Wireless network device position location system
Abstract
Location Based Services (LBS) are continuously gaining popularity and enabling a new area of innovative applications. ?e basic functionality needed in order to provide LBS is the position location of the user. Many localization systems and te?niques are already available, with the GPS being the most widespread. Since GPS is based on a network of satellites it cannot cover indoor environments and many of the positioning systems used indoors require proprietary hardware and so?ware. ?e objective of the dissertation is to investigate analytically and verify experimentally through simulations and field trials a novel approa? for the development of a positioning system. We consider IEEE 802.11-based wireless network devices and infrastructure in our positioning system, thus enabling the location positioning for the majority of contemporary mobile computing devices. Most of the localization solutions using 802.11 are based on the creation of signal strength maps, a time consuming and labor i ...
