Development and evaluation of Zigbee node module for USN

This study aims at securing technology to develop a multisensor and complex position-tracking Zigbee node module for USN (ubiquitous sensor network). In a concrete way, it aims at developing military (invader detection module and system) and industrial (transformer-tracking and thermo-measurement module and system) Zigbee telecommunication node module, and developing wireless monitoring and tracking technology based on such modules. In addition, it aims at building up the foundation of interface test for various sensors (thermo sensors, pressure sensors, vibration sensors and vision sensors) and the foundation of a comprehensive interlocking device to which GIS (Geographic Information System) and GPS (Global Positioning System) were applied, for industrial devices are mostly installed in mountains. Moreover, it aims at developing a roaming-type variable Zigbee node module to the end that it stands against unfavorable conditions (extreme temperatures, dust, winds, electromagnetism, noise, etc.). In case such aims are achieved, Zigbee communications will not be limited to normal and stable conditions (home networks, building automation, etc.) but will be applied to the industrial field under noises and unfavorable conditions. In such a case, the application of Zigbee node modules is expected to be unlimited.
