WI-FI Tracker: an Organization WI-FI Tracking System

Abstract

Path and location tracking are one of the main interesting and fast growing applications in Mobile and Wireless Communications. The developments of such systems have interested many research, industrial and government bodies with solutions that range in scale and accuracy. The GPS system, Cell based tracking in cellular networks are just few examples. However such technologies have their limitations. GPS does not work inside buildings, cellular systems are not owned by organizations and only work with mobile phones and have high subscriptionfees.The prototype implemented in this paper illustrates a simple path and location tracking system within an organization based on its available infrastructure Wi-Fi network. By using signal strength and histories ofaccess points used by a mobile node we can provide an approximate determination of the location in the services area and also the moved path of the mobile node. In our work we use web services for location services to enable queries and manage the path and location of the mobile node. The system has shown impressive results that enable software developers to provide useful types of location based service applications for organizational tasks.

Bluetooth Navigation System Using WI-FI Access Points

“…Being global in nature, GPS gives the latitude and longitude details of a GPS receiver but the kind of tracking that we are talking about is in a localized area comprising of both indoor and outdoor locations. Systems relying on cellular networks [2] have to be owned and administered by the service provider and not the organization and may need subscription fee as well. The systems that completely depend on Wi-Fi consider either laptops or mobile phones as their mobile nodes to track down the owners of these devices.…”

“…A mere connection of a person with an access point can help us to locate him by finding out the location of the access point on the basis of its MAC ID but this would be in a range of around 30 meters (the range of a normal Wi-Fi access point). So, most of these systems are based on Received Signal Strength Indicator (RSSI) [2] [10] and Signature Matching [3] or Fingerprinting [4]. The former are based on propagation models that relate the signal strength directly to the distance from the Wi-Fi access point (AP) using, for example the Friss formula [5] and can work for stagnant or slow moving assets.…”

Real-Time Wireless Location and Tracking System with Motion Pattern Detection

“…Another advantage of this technology is the possibility of tracking an object by using a single access point, though the precision will weaken due to the lack of signal triangulation. Because of its technical details, the impact of issues such as occlusion and signals loss is reduced to a residual level especially in environments, which do not have high concentration of metallic materials (Mingkhwan, 2006). Bluetooth is a wireless protocol available on any modern mobile equipment, allowing data exchange between multiple devices.…”

BUSINESS INTELLIGENCE THROUGH REAL-TIME TRACKING - Using a Location System Towards Behaviour Pattern Extraction

“…With only one access point the system's precision may not be very high but there is no need for triangulation. Occlusion problems and signals losses, with the use of this technique will be reduced to a residual level in both open spaces and indoors -considering that indoor spaces do not have significant metal structures within the walls) (Mingkhwan, 2006).…”
