Description

There are two stages in our experiments, one is to find the predicted values of the signal strengths (RSSI’s) by using Grey prediction algorithm and second is to find the location coordinate of the mobile user by using Dynamic Triangular Location method. We have used grey prediction to predict the tendency of RSSI at rum-time stage and present analysis of predicted RSSI when mobile user is moving. Grey perdition is able to reduce the fluctuation of RSSI when mobile is moving. Location algorithms with grey prediction achieve smaller mean distance error.
