Recently, the need for LBS (Location Based Services) is increasing due to the widespread of mobile computing devices (e.g. PDA, cellular phone, and notebook computer) and positioning technologies (e.g. GPS and RFID). In LBS, there are many applications that need to manage moving objects (e.g. taxies, persons). The MODB (Moving Objects DataBase) usually are used for the purpose of managing the moving objects. However, MODB only supports pull-based queries, although push-based queries are necessary for the monitoring application which is one of the important applications of LBS. In this paper, we extend functionalities of MODB to support push based queries. To achieve this goal, we suggest new data model, query language, and architecture.
