Abstract

In this paper, the proposed methodology calculates the distance between two nodes in Wireless Sensor Network for localization purpose. The methodology is a variant of Time of Arrival (TOA) methodology. The simulations are done in Matlab using Ultra wide band spectrum and Gaussian monocycle pulses. The measured distances are compared with set distances and mean square errors are calculated. Finally, the set distance and measured distances are compared for various transmission frequencies within UWB spectrum.
