Devices location in 802.11 infrastructure networks using triangulation

Abstract

Due to the great development in computer technologies and the popularity of WLANs, new services related to mobile computing can be developed. In this sense, location-based computing can be used by applications running in portable devices for taking better decisions and improving their performance. As the received signal strength (RSS) from several access points varies with position of device, we based on it for location determination of portable devices. In this paper, we present a location system for IEEE 802.11 infrastructure networks based on triangulation method. This system uses a SNMP framework to collect RSS in the portable devices and communicate it to a server where the location of devices is determined and available via http.
