Location-Based and Content-Based Information Access in Mobile Peer-to-Peer Computing: The TOTA Approach
[chapter]
2004
Lecture Notes in Computer Science
Preserved Fulltext
The TOTA middleware takes care of both propagating tuples across a network on the basis of application-specific rules and of adaptively re-shaping the resulting distributed structures accordingly to changes ...
Mobile peer-to-peer computing calls for suitable middleware and programming models to provide dynamic access to information and resources in dynamic network environments. ...
In addition, one could think at mapping the peers of a TOTA network in any sort of virtual space. ...

Agents can inject these tuples in the network, to make available some kind of contextual information and to interact with other agents. ...
Here we show how the middleware TOTA (Tuples On The Air) supports self-organization by providing effective abstractions for the above two building-blocks. ...
Taking this approach to the extreme, one could think at mapping the peers of a TOTA network in any sort of virtual overlay space [Rat01] , and propagating tuples in such virtual space. ...

To implement such an approach, one can rely on distributed tuples injected in a network and propagated to form a distributed data structure to be sensed by application agents. ...
However, to gain the full benefits from such a coordination approach, it is important to enable the distributed tuples to preserve their structures despite the dynamics of the network. ...

In this work we study how to process complex queries in DHT-based Peer-to-Peer (P2P) data networks. Queries are made over tuples and relations and are expressed in a query language, such as SQL. ...
Each data object is mapped to a point in d-dimensional space and then the request is routed towards the mapped point in the virtual space. Each peer on the path passes the ...
They also build a hierarchical identifier space on top of the flat identifier space, by partitioning the identifiers in multiple fields, in order to manage multiple data structures. ...

Structured P2P systems in the form of distributed hash tables (DHT) are a promising approach for building massively distributed data management platforms. ...
In this paper, we argue that in order to cope with the dynamics in large-scale P2P systems such query techniques should be work in a best effort manner. ...
Conclusion and Outlook Best effort query processing is an important challenge on the way to an SQL-like query processor on top of structured P2P networks. ...
