Decentralized Network Algorithms
In the second part of this dissertation we investigate the problem of disseminating a large file to a large network of users. The file is divided into pieces, and different pieces are initially uploaded to different users. The users then exchange pieces to complete their individual collections. In …

Decentralized Data Markets
… data sharing. In this thesis, I describe a decentralized model of data markets to overcome privacy concerns in siloed, data-limited domains such as healthcare. I propose two federated techniques to automatically select a subset of data sellers and datapoints for a buyer given some sample …

Decentralized infrastructure for file storage
… and Proofs-of-Storage to create an incentivized decentralized storage network, where every participant can earn a reward for storing and serving files or pay the network to store or retrieve their own. More broadly, in this thesis we present the elementary components for building decentralized …

Secure Computation in Decentralized Systems
Decentralized systems like Bitcoin and Ethereum are real-world examples of secure distributed systems deployed at scale. Over the past decade, these systems and others have proven to provide a trust-minimized solution for computing. They ensure the correct execution of code (correctness), maintain …

Decentralized Synergetic Control of Power Systems
The objective of this dissertation is to design decentralized controllers to enhance the transient stability of power systems. Due to the nonlinearities and complexities of the system, nonlinear control design techniques are required to improve its dynamic performance. In this dissertation a …

Decentralized object finding using forwarding address
… services it is desirable that object finding be decentralized and allow any group of processors to proceed independently and autonomously. Given a model of a decentralized system in which objects are analogous to moveable physical objects and in which access rights are carried only by proper …

DECENTRALIZED CONTROL OF DISTRIBUTED PROCESSING SYSTEMS
… thesis presents a methodology for implementing decentralized scheduling for distributed systems. The environment in which the controlling entities make decisions is stochastic and can be described as uncertain since each entity may have a different view of the system state. As a consequence, …

DECENTRALIZED CONTROLLERS FOR INTERCONNECTED POWER SYSTEMS
This thesis presents the results of studies carried out into problems associated with the provision of auxiliary damping of electromechanical oscillations in a multi-machine electrical power system. A particular real power system comprised of five generating plants and an infinite bus was …

Decentralized Control and Multicriterion Decision-Making
… from the presence of conflicting goals among decentralized controllers. Of primary interest is the role that the Stackelberg strategy can play in the decentralized control problem.

Decentralized thermal control of building systems
… of partitioning them into clusters for decentralized control, to balance underlying performance and robustness requirements. Measures of deviation in performance and robustness between centralized and decentralized architectures in the Model Predictive Control framework are derived. …

Heterogeneous machine learning with decentralized data
… explores heterogeneous machine learning with decentralized data, where multiple clients with distinct data distributions jointly train or adapt machine learning models under the coordination of a central server. Throughout the process, clients’ private data never leave their local devices. …

Towards Bridging and Governing Decentralized Communities
… others. Fortunately, emerging strategies in decentralized protocols and networks have begun to change this dynamic. Decentralized systems designed for local governance can empower communities to create more nuanced and context-sensitive rules. However, these approaches remain largely …

DRACL (Decentralized resource access control list)
DRACL is a privacy-preserving, scalable, secure, and developer and user friendly federated access control system. It allows producers to manage, through a single authentication provider, which consumers can access what content across all content hosts that support the DRACL protocol. It preserves …

Decentralized utilization incentives in electronic cash
… to create resource utilization incentives via decentralized mechanisms. Decentralized mechanisms may be economically sustainable without centralized and potentially coercive forces. We propose Hourglass, a novel electronic cash design that provides a decentralized mechanism to encourage …

Local differential privacy in decentralized optimization
… local differential privacy (LDP) in interactive decentralized optimization. Comparing to central differential privacy (DP), where a centralized curator maintains the dataset, LDP is a stronger notion yet with industrial adoption, which allows data of an individual to be privatized before sharing. …
