Abstract: Real-time location systems (RTLS) help ensure that assets are in the right place at the right time. There are numerous possible applications afforded by tagging assets such as improving routing and multiple access control protocols in wireless sensors network which prolong its operational life time. Ultra Wideband (UWB) wireless technology offers greater resistance to multipath fading, interference, and potentially lowers power consumption. Therefore UWB technology inherently enables the accurate localization of assets. In this paper, localization method based on a passive Time difference of Arrival (TDOA) scheme using IEEE802.15.4a ”industrial environment” channel model is implemented using Matlab and tested. A new proposed waveform based on Gaussian pulse is used for localization, which decreases the interference between the UWB and other signals, and decreases the probability of error (prb). The proposed localization scheme decreases the error between real asset location and estimated position at low level of signal to noise ratio (E/No).
