Write-heavy applications present a challenge to peer-to-peer indexing methods which need to update the index for each write operation. The costs incurred when the distributed index is updated becomes a bottleneck. Current distributed indexing methods are designed for indexing and retrieving single tuples, giving a very high update cost. In this paper we present a new approach to efficient peer-to-peer...
Due to applications and systems such as sensor networks, data streams, and peer-to-peer (P2P) networks, data generation and storage become increasingly distributed. Therefore a challenging problem is to support best-match query processing in highly distributed environments. In this paper, we present a novel framework for top-k query processing in large- scale P2P networks, where the dataset is horizontally...
