We present an efficient mapping scheme based on p-stable Locality Sensitive Hashing to assign hash buckets to peers in a Chord-style overlay network. To minimize network traffic, we process queries in an incremental top-K fashion leveraging on a locality preserving mapping to the peer space. Furthermore, we consider load balancing by harnessing estimates of the resulting data mapping, which follows a normal distribution. We report on a comprehensive performance evaluation using high dimensional real-world data, demonstrating the suitability of our approach.}, biburl = {http://www.bibsonomy.org/bibtex/288e74a2c6c5f572063c5f6765be1a550/nepomuk}, keywords = {dimensionality from:bdarla high knn nearest neighbor p2p search}, }
