“…The crystal used for microcontroller is 7.3728 MHz with baud rate is set at 9600 bps.LCD display and ZigBee module are interfaced to port C and D respectively. The existence of automation device profiles and low power consumption (min.60mW) as compared to Bluetooth makes the ZigBee [9][10][11] an ideal wireless interface for automation devices [7].The ZigBee addresses of sensor nodes selected in the network have the id as S1 (406FDB22), S2 (406FDBD6) ,S3 (406FD976) and S4(406FDB51).…”

“…For this scenario, numerous time-based localization technologies have been applied in the literature, including commercial communication infrastructure, such as wireless local area networks [23] and personal area networks [24,25], as well as specialized ranging and positioning systems such as chirp spread spectrum [26]. In this context, the impulse-radio ultra-wideband (IR-UWB) technology, cf.…”

In this paper, we consider the schedule-based network localization concept, which does not require synchronization among nodes and does not involve communication overhead. The concept makes use of a common transmission sequence, which enables each node to perform self-localization and to localize the entire network, based on noisy propagation-time measurements. We formulate the schedule-based localization problem as an estimation problem in a Bayesian framework. This provides robustness with respect to uncertainty in such system parameters as anchor locations and timing devices. Moreover, we derive a sequential approximate maximum a posteriori (AMAP) estimator. The estimator is fully decentralized and copes with varying noise levels. By studying the fundamental constraints given by the considered measurement model, we provide a system design methodology which enables a scalable solution. Finally, we evaluate the performance of the proposed AMAP estimator by numerical simulations emulating an impulse-radio ultra-wideband (IR-UWB) wireless network.

“…Systems such as that described in [7] are implemented using off-the-shelf short-range wireless communication systems. Furthermore, for applications in which coarse distance information may be considered sufficient and accurate positioning is not a strict requirement, proximity detectors may be used, such as the nearly omnidirectional ZigBee-based proximity detection technique described in [8].…”

This paper presents research to develop an ultrawideband ranging sensor for personnel indoor localization based on the measurement of the pulse round-trip time. An approach combining flexibility, a high measurement update rate, and asynchronous operation with digital processing capability has been employed in the design of the sensor. The principle of operation, the architecture of the realized sensor, and the experimental setup are described. Finally, the results of a ranging calibration and validation test are presented and discussed. In the validation procedure, a root-mean-square error of 29 cm and a maximum absolute error of 81 cm with an operational range of approximately 10 m were observed.
