Building Scalable and Consistent Distributed Databases Under Conflicts
(University of Waterloo, 2018-04-12)Distributed databases, which rely on redundant and distributed storage across multiple servers, are able to provide mission-critical data management services at large scale. Parallelism is the key to the scalability of ... -
Computation Reduction for Angle of Arrival Estimation Based on Interferometer Principle
(University of Waterloo, 2017-09-28)Advancement in wireless technology and the oncoming of the Internet of Things (IoT) marked an incredible growth in the wireless connectivity, ultimately concluding to a major expansion in the mobile electronics industry. ... -
Designing an Incentive-compatible Reward Scheme for Algorand
(University of Waterloo, 2022-06-21)Founded in 2017, Algorand is the first carbon-negative blockchain protocol inspired by proof of stake. Algorand uses a Byzantine agreement protocol to add new blocks to the blockchain. The protocol can tolerate malicious ... -
Detectable Data Structures for Persistent Memory
(University of Waterloo, 2021-05-14)Persistent memory is a byte-addressable and durable storage medium that provides both performance benefits of main memory and durability of secondary storage. It is possible for a data structure to recover near-instantly ... -
EA-PHT-HPR: Designing Scalable Data Structures for Persistent Memory
(University of Waterloo, 2020-08-28)Volatile memory has dominated the realm of main memory on servers and computers for a long time. In 2019, Intel released to the public the Optane data center persistent memory modules (DCPMM). These devices offer the ... -
Energy Efficient Energy Analytics
(University of Waterloo, 2017-05-19)Smart meters allow for hourly data collection related to customer's power consumption. However this results in thousands of data points, which hides broader trends in power consumption and makes it difficult for energy ... -
A Scalable Recoverable Skip List for Persistent Memory on NUMA Machines
(University of Waterloo, 2021-10-20)Interest in recoverable, persistent-memory-resident (PMEM-resident) data structures is growing as availability of Intel Optane Data Center Persistent Memory increases. An interesting use case for in-memory, recoverable ... -
ShallowForest: Optimizing All-to-All Data Transmission in WANs
(University of Waterloo, 2019-05-23)All-to-all data transmission is a typical data transmission pattern in both consensus protocols and blockchain systems. Developing an optimization scheme that provides high throughput and low latency data transmission can ... -
Snapshotting Mechanisms for Persistent Memory-Mapped Files
(University of Waterloo, 2023-09-21)In this research, we explore ways to enhance the reliability of persistent memory systems. Using Montage (ICPP'21) as our reference model, we identify areas of potential improvement, especially concerning the risk of data ... -
Tuning and Predicting Consistency in Distributed Storage Systems
(University of Waterloo, 2017-09-27)Distributed storage systems are constrained by the finite speed of propagation of information. The CAP (which stands for consistency, availability, and partition tolerance) theorem states that in the presence of network ... -
Understanding Scalability Issues in Sharded Blockchains
(University of Waterloo, 2020-12-11)Since the release of Bitcoin in 2008, cryptocurrencies have attracted attention from academia, government, and enterprises. Blockchain, the backbone ledger in many cryptocurrencies, has shown its potential to be a data ...
