Abstract: The invention discloses a system for monitoring a railway network infrastructure, the system comprising: at least one sensor node configured to obtain at least one sensor data; at least one processing component configured to: process the at least one sensor data, and generate at least one processed sensor data; at least one analyzing component configured to generate at least one railway network infrastructure hypothesis based on at least one of: the at least one sensor data, and the at least one processed sensor data.

Abstract: The invention relates to automatically determining an efficient topology of sensor network preferably installed in an infrastructure, such as railway infrastructure. The invention discloses a system, a method, a user device. The invention further provides a processing component configured to receive sensor data from at least one or a plurality of sensor node(s). Further, the invention provides a trajectory module, configured to generate at least a part of trajectory data based on sensor data.
