Abstract

There are three main indoor localization technology： the optical, the radio (Wi-Fi, UWB, and Zigbee) and Ultrasonic. The paper focus on analyze the performance of the Ultrasonic and Zigbee location technology. In localization technology of Zigbee, the communication delay and packet loss will influence its accuracy, and in Ultrasonic the obstacle will block its location process. So, the local and global combine technology of ZigBee based on RSSI is proposed and simulated in the paper.
