Among the leading technologies of research interest in recent years, Wireless Sensor Networks (WSNs) has predominantly emerged as one area extensively applicable in monitoring, controlling and surveillance. In all these areas of application, the need for performance analysis of parameters of the WSN is essential for the efficient performance of the WSN. The efficiency of the WSN depends on the localization of nodes in the network. While many factors influence the node position errors, the placement of anchor nodes can significantly impact the error. Hence it is of paramount importance to minimize localization errors. Localization errors computed by RMSE can be determined by estimating ranges and the number of sensor nodes. Also, considering the parameters that affect localization -Node density, Anchor Nodes and Communication Range, localization errors can be estimated and computed. In this research study, simulation analysis for determination of range estimates and RMSE using ToA method is computed using MATLAB.
