haridi; Rui Oliveira; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. READ MORE
