Popis: As spatial data being collected by various industries (e.g., telecommunication, insurance, automotive) is on the increase, indexing and answering queries extremely quickly is necessary. This paper proposes a new mechanism, Mobile PATRICIA-trie (MP-trie), for fast queries on moving objects that provides a 1000x improvement in performance over state-of-the-art spatial indexing mechanisms. We reduce the problem of spatial indexing to that of prefix-matching over binary strings, which is then coupled with off-the-shelf commercially available content-addressable memory (commonly used in IP routers for forwarding table lookups). We validate our approach on data collected from a real-world deployment in Stockholm, Sweden across 2000 cars for a period of one month.
