“…Therefore, UWB becomes attractive in different applications like tracking [16]. UWB operates by transmitting and receiving an exceptionally short duration burst of RF energy-typically a few tenths of a picosecond to a few nanoseconds in duration [17]. By utilizing both of technology (UWB) and technique (TDOA) which is chosen to provide good accuracy for LPS.…”

Local position system (LPS) becomes more and more diversified and increasingly important in large numbers of applications and contexts such as healthcare, targeted, monitoring, tracking and security. In LPS, three anchors at least with known position are employed with one tag for localization. In this paper, LPS which contains three anchors and one tag is used to get positioning. Tag position represents user location. It estimates by using UWB technology which sending signal based on triangulation method with assist of Labview. By using Labview coding the position of each anchors can be read successful after connection all anchors and tag with PC and router. The positioning of tag in (x, y) direction, successfully update immediately when tag moving which is shown in graph. Therefore, the Graphical User Interface (GUI) for LPS based on Labview is achieved to determine the user positioning with positioning error less than 17cm. We believe this paper would catalyze further investigation by the researcher which deal with both of LPS field and Labview. Index Terms-Local positioning system, anchors, tag, UWB, graphical user interface, Labview. 2 , 2 represent position of the receiver 2,(both are known position ). (x, y) is unknown position of source position.

“…In [35] we have presented the single-sided asymmetric TWR (SSA-TWR) protocol and reported the results of its extensive evaluation, assessing the feasibility and efficiency of the proposed protocol. Also these measurements revealed the strong effect of the various communication parameters on the accuracy of UWB localization for the tested protocol as well as for the basic TWR and SDS-TWR protocols, which were used as the references for comparison.…”

“…The nodes were programmed with the in-house developed software composed of the UWB transceiver drivers and the modified software implementing the SSA-TWR protocol. The original SSA-TWR software [35] was modified to enable support for more anchors and to handle the automatic switching of the modes. Also a special Javabased application has been developed for a laptop to automatize the mode switching and data logging.…”

“…Note that for all the modes in the experiment block, the TA RSP was fixed at 15 ms. Given the proven strong effect of the TA RSP on the accuracy (refer to [35]), motivation of this choice may not be obvious. The reason for setting this value is that in order to characterize the effect of the communication parameters, all the modes should be tested with the same TA RSP value.…”

The ultrawideband (UWB) radio signals are known for their good time resolution enabling implementation of accurate localization and tracking. The recent appearance of commercial UWB transceivers in masses on the market has boosted the interest towards this technology and facilitated its use not just for research, but also for business. In this paper we focus on the problem of UWB-based wireless indoor localization of machines and humans by means of IEEE 802.15.4-2015 high rate pulse repetition (HRP) UWB technology and specifically the accuracy of such localization. Namely, we report the results of an extensive experimental study revealing the effect of various communication settings on the accuracy of indoor localization for an asymmetric localization protocol. The conducted experiments lasted over 200 hours almost nonstop and involved transmission of more than 30 million ranging packets. In the experiments we have tested over 200 different modes and explored the effect of seven different parameters on the UWB ranging performance. The presented results reveal that the communication settings need to be accounted when determining the time of flight using UWB. Also we show that the accuracy of ranging is strongly affected by the used channel, data rate and pulse repetition frequency. Finally, we note that the increase of the UWB transceiver's temperature due to self-heating has a strong effect on the results of the localization.

In this paper we address the problem of increasing the flexibility of the contemporary wireless sensor and actuator networks (WSANs) in regard to the design of the nodes. For this we propose the concept of a Plug&Play enabled modular WSAN node platform. According to our concept, the new WSAN nodes with desired functionalities can be built by stacking together the different hardware modules encapsulating power sources, processing units, wired and wireless transceivers, sensors and actuators, or even sets of these. Once a node is built, it automatically discovers and identifies all the connected hardware modules, obtains required software and tunes its own operation taking into account the node's structure, available resources and active applications. In this paper we first present the concept and then report the developed hardware and software architectures and the most critical mechanisms enabling implementation. Also we discuss the practical implementations and report the evaluation results for the prototyped solution. Our results show that the developed platform is much more feature and resource rich than the existing ones, which is achieved at a cost of increased consumption and size. We believe that the unique features of the proposed platform have the potential to drastically change the procedure of WSAN development, especially when it comes to experimenting and developing dynamic WSANs with a heterogeneous structure. In this respect the hardware identification and reconfiguration capabilities conceived in the platform can be utilized in full and may drastically increase the performance of WSANs, if combined with novel control and optimization schemes yet to be developed.
