Motivated by this observation, this paper studies the problem of efficiently processing k nn k - ge 1 search on r - tree - like structures storing historical information about moving object trajectories. two algorithms are developed based on best - first traversal paradigm, called bfp k nn and bft k nn, which handle the k nn retrieval with respect to the static query point and the moving query trajectory, respectively. both algorithms minimize the number of node access, that is, they perform a single access only to those qualifying nodes that may contain the final result
