Several variations to the distance join operation such as UnOrdered, Incremental, topk, Semi-Join impose additional constraints on the distance between the object pairs in P, the ordering of object pairs in P, and on the cardinality of P. A distance join algorithm on spatial networks is proposed that works in conjunction with the SILC framework, which is a new approach to query processing on spatial networks. Experimental results demonstrate up to an order of magnitude speed up when compared with a prominent existing technique.}, keywords = {location-based services, path coherence, Query processing, SILC framework, Spatial databases, spatial networks}, isbn = {1-59593-529-0}, doi = {10.1145/1183471.1183506}, url = {http://doi.acm.org/10.1145/1183471.1183506}, author = {Sankaranarayanan,Jagan and Alborzi,Houman and Samet, Hanan} }
