The Designing of Indoor Localization System Based on Self-Organized WSN Using Pulson UWB Sensors

This paper presents a method for using the UWB ranging & communication modules (RCM) and designing ARM9 controllers to set up Self-organized WSN indoor localization system. It is the mobile target that measure the distance at the same time, so it needn´t to synchronize the clock of the base station and can obtain real-time position information. The most advantage is that the mobile tag can detect the base stations nearby automatically and along with these base stations to form a self-organized wireless sensor network. The localization system can apply in large indoor range and the positioning error is less than 0.2m.
