Most peer-to-peer (P2P) systems build their own overlay networks for implementing peer selection strategies without taking into account the locality on the underlay network. As a result, a large quantity of traffic crossing internet service providers (ISPs) or autonomous systems (ASes) is generated on the Internet. Controlling the P2P traffic is therefore becoming a big challenge for the ISPs. ...

P2P systems are a natural way of supporting groupcommunication applications in MANETs. In this paper we discuss our experiences in developing such an application in the real world. We highlight limitations of legacy P2P systems, and show that solutions based on cross-layer optimisations are very promising.

Automatic speech recognition systems apply grapheme-to phoneme transcription (G2P) to model pronunciation of items in the lexicon. General purpose G2P transcriptions are not always accurate, e.g., in a multilingual environment. To improve the transcription quality, G2P transcriptions can be postprocessed using a phoneme-to-phoneme (P2P) converter. This paper discusses the applicability of P2P t...

In order to define the problems we address in this thesis, this chapter reviews the state-of-the-art in P2P recommendation systems. First, we describe centralized recommendation systems, their approaches, and limitations. Second, we discuss P2P systems as an alternative, scalable solution for decentralized recommendation systems, and extract their requirements. Finally, we evaluate the existing...

This chapter reviews core concepts of peer-to-peer (P2P) networking. It highlights the management of resources, such as bandwidth, storage, information, files, and processor cycles based on P2P networks. A model differentiating P2P infrastructures, P2P applications, and P2P communities is introduced. This model provides a better understanding of the different perspectives of P2P. Key technical ...
