Study of Various Location Tracking Techniques for Centralized Location, Monitoring & Control System

Location tracking and control system require efficient resource management as well as reduction in their GSM network service cost. The data is transferred through GSM network by using SMS. This increases the system capability by efficiently managing tracking devices which could increase in number as time goes by (GPS) has become a common functionality in handheld devices, and therefore, several location-tracking applications have been developed like GPS, GPRS, IMEI number, etc.,. Some techniques consume more time, less efficiency and more error rates. Location prediction is performed by using the current location, moving speed, and bearing of the target to predict its next location. When the distance between the predicted location and the actual location exceeds a certain threshold, the target transmits a short message to the tracker to update its current location. This paper presents a various tracking Techniques for Centralized location, Monitoring & Control System.
