| 4 | Tracking data management using topology of moving object database system for moving object constrained trajectory in LBS application显示文摘Advances in wireless technologies and positioning technologies and spread of wireless devices, an interest in LBS(Location Based Service) is arising. To provide location based service, tracking data should have been stored in moving object database management system (called MODBMS) with proper policies and managed efficiently. So the methods which acquire the location information at regular time intervals then, store and manage have been studied. In this paper, we suggest tracking data management techniques using topology that is corresponding to the moving path of moving object. In our techniques, we update the MODBMS when moving object arrived at a street intersection or a curved road which is represented as the node in topology and predict the location at past and future with attribute of topology and linear function. In this technique, location data that are corresponding to the node in topology are stored, thus reduce the number of update and amount of data. Also in case predicting the location, because topology are used as well as existing location information, accuracy for prediction is increased than applying linear function or spline function. | LEE Hyun jin SIM Tai jung JANG Yong ll PARK Soon young BAE Hae young | 2004 | 重庆邮电学院学报(自然科学版)2004，16，5： | 1 |
