Construction of Emergency Communication Network with Multi Constraints Based on Geographic Information

Aiming at the problem of deploying the vehicular relay station in the construction of emergency communication network, OpenStreetMap and FME tools are used to construct the electronic map which contains the geographic information such as roads and rivers. A Method for judging the line of sight propagation is also studied. The simulation results show that the proposed algorithm can be more reasonable and applicable to address the vehicle relay station, and can fulfill the requirements of the actual emergency communication link construction better.
