Mobile phone has played an important role in daily life. Many applications on mobile phone can provide location service to user. A GPS sensor provides highly accurate localization system in outdoor environment but low accuracy over an indoor scenario because obstacles and mainly infrastructure of building block a GPS signal from GPS satellites. Moreover, GPS cannot determine a current floor that mobile...
The purpose of this paper is to describe a campus-wide indoor and outdoor positioning system developed at the School of Surveying and Spatial Information Systems at the University of New South Wales, Sydney, Australia. The system uses a Wi-Fi positioning technique known as `fingerprinting' to locate users indoors, and GPS to locate users outdoors. Fingerprinting first requires the building up of a...
Millions of people travel between countries and regions on a daily basis being exposed to unfamiliar environments. Knowing where you are and how to get to places within a restricted time can make people's lives easier. Today, WiFi access points (APs) are common everywhere, especially on university campuses, in hotels, hospitals, shopping centres, and city central business districts. This project,...
In this paper, we propose a hybrid cargo-level tracking system for logistics. We highlight the special system requirements, discuss the design issues and identify the design principles. Then we propose an innovative hybrid system. As far as we know, this is the first system that exploits both infrastructure-based and infrastructure-less positioning schemes for practical cargo-level tracking. Compared...
