Positioning techniques are known in a wide variety of wireless radio access technologies. Traditionally, Global Positioning System (GPS) is the most popular outdoor positioning system. Localization also exists in mobile networks such as Global System for Mobile communications (GSM). Recently, Wireless Local Area Networks (WLAN) become widely deployed, and they are also used for localizing wireless-enabled...
The development of a positioning algorithm on the board of a moving object using the information about the direction of signal reception from global system for mobile base stations. The developed system may be used as the effective and reliable method of positioning. Mobile module can help to solve all the types of positioning problems.
In this paper, we consider the problem of positioning, travel direction detection and speed estimation of GSM-based mobile phones. Many techniques are proposed using several technologies like GSM, UMTS or WiFi. Once these technologies are mature enough to be deployed, they will have significant impact on automotive telematics and modern public transit systems. We produce a technique for speed estimation...
Mobile telephony (e.g. GSM) is today's most common communication solution. Due to the specific characteristics of mobile communication infrastructure it can provide further real added value to different third parties. Using location information and mobility patterns, it not only contributes to emergency planning as well as safety and security, but also is a driving force behind new commercial services...
Cyber foraging is a pervasive computing technique where small, mobile devices offload resource intensive work to stronger, nearby surrogate computers in order to preserve energy and achieve better performance. The problem with relying only on local resources is, that the availability of such resources may be scarce in many environments. In this paper we therefore argue that a third tier should be...
This paper considers the problem of improving localization accuracy in wireless networks by adjusting the path-loss model exponents depending on public road network information. Using the RSS high variations for further positioning accuracy improvement is also considered. First, localization depending on path-loss model is discussed. Second, the road network information is used to improve the accuracy...
A growing number of mobile phone applications utilize physical location to express the context of information. Most of these location-based applications assume GPS capabilities. Unfortunately, GPS incurs an unacceptable energy cost that can reduce the phone's battery life to less than nine hours. Alternate localization technologies, based on WiFi or GSM, improve battery life at the expense of localization...
Location determination in GSM network is the major challenging issue due to the several complexities on both software and hardware side. The location of mobile node is always an important issue in GSM network because location based services to facilitate the user is gaining popularity in public. An error corrected rectangulation method based on intensity (ECRMI) is proposed that estimate the location...
This study presents a metropolitan-scale location system using FM radio. FM is a wider-covered and longer-lived infrastructure and originally designed to listen for broadcasting information. Although FM towers have existed for a long time and recent mobile devices have already contained a low-cost FM receiving function, using FM signal strength for positioning has not been well explored. Our system...
