Abstract

Asset tracking is a critical problem in modern data centers with modular and easily movable servers. This paper studies a wireless asset tracking solution built using wireless USB (WUSB) radios that are expected to ubiquitous in future servers. This paper builds on our previous work on direct ranging using WUSB radios and studies algorithms for data center wide localization of all rack mounted servers. The results show that it is possible achieve very low error rates in localization in spite of very stringent constraints (i.e., each server being just 1.8" high) by exploiting the properties of the data center environment.
