Understanding and Hardening Blockchain Network Security Against Denial of Service Attacks
… the security of a blockchain's communication network. A blockchain relies on a communication network to deliver transactions. Understanding and hardening the security of the communication network against Denial-of-Service (DoS) attacks are thus critical to the well-being of blockchain …

A Framework for Digital Investigation of Peer-to-Peer (P2P) Networks. An Investigation into the Security Challenges and Vulnerabilities of Peer-to-Peer Networks and the Design of a Standard Validated Digital Forensic Model for Network Investigations
Peer-to-Peer (P2P) Networks have been presenting many fascinating capabilities to the internet since their inception, which has made and is still gathering so much interest. As a result, it is being used in many domains, particularly in transferring a large amount of data, which is essential for …

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 …

GOssiping Optimization Framework (GOOF): A decentralized P2P architecture for function optimization
… on a fully decentralized, general purpose P2P environment, with no special or ad-hoc facility for executing optimization tasks. Relevant information is exchanged among nodes by means of epidemic protocols, exploiting the overlay network topology formed by peers. A key issue in such a …

Schema matching in a peer-to-peer database system
Peer-to-peer or P2P systems are applications that allow a network of peers to share resources in a scalable and efficient manner. My research is concerned with the use of P2P systems for sharing databases. To allow data mediation between peers' databases, schema mappings need to exist, which are …

Agent Extensions for Peer-to-Peer Networks.
Peer-to-Peer (P2P) networks have seen tremendous growth in development and usage in recent times. This attention has brought many developments as well as new challenges to these networks. We will show that agent extensions to P2P networks offer solutions to many problems faced by P2P networks. In …

Query Evaluation Techniques for Data Integration Systems
… virtual market places, to peer-to-peer (P2P) systems. Based on a new distributed evaluation technique, the so-called HyperQueries, we present a reference architecture for distributed virtual market places. These HyperQueries enable us to dynamically construct query evaluation plans by …

Reliable peer-to peer multicast streaming
P2P is increasingly gaining its popularity for streaming multimedia contents. The architecture of streaming has shifted from traditional client server architecture to P2P architecture. Although it is scalable and robust it faces its own challenges and problems such as churn. In tree topology …

Volatility-Aware Query Processing in Peer-to-Peer Systems
Peer-to-Peer (P2P) paradigm has been recognized as a disruptive technology that can aggregate enormous storage and processing resources for information sharing and distributed computing. This paradigm has received significant attention in both academic and industry. However, most of the effort has …

Trust management schemes for peer-to-peer networks
Peer-to-peer (P2P) networking enables users with similar interests to exchange, or obtain files. This network model has been proven popular to exchange music, pictures, or software applications. These files are saved, and most likely executed, at the downloading host. At the expense of this …

A NOVEL LINEAR DIOPHANTINE EQUATION-BAESD LOW DIAMETER STRUCTURED PEER-TO-PEER NETWORK
… 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 their …

Architectures and technologies for quality of service provisioning in next generation networks
A NGN is a telecommunication network that differs from classical dedicated networks because of its capability to provide voice, video, data and cellular services on the same infrastructure (Quadruple-Play). The ITU-T standardization body has defined the NGN architecture in three different and …

Content dissemination for static and dynamic mobile P2P groups
… protocols for static and dynamic peer-to-peer (P2P) groups. In the first part of the thesis we delve into the problem of inefficient content dissemination for static mobile device users due to cellular congestion. We propose the Sangam Framework which utilizes multiple radio interfaces and …

Trust Management for P2P application in Delay Tolerant Mobile Ad-hoc Networks. An Investigation into the development of a Trust Management Framework for Peer to Peer File Sharing Applications in Delay Tolerant Disconnected Mobile Ad-hoc Networks.
… Delay tolerant and disconnected Mobile Ad Hoc Networks (MANET) are a class of networks characterized by high end-to-end path latency and frequent end-to-end disconnections and are often termed as challenged networks. In these networks nodes are sparsely populated and without the existence of a …
