Plutus : measuring message gossiping in P2P networks and providing incentives in cryptocurrencies
In this thesis, we present Plutus, an efficient and game-theoretically proven incentive mechanism for Algorand, a proof-of-stake cryptocurrency. In order to operate, Algorand requires users to constantly propagate messages but has no mechanism to incentivize users to do so. Plutus solves this …

Efficient cross-layer routing and congestion control architectures for distributed systems
… such as the Internet, datacenter and hybrid P2P networks share a common known challenge of finding an optimal path to transfer content from a source to a destination and the optimal rate at which content is transmitted. In general networks such as the Internet, per user, there is usually one …

Using current uptime to improve failure detection in peer-to-peer networks
Peer-to-Peer (P2P) networks share computer resources or services through the exchange of information between participating nodes. These nodes form a virtual network overlay by creating a number of connections with one another. Due to the transient nature of nodes within these systems any connection …

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 …

Peer-to-peer systems for simple and flexible information sharing
Peer to peer computing (P2P) is an architecture that enables applications to access shared resources, with peers having similar capabilities and responsibilities. The ubiquity of P2P computing and its increasing adoption for a decentralized data sharing mechanism have fueled my research interests. …

Measuring Ethereum's peer-to-peer network
… 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 Mainnet. We examine overall composition of the DEVp2p network. We analyze our peer connections on the …

Evolutionary methods for self-organizing cooperation in peer-to-peer networks
… final users and researchers for its features. P2P networks shift from the classic client-server approach to a high level of decentralization where there is no central control and all the nodes should be able not only to require services, but to provide them to other peers as well. While on one …

Self-Organizing Mechanisms for Task Allocation in a Knowledge-Based Economy
… science and in particular from Peer-to-Peer Networks (P2P) to organization theories. We think that the P2P paradigm well fits with organization problems related to all those situation in which a central authority is not possible. We believe that P2P Networks show a number of characteristics …

A physically-aware architecture for self-organizing peer-to-peer overlay networks
Over the last few years Peer-to-Peer (P2P) systems have emerged as highly attractive systems supporting many useful large-scale applications and services. They allow the exploitation of enormous untapped resources (such as idle processing cycles, storage, and bandwidth) available at …

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 …

Practical, scalable algorithms for Byzantine agreement
… a serious problem especially with peer-to-peer (p2p) networks which may have sizes of more than a million nodes. An important problem in designing reliable algorithms is Byzantine agreement. For reasons of scalability, message complexity is a critical resource for this problem. Unfortunately, …

Characterizing and leveraging people movement for content distribution in mobile Peer-to-Peer networks
… of content distribution in mobile Peer-to-Peer (P2P) networks. Particularly, we study two typical classes of people movement including the Schelling behavior and repetitive behavior. The Schelling behavior exists in real-world scenarios where co-located people collaboratively share mutual content …

Challenges for copyright holders on the Internet: a Turkish case study
… using the Internet. In the 1990s, Peer-to-Peer (P2P) file sharing networks exploited this new technology. Using file sharing networks, users started to download songs and movies without paying for them. As a result, the music and movie industry suffered great financial losses. While courts are …

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 …

Making Coding Practical: From Servers to Smartphones
… fundamental insight of use of coding in computer networks is that information to be transmitted from the source in a session can be inferred, or decoded, by the intended receivers, and does not have to be transmitted verbatim. Several coding techniques have gained popularity over the recent years. …
