Abstract

To the best of our knowledge, this is the first work that offers very low latency (0.1ms) per kNN query on 10-million-node networks on a commodity machine. This translates to a query throughput of 10,000 queries per second per commodity machine. Our experimental studies on large scale road networks show that our solutions are 1-3 orders of magnitudes faster than existing methods while our indexes are compact and can fit into main memory. In the future, we plan to further enhance the performance of kNN search with keywords.
