Localization of wireless sensor networks using mobile anchor nodes

Abstract

Wireless sensor networks (WSNs) are an important class of pervasive computing environments. WSNs have been described as a new instrument for gathering data about the natural world, extending the reach of our human senses. WSN applications are dominated by constrained resources such as energy, computing power, storage and communications bandwidth. An important aspect of WSN operation is the geolocation of all the sensor nodes. Automatically determining sensor position after deployment will improve the reporting of the origin of events in indoor and outdoor applications, in areas such as environmental monitoring, target tracking and disaster relief operations. This thesis explores the use of a mobile anchor moving through a sensor

Geographical Information System: Application to the Geolocation of the Nearest Health Facilities in the Town of Kananga

“…very close to that of light = 3*1088 m/s. For (H. Amel, 2015), the satellite positioning system works on the principle of triangulation. Again, the position of the observed object is calculated from the signals exchanged between the receiver it is equipped with and a set of at least 3 satellites forming a constellation.…”

GeoHealthTrack: A Geometry-Driven Positioning Algorithm for Enhanced Healthcare Asset and Personnel Tracking in Smart Hospitals

“…Smart hospitals, characterized by the incorporation of cutting-edge technologies, have emerged as a cornerstone in revolutionizing the healthcare landscape. As the healthcare sector continues to evolve, there is a growing need for innovative solutions that optimize the tracking and management of healthcare assets and personnel within these intelligent healthcare environments [1][2][3].…”
