Measuring Ethereum's peer-to-peer network
… in value, we still have very limited Ethereum network visibility. In this thesis, we analyze the Ethereum network from two vantage points: the DEVp2p network and the Ethereum Mainnet. The DEVp2p peer-to- peer (P2P) network was developed specifically for and ultimately underlies the Ethereum …

Peer-to-peer network modeling for adversarial proactive cyber defenses
This thesis implements a novel peer-to-peer network simulator that integrates co-evolutionary algorithms in order to model adversarial attack and defense dynamics in networks. Modeling this behavior is desirable as it allows for network designers to better develop network defense strategies against …

A service discovery framework for a peer-to-peer network
As mobile networks become ubiquitous, and devices like PDAs and cell phones become commonplace, today's traditional computing paradigms are no longer relevant. Instead, we now live in a world where computing power is pervasive, and the means to access that power is as simple as the click of a …

Arpeggio : metadata indexing in a structured peer-to-peer network
Peer-to-peer networks require an efficient means for performing searches for files by metadata keywords. Unfortunately, current methods usually sacrifice either scalability or recall. Arpeggio is a peer-to-peer file-sharing network that uses the Chord lookup primitive as a basis for constructing a …

Implementation Of A Raptorq-Based Protocol For Peer To Peer Network
… protocol. The RaptorQP2P protocol is a novel peer-to-peer protocol based on RaptorQ forward error correction. This protocol facilitates delivery of a single file to a large number of peers. It applies two levels of RaptorQ encoding to the source file before packet transmission. Download …

Analysis of Bitcoin as a peer-to-peer network for international payments
… infrastructure that runs the funds transfer network belongs to the pre-Internet era. As a result, international payments are expensive, slow, cumbersome, and not as secure as they could be. This thesis argues that the cryptocurrency Bitcoin is the answer to the problems facing millions of …

A NOVEL LINEAR DIOPHANTINE EQUATION-BAESD LOW DIAMETER STRUCTURED PEER-TO-PEER NETWORK
… a scalable, hierarchical interest-based overlay Peer-to-Peer (P2P) system. We have used Linear Diophantine Equation (LDE) as the mathematical base to realize the architecture. Note that all existing structured approaches use Distributed Hash Tables (DHT) and Secure Hash Algorithm (SHA) to realize …

An investigation into expanding the capabilities of peer-to-peer networks: combining centralized network infrastructure into decentralized peer-to-peer network topology
… signalling for session management over wireless networks. It’s the basis of a wide range of IP multimedia services. SIP relies on centralized servers according to its standard specifications and current usage. However, server based approaches are typically non-scalable as they may involve a large …

Producer Preferences for Alternative Irrigation Practices in the Arkansas Delta
… a bivariate sample selection model to address peer network effects on participation in and/or intensity of use of land being irrigated by alternative irrigation practices in the state of Arkansas. As groundwater in the state becomes more limited, the use of scientific scheduling, flowmeters, …

Expanding the Impact of Peer Networks: Pathways to Turning Points
… highlight the importance of both adolescent peers and prosocial life events in explanations of continuity and change in deviant behavior. Thus far, research has evaluated the pathway to desistance by focusing on what happens to one's trajectory after experiencing prosocial adult activities, …

Invisible Ink : blockchain for data privacy
… developed by the author and two collaborators, a peer-to- peer network that uses blockchain technology and off-blockchain storage to securely distribute sensitive data in a decentralized manner using a custom blockchain protocol. Our two main contributions are: 1. developing this platform and 2. …

Decentralized infrastructure for file storage
How might we incentivize a peer-to-peer network to store users' files? The purpose of this research is to combine ideas from existing peer-to-peer file sharing systems, blockchain technology and Proofs-of-Storage to create an incentivized decentralized storage network, where every participant can …

Simulating Network Structure, Layering Multi-layer Network System and Developing Network Block Configuration Model to Understand and Improve Energy Conservation in Residential Buildings
… consumption information among residents in a peer network. However, most of this research relies on experimental tests and does not theorize concepts related to peer network energy efficiency systematically. My dissertation addresses this research gap on two levels. First, I examined if and …
