Research And Implementation Of Wireless Communication Network Deployment System Based On Electronic Map

In the information war,the planning of wireless tactical network plays an important role.With the moving digitalization process in the military field,the existing network planning methods are difficult to meet the needs of the increasing variety and quantity of communication equipments in the tactical network.This paper uses the geographic information and electronic map platform to build a wireless communication network deployment system.This system can manually or automatically add wireless communication equipments,simulate network planning,complete the analysis of electromagnetic wave propagation attenuation,build network topology,etc.,display the results on the electronic map,and ultimately achieve the purpose of reducing costs,improving the automation level of network planning,and improving the efficiency of wireless network planning.First,Digital Elevation Model(DEM)data is introduced to expand the data dimensions that Baidu Maps JavaScript API can handle.By sampling,interpolating and mapping the rasterized DEM data,a three-dimensional coordinate system of latitude and longitude-elevation values is established.The electronic map module realizes the analysis and management of terrain data.This module can handle functions such as marking any latitude and longitude device in the designated area,drawing designated communication links,and displaying the prediction results of wireless electromagnetic wave propagation attenuation,etc.Then,based on the ITU-R.P526 model,the equipment and communication link propagation attenuation prediction in the deployment area is realized.The ITU-R.P526 model is deeply discussed and the diffraction propagation algorithm calculation is summarized in detail,and C++ is chosen for digital modeling and programming.The electromagnetic wave transmission attenuation prediction results will not only be visualized in the electronic map module,but also serve as a theoretical reference for subsequent network topology generation.Thirdly,the method of constructing communication network topology is studied.The index of survivability in communication network is analyzed,and the algorithm of survivable network topology generation based on the number of disjoint paths is mainly studied,and the network topology is showed on the electronic map.Finally,based on the above research results,a wireless communication network deployment system is built,the basic software architecture is designed,and the relevant code is written and tested to reach the level that can be launched.
