“…Traditional protocols such as ALOHA or slotted ALOHA [30] have poor efficiency in terms of the successful number of transactions. Hence, similar to [24], [31], we consider an STDMA approach in which one TDMA slot is needed for a TW-TOA transaction, but two transactions can occur simultaneously if they do not interfere. The total STDMA delay within one time slot 1 depends only on the network topology in the current time slot.…”

Abstract-Ultra-wide bandwidth (UWB) systems allow for accurate positioning in environments where global navigation satellite systems may fail, especially when complemented with cooperative processing. While cooperative UWB has led to centimeter-level accuracies, the communication overhead is often neglected. We quantify how accuracy and delay trade off in a wide variety of operation conditions. We also derive the asymptotic scaling of accuracy and delay, indicating that in some conditions, standard cooperation offers the worst possible tradeoff. Both avenues lead to the same conclusion: indiscriminately targeting increased accuracy incurs a significant delay penalty. Simple countermeasures can be taken to reduce this penalty and obtain a meaningful accuracy/delay trade-off.

“…The total STDMA delay within one time slot 1 depends only on the network topology in the current time slot. In contrast to [24] and [31], we do not consider ranging packet aggregation or other enhancements, as they are hard to justify with real hardware due to the tight synchronization constraints.…”

This paper deals with Medium Access Control (MAC) techniques adapted to location applications in Ultra Wideband (UWB) Low Data Rate (LDR) wireless networks for which low power consumption, low complexity location and relaying capabilities are identified as critical features. In comparison with the IEEE 802.15.4 MAC, the proposed solution is completely described by the use of self-contained beacons. We introduce here some of the supported functionalities in compliance with recent Low Duty Cycle (LDC) requirements. Under realistic ranging models, we also evaluate the performance of joint ranging/positioning procedures through event-driven packet-oriented simulations.

From the Characterization of Ranging Error to the Enhancement of Nodes Localization for Group of Wireless Body Area Networks

International audienceTime-based localization in Wireless Body Area Networks (WBANs), has attracted growing research interest for the last past years. Nodes positions can be estimated based on peer-to-peer radio transactions between devices. Indeed, the accuracy of the localization process could be highly affected by different factors , such as the WBAN channels where the signal is propagating through, as well as the nodes mobility that bias the peer-to-peer range estimation, and thus, the final achieved localization accuracy. The goal of this paper consists in characterizing the impact of mobility and WBAN channel on the ranging and localization estimation, based on real mobility traces acquired through a motion capture system. More specifically, the ranging error is evaluated over all the WBANs links (i.e. on-body, off-body and body-to-body links), while an impulse Radio Ultra-Wideband (IR-UWB) physical layer, as well as a TDMA-based Medium Access Control (MAC) are playing on. The simulation results show that the range measurement error can be modeled as a Gaussian distribution. To deal with the gaus-sianity observation of ranging error and to provide high positioning accuracy, an adjustable extended Kalman Filter (EKF) is proposed
