Before revision:  In this paper we present the first theoretical framework for WCL performance analysis in terms of its localization error distribution parameterized by node density, node placement, shadowing variance and correlation distance . Using this analysis, we quantify the robustness of WCL to various physical conditions and provide design guidelines, such as node placement  , for the practical deployment of WCL.
