“…In order to achieve accurate navigation information indoors, a number of methods for localization with various sensors and precision were proposed [1][2][3]. For instance, in [4], an RFID-based position and orientation measurement system for mobile objects was proposed by Shirehjini et al; in [5] Park proposed an indoor location system using ZigBee; in [6], Saad et al proposed high-accuracy referencefree ultrasonic location estimation. All the above-mentioned attempts employ reference node (RN) with known location to complete the localization of blind node (BN).…”

The inertial navigation systems (INS)/wireless sensor network (WSN) integration system for mobile robot is proposed for navigation information indoors accurately and continuously. The Kalman filter (KF) is widely used for real-time applications with the aim of gaining optimal data fusion. In order to improve the accuracy of the navigation information, this work proposed an adaptive extended Kalman smoothing (AEKS) which utilizes inertial measuring units (IMUs) and ultrasonic positioning system. In this mode, the adaptive extended Kalman filter (AEKF) is used to improve the accuracy of forward Kalman filtering (FKF) and backward Kalman filtering (BKF), and then the AEKS and the average filter are used between two output timings for the online smoothing. Several real indoor tests are done to assess the performance of the proposed method. The results show that the proposed method can reduce the error compared with the INS-only, least squares (LS) solution, and AEKF.

“…With the high degree of self-adaptive capacity, the network allows some or all of its nodes to move. ZigBee wireless network currently has been widely used in a variety of intelligent systems, such as personnel mine localization [2], home network control [3], [4], hospital patient care [5], [6], ecological environment monitoring [7], and children tracking [8], for its main advantages: low power consumption, network self-organizing and interoperability [8]. Unlike the above-mentioned single model applications, this paper presents a novel multiple application of ZigBee wireless network: The park lighting control and child position tracking system, which not only can control various lamps inside the park, but also can track the child that may be lost, which has a high practical meaning.…”

Based on the ZigBee wireless network, a park lighting control and child location tracking system is designed in this paper. Considering that there may be a number of children that needs to be tracked concurrently, distributed localization is needed, so an improved RSSI-based algorithm is introduced in this paper. As a goal of our system, the new method, unlike commercial digital-hardware-block based strategy used in CC2431, can be implemented by using ordinary 8-bit MCU. In the new distributed localization strategy, instead of 'lognormal', 'piecewise linear' path loss model was established, which needs only linear operation when estimating range from RSSI. Besides, min-max method, other than maximum likelihood estimation method, was used to simplify coordinates calculation. Furthermore, ZigBee compatible node modules were developed as the system hardware platform to carry out the experiments, and results demonstrate the new method has close or even better precision compared with basic algorithm, and therefore meets the demand of child location tracking system in the park.
