Aspects of Adaptivity in P2P Information Retrieval [chapter]

Wolfgang Müller, Andreas Henrich, Martin Eisenhardt
Lecture Notes in Computer Science  
Helping the user find relevant information in a P2P network is the subject of the field of Peer-to-Peer IR. In order to be successful, a P2P-IR system needs to be adaptive in several respects.  ...  Within this article we detail the motivations and challenges of P2P-IR, as well as the ways in which P2P-IR systems adapt and where improvement is needed in order to achieve adaptive multimedia retrieval  ...  We identify four main aspects of adaptation that a P2P-network has to perform.  ...

Adaptive Erasure Resilient Coding in Distributed Storage

Jin Li
2006 2006 IEEE International Conference on Multimedia and Expo  
In this paper, we investigate the use of adaptive erasure resilient code (ERC) which changes ERC fragment size according to the size of the file distributed.  ...  We show that the adaptive ERC may greatly improve the efficiency and reliability of P2P storage. A number of design policies and strategies for the P2P storage application are also investigated.  ...  Each doubling of k results in 52%, 61%, 71%, 78%, 84% more peers to store information. Doubling of k also requires at least double number of peers during information retrieval.  ...
