In real-time moving object tracking, each time an object moves, a new position should be sent from the moving object to the server. In this case, numerous moving objects cause a very large volume of location updating. It could bring communication, computation and update overhead between moving object and server. This paper proposes a new location tracking method that is applicable to continuous updating of current position of moving object. The techniques are based on movement anticipation with pre-evaluated arrival time information; the moving object compares actual position with anticipated position at predefined time interval and checks deviation between two positions. Only if predefined threshold exceed, the location updating, from moving objects to the server, is occurred. Using predefined route information, this approach is effective with update reduction for real-time tracking of moving object.
