Adaptive processing of historical spatial range queries in peer-to-peer
We investigate the problem of processing historical queries on a sensor network. Since data is considered to have been already collected at the sensor nodes, the main issue is exploring the spatial component of the query in order to minimize its cost represented by the energy consumption.

Efficient way of Data Managing for Range Queries in Unstructured Peer
2005. Abstract Many emerging applications that use XML are distributed, usually over large peer-to-peer (P2P) networks on the Internet. The deployment of an XML query shipping system over P2P networks requires a specialized synopsis to capture XML data in routing tables.
Robust and efficient aggregate query processing in peer-to-peer networks
We introduce so-called Super-Peers which structure a P2P network. Using this Super-Peer based network we "unroll" queries. This allows us to execute even user-defined operators nearby the data ...

Robust and efficient aggregate query processing in peer-to-peer networks
The ability to approximately answer aggregation queries accurately and efficiently is of great benefit for decision support and data mining tools. A P2P network consists of numerous peer nodes that share data and resources with other peers on an equal basis. Unlike traditional client-server models, no central coordination exists in a P2P system; thus, there is no central point of …

Improving Search in Peer-to-Peer Networks
network, nodes spend processing resources (i.e., cycles) to forward the query, process it, etc, and bandwidth to send and receive messages. The main cost of queries are there-fore bandwidth and processing. Since the cost of a query is not incurred at any single node in the network, it makes sense to discuss costs in aggregate (i.e., overall the ...
