A Distributed Approach to Continuous Monitoring of Constrained k-Nearest Neighbor Queries in Road Networks
Given two positive parameters k and r, a constrained k-nearest neighbor (CkNN) query returns the k closest objects within a network distance r of the query location in road networks. In terms of the scalability of monitoring these CkNN queries, existing solutions based on central processing at a ser...
