Efficient routing for peer-to-peer systems
… the problem of locating and accessing an item stored in a large and volatile peer-to-peer system, and presents new ways of organizing items and peers to make this operation fast and efficient. Current structured peer-to-peer routing schemes keep routing information about only a small number of …

ISP-Aided Neighbour Selection in Peer-to-Peer Systems
Peer-to-Peer (P2P) Systeme verursachen heutzutage mehr als die Hälfte des Internetverkehrs, und eine wachsende Anzahl von Applikationen, z.B. Bittorrent, eDonkey, Joost, Skype, GoogleTalk und P2P-TV nutzen die P2P-Methodik. P2P-Systeme errichten Overlays auf der Applikationsschicht, unabhängig von …

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 …

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. …

Conformance testing of peer-to-peer systems using message traffic analysis
Peer-to-Peer architectures are used by a large number of distributed systems; however, the challenges such as maintaining a reliable and stable peer-to-peer network can make such networks undesirable for distributed systems. Peer-to-peer architectures are designed to be executed on systems with …

Conformance preserving data dissemination for large-scale peer to peer systems
In today's applications where dealing with vast stream data becomes a norm rather than an exception, it is in urgent need to design data dissemination systems in large scale. We identify a new pattern of data dissemination based on conformance constraints where data accuracy can be traded for low …

Metanorms, Topologies, and Adaptive Punishment in Norm Emergence
Norms provide a means to regulate the behaviour of the members of a society, organisa¬tion or system. While much work has been done on various aspects of norms, normative systems and normative behaviour, this work has been limited in several respects. In particular, the problems of norm emergence …
