Abstract
This paper proposes a sudden large area intelligent identification and early warning method
using the algorithm of neural network to predict the future users village
relying on the K-Means clustering algorithm and Apollo mourinho’s basic value theorem to determine the area of and through linear regression algorithm for comparison between the predicted value and basic value
determine the early warning area according to the longitude and latitude of the warning area
build the Delaunay triangulation
determine the early warning area of the base station coverage
neighbourhood relations
the latitude and longitude information on surrounding site together
using the crawler technology for base station coverage boundary
