Abstract

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 9.0px Helvetica} In recent years, several techniques based on location have been developed, allowing for services based on location with different degrees of precision. The possibility of using different techniques varies between devices and regions in space, according to the available hardware on the equipment and the infra-structure. This article presents the Uni- fied Cooperative Location System, which allows the use of every available technology to a mobile device, providing a higher availability of location services. Additionally, the system implements an information exchange mechanism, allowing devices to gather location information from nearby users, like GPS or Wi-Fi, which would otherwise be unavailable for some. The possibility of exchanging GSM information provides a viable solution for the gathering of multiple GSM signals by one device, thus significantly increasing location accuracy with this technology.
