Wireless nodes deployment is a key point for monitoring and localization of the trains in railway underground tunnels, which is critical to guarantee high-efficiency and safe operation of railway traffic. In this paper, based on the surface mapping and expansion theory, the mapping of 3D tunnel surface onto 2D domain is firstly investigated. Reliable communication links among the wireless nodes in localization are vital for successful data transmission. Then, the propagation pathloss, as well as the fading of radio signals transmitting in tunnel environments is analyzed. Also, the maximum transmission range of wireless nodes under the constraint of network connectivity is estimated according to the wireless link budget. The three grid-division (nodes deployment) in wireless sensor network (WSN), i.e., triangular-grid, square-grid, and rhombus-grid are obtained in the mapped 2D domain of actual tunnel.
