A Simple and Efficient Iterative Method for Toa Localization
Yanbin Zou, Huaping Liu
Abstract
This paper develops a simple and efficient method for source localization using signal time-of-arrival (TOA) measurements. There exist many TOA localization algorithms, most of which require matrix inversions. Their complexity often makes them unsuitable for cases when a large number of sources need to be localized simultaneously via many sensor nodes. The proposed algorithm, which requires addition, multiplication and taking root-squares only, has a lower complexity while it still performs better than existing schemes.
