... for line-of-sight (LOS) situation in WSNs. However, one of major problems for accurate localization in WSNs is non-line-of-sight (NLOS) propagation. This article proposes two CRLBs for WSNs localization ... discussed in [23,25]. In this article, two CRLBs compatible for var- ious distributions of NLOS errors for WSNs localization in NLOS environment a...
