Abstract

Location accuracy problem is addressed in Location Based Tracking using mobiles. Location accuracy is a fundamental task because user needs accurate Location to track a child, a friend or culprit etc. The Mathematical Analysis is done in the paper on Location Tracking by mobile phone. A Person is tracked through Latitude Software of a Mobile. The distance of s person (Predicted distance) from different locations is determined through same software on a Mobile. Actual distances are also noted for same locations. By applying various mathematical Algorithms, the study calculates the error and accuracy level of the position of a person through Mobile. The study compares the results of different algorithms and calculates the correlation between distances that leads to conclusions and key issues for further work.
