This paper addresses efficient processing of a continuous range query with type attributes, which continually monitors only the specific types of moving objects falling within a given query region. We follow a distributed continuous range query processing strategy with the notion of resident domain, where the server pushes some query processing tasks to the moving objects¡¯ side to achieve significant savings in terms of server load as well as communication costs. We propose a novel BP-tree (Binary Partitioning tree) variant index structure called the B2P-tree (Bit-vector Binary Partitioning tree) to facilitate determining the type attributed resident domain for each moving object. The search algorithm on the B2P-tree is also discussed. Through simulation experiments, we demonstrate the superiority of our B2P-tree based method for determination of the type attributed resident domain.
