Abstract

Wireless sensor networks (WSN) have evolved quickly in recent years, leading to systems such as RF and Zigbee, which are commonly adopted in lights, curfew, elderly - nursing. However, RF and Zigbee system are seldom integrated effectively. This study presents a system built like WebNet, expressed in terms of UML. The proposed system behaves like Zigbee with NS2, since it combines RF with a real-time location system. It can be applied to equipment and staff tracking, and is effective for equipment and asset management. The wireless transmission condition of Zigbee is simulated by NS2, and compared with the actual result. In addition to Zigbee gateway interface, the indoor location system is formed to from the Zigbee badge and Zigbee location node, and transmits information about the current situation and relative position of the equipment to WebNet through an Ethernet connection.
