Ranging Technology for Accurate Localization in Short-Range Wireless Networks – A Comparative Study
Localization capability is usually required and designed for wireless networks. Although many localization algorithms have been proposed, the refinement issue of guaranteeing the location accuracy is still in its early stage of development. This paper compares different ranging technologies for localization measurement. Specifically, we analyze infrared, ultra sonic, radio frequency and ultra wideband as different choices. After a comparative study the paper recommends ultra wideband as the best candidate for accurate range-based localization system in the short-range wireless network scenario.
