Indoor Localization Error Measurements with Multiple Channels

Localization has been an important issue along with the development of context-aware systems applicable to dynamic mobile environment. In this article, we deployed indoor positioning experiment on positioning platform of CC2431 based on Zigbee wireless sensor networks. In real environment we study the positioning accuracy with respect to different channel number, and the number of different reference nodes. Then, we compared location error of our location scheme with the CC2431 `location engine' and obtained lower location error. Experimental results illustrate the effectiveness of our approach on reducing location errors.
