A moving k-nearest-neighbor (MKNN) query is a contin-uous k-nearest-neighbor (KNN) query issued by a moving object. As both the query owner and other mobile objects are moving, the inuenced area (i.e., cells in the cellular networks), and query result of a MKNN query change with time. Existing processing techniques for MKNN queries are all centralized approaches which rely on the location up-date messages from moving objects. However, these ap-proaches typically employ complex data structures and al-gorithms. Moreover, the server may not be able to cope with a high location report rate which is necessary to ensure ac-curate and correct answers. In this paper, we propose a distributed strategy to process MKNN queries in real-time. In our sch...
