Abstract


In the mobile communication networking , the current best land mobile communication network is a cellular system of the mobile communication system . The the regular hexagonal coverage area of ??the cellular system of the mobile communication system divided FIG actually as a parent point is to the base station , and the Voronoi diagram when the case of master points are evenly distributed . Painting traditional computational geometry Voronoi diagram , there are some defects in practical applications : ■ ignores the external boundary of the base station ■ coverage area is divided , however , based on all the way to the antenna , rather than sector units article first Voronoi the diagram of the traditional algorithm of the bipartite graph Delaunay network improvements , followed by the indirect method Voronoi diagram algorithm . Improvement made ??in the practical application of Voronoi diagram algorithm Voronoi diagram of five applications in the mobile communication network optimization : ■ divided ■ radio signal field strength measured point select ■ cellular system mobile communication base station coverage cell capacity estimates ■ additional the station ■ base station field strength prediction contour from the engineering point of view , combined with MapInfo geographic information system , MySQL database systems , object - oriented technology , the Voronoi diagram in the mobile communication network optimization package into modules , the development of GSM / GPRS wireless network optimization sub-module of intelligent decision support system - Voronoi subsystem .
