摘要
WSNs are a physical impossibility to be deployed into the area of absolute plane in the context of real-world applications. For all kinds of applications in WSNs accurate location information is crucial. In this article, we focus on 3D location accuracy in WSNs. We quantify the estimation accuracy for the TOA measurements by deriving the Cramer-Rao bound (CRB), and discuss the performance in two application scenarios, 2D WSN and 3D WSN. Matlab simulation indicates that the 3D location accuracy is superior to the 2D location accuracy for WSNs with reference devices and blindfolded devices being deployed randomly.
