Distributed Search and Pattern Matching [chapter]

Reaz Ahmed, Raouf Boutaba
2009 Handbook of Peer-to-Peer Networking  
This chapter highlights the search requirements in large scale distributed systems and the ability of the existing distributed search techniques in satisfying these requirements.  ...  Despite of the diversity in application, these systems share common requirements for searching due to transitory nodes population and content volatility.  ...  In other words, uniform distribution of load may result into poor system performance in a large scale distributed system.  ...

Efficient Processing of XPath Queries with Structured Overlay Networks [chapter]

Gleb Skobeltsyn, Manfred Hauswirth, Karl Aberer
2005 Lecture Notes in Computer Science  
In this paper we present a first solution for efficiently supporting structured queries, more specifically, XPath queries, in structured P2P systems.  ...  Though the use of a distributed index (typically a distributed hash table) makes the implementation of structured queries more efficient, it also introduces considerable complexity, and thus only a few  ...  Conclusions In this paper we presented the efficient solution for indexing structural information in a structured overlay network used as distributed P2P storage of XML documents.  ...
