Abstract
AbstractThis paper mainly provides one new nature inspired Energy Conversation Optimization (ECO) method to search for the optimal sensor position of sensor network in the typical tunnels, fully covering the tunnel and dynamically locating the high-speed train in the tunnel. Firstly, one objective of this study is to briefly introduce the framework of transmitting the sensor's data in the railway network, the objectives and the constraints of the optimal coverage problem. Secondly, another objective of this paper is to provide some fundamental assumptions and concepts of ECO algorithm, together with the corresponding convergence analysis and the main steps of ECO algorithm. Additionally, the ECO algorithm is mainly utilized to address the optimal tunnel coverage problem. Numerical results mainly concentrate on the effectiveness of ECO algorithm comparing with the PSO algorithm and deal with four typical optimal coverage problems in the presence of the line tunnel, the indirect line tunnel and the complica...

Summary
Comparing with other transportation methods, railway transportation has the advantages such as the huge transportation capacity, the high speed, the low transportation cost, the high safety and the low pollution, etc. Most of the currently and efficiently existing methods of train location [1, 2] on the basis of global position system (GPS) system and Beidou system (BDS) can provide the position service with high precision, leading to the huge transportation capacity. The problem of locating the train in the mountainous tunnel plays a great role on the safety and the efficiency of railway transportation in the presence of the China’s west, since there exist a large number of the mountainous tunnels along the railway. The dynamical locating of highspeed train in the mountainous tunnel is one of the important and interesting topics in the field of the current and future modern railway transportation
