In contrast, the present invention provides a system that enables a student to answer one or more questions of a problem set. Next, the system stores information for each answer of the one or more questions over a period of time, analyzes the information for each student answer in a longitudinal manner, and identifies one or more deficiencies in learning of the student based on the longitudinal analysis. In this way, the system uses longitudinal analysis to identify student deficiencies, which allows a teacher or parent, using the analysis, to increase the quality of learning for the student. | 11-04-2010 |

The node with the best QoE is elevated to anchor. This process gradually increases the number of available anchors in the network and hence the position accuracy for additional nodes.
