Abstract

Asset localization implies adding more features in wireless sensor networks, such as object searching and tracking capability. 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 Time of Arrival (TOA) scheme using IEEES802.1S.3a channel model is implemented using Matlab and tested. In this method only two reference nodes are used for localization, which decreases the overall power consumption through reducing number of packets exchanged in the system while reducing packets collision probability.
