The objective of this study is the assessment of the accuracy of the operation of three indoor localization platforms based on wireless short range technologies: platform of UWB-based localization, platform of RFID-based localization and domotic platform based on BUSing protocol.
LANDMARC algorithm achieves satisfactory location accuracy with less reader by introducing active reference tags, usually placed in the form of regular grid and served as neighbors for the tracking tags. However, the uniform arrangement of the reference tags is not applicable in the case that the probability occurrence of each area differs greatly, or obstacles like wall and partition exist. The paper...
Indoor location technology and its applications are a prerequisite for Ubiquitous Computing .The paper introduces the LANDMARC algorithm for indoor location, provides the direction for the experiment and implement of LANDMARC, and then the improved nearest neighbor algorithm is proposed to improve the accuracy. At last the simulation results show that the improved algorithm is better than the original...
This paper aims to locate a tag position inside the building by using low cost device with minimal location error. The enhancement approach with received signal strength indication (RSSI) technique is proposed to achieve the target. In this paper, after introducing the existing LANDMARC system, we try to construct the relationship between RSSI and distance from reader to tag by experiment. Finally,...
This paper analyzed the relationship between the nearest neighbour algorithm and the topology of reference tags used in LANDMARC, and proposed an optimal arrangement of reference tags. Simulation results showed that the new topology can provide better performance than the old one used in LANDMARC.
This paper deals with the problem of personal location and guidance in indoor and outdoor environments. The authors analyze different technologies which can be applied to this task. The goal is providing the user with the most accurate and reliable technology depending on the user profile and environment. Indoor location technologies are analyzed and compared from different points of view, highlighting...
RFID technologies are getting more attention for its good performance in many application domains. Indoor location based on active RFID technologies provides an approach with a high performance to price ratio, which further expands the application domain. This paper proposes a new algorithm, which is based on analysis of LANDMARC algorithm and the general Bayesian-based algorithm. Our algorithm is...
