“…The PSs in [20] and [21] use isotropic antennas, which are significantly affected by multipath, causing large errors. The research in [22] and [24] have the advantage of simple configuration because the system only uses one node, but the positioning area cannot be expanded, so it can only be used in narrow rooms. The location accuracy in [23] is also higher than in the proposed PS, but the number of nodes in [20] is 4, which is larger than in the PS in our work.…”

“…In [23], a location area expansion requires an increase in the number of nodes, while it is not necessary for the proposed PS. For the fingerprint method, [24] uses SA radiated horizontally to both sides, so the system adds a screen at the back of the antenna to avoid causing a complicated multipath phenomenon that makes the PS complex. Based on the proposed antenna, we have a threenode PS based on the Zigbee standard.…”

This paper proposes the 2.45 GHz planar Beam Steering Antenna Array for Indoor Positioning Systems. The antenna array consists of a phase shifter based on a 4 × 4 Butler matrix, and an array of four dipole Yagi antennas. By choosing one of four beams using a switching controller, the main beam of the antenna can steer in four directions from +37 • , −12 • , +12 • to −36 • . The antenna has a narrow fan beam with a beamwidth in the azimuth plane of from +21.5 • to +24.5 • and in the elevation plane of approximately 90 • which effectively minimizes multipath signals. These advantages are suitable for positioning systems to increase location accuracy. The antenna achieves a peak gain of from 9.1 to 9.8 dBi in four directions, a wide band of 400 M Hz. The fully electronically steerable antenna prototype has been designed using CST software, simulated based on the finite element method, and fabricated on the RO4003C substrate as well as measured. The antenna is implemented in the Indoor Positioning System using three different location methods, including trilateration, triangulation, and fingerprinting, to highlight the antenna's advantages in improving location accuracy with the ratio between the mean location error and area of 0.051, 0.033, and 0.023 respectively.

“…Even though fingerprinting method results with promising location estimation outcome, signal map creation is time-consuming and requires to be repeated even when there is a small change in the physical setting. In addition to RSSI-based location estimation using Wi-Fi, 17 researchers have also conducted studies on localization techniques using angle of arrival (AoA), 18 time of arrival (ToA), 19 and time difference of arrival (TDoA). 20 With the recent proliferation of smartphones with Bluetooth low energy (BLE) that can communicate with other devices and affordable off-the-shelf signal-emitting beacons, the dominance of Wi-Fi use for indoor location sensing is greatly challenged.…”

Many indoor location systems utilizing the fingerprinting technique require frequent signal map generation due to the dynamic properties of indoor environments. This time-consuming task can be freed from human involvement by using various techniques. Thus, a robot-aided signal map creator is implemented and its positioning performance as well as its mapping time is compared with a widely used human facilitated approach. For testing purposes, a low-cost, low-power, not off-the-shelf signal data collection robot is implemented. Its signal collection speed and location estimation precision is then compared with the manual method both in a small and large environment.The findings indicate that in the small environment, robot-aided approach performs with 268-cm error-rate 70% of the time. On the other hand, the improved robot-aided approach in large environment saves 52 min of labor-intense legwork and achieves 303.5-cm mean error-rate.

Wireless sensor networks contain various components such as sensing nodes with computational and communicating capabilities. WSN based communication has gained huge attraction from industrial field and researchers due to its significant nature of communication in diverse scenarios in real-time applications such as military application, health monitoring, and civil applications etc. During past decade, ahuge amount of research has been carried out for improving the performance of WSN communication system. Generally, theperformance of wireless sensor network depends on the data collection, routing, and energy consumption minimization. However, these issues have been discussed extensively in previous research but theperformance of WSN is densely deployed environment still remains a challenging task. In this article, we discuss recent studies in the field of WSN. This article presents a review study on WSN routing, WSN localization and load balancing and lifetime enhancement schemes. A comparative analysis is presented based on routing and localization schemes. This study shows that the performance of WSN further can be improved by developing fault-tolerant RSSI based localization, bio-inspired routing algorithms and energy-efficient load balancing schemes.
