Indoor position System using KNN algorithm

Research proposal to show how KNN will increase the acuracy of Indoor Positioning Systems. The algorithms are to be tested on research tools, preferbly Omnetpp. I want two results to compare! The one with KNN algorithim and the other with only triangulation algorithms. The algorithm uses RSSI from RFID tags to estimate the position. Also along with KNN kalman filter is used to increase the accuracy. I need to see openly how the algorithms works.
