Abstract: This paper presents a model of network nodes, equipments, protocols, businesses for tactical communication networks based on VRNET Developer. By making use of the ray-tracing method, a wireless electromagnetic propagation model and the simulation platform closed to the actual combat environment are built for the simulation of tactical communication networks. Based on specific scenario simulation, the impacts of complicated terrain and interference to the tactical communication networks are analyzed. The main goal of the study is to provide a way for the further research on tactical communication networks.

Key words: tactical communication network, wireless propagation, interference, network simulation
