Localizing Tags Using Mobile Infrastructure,xpensive tags. The data collected at various positions are combined by a simple “l(fā)eapfrog” procedure, with constrained optimization to obtain better accuracy. Our system achieves about one foot (0.3 meter) accuracy with 90% confidence in indoor environments.

Bootstrapping a Location Service Through Geocoded Postal Addresses,n service that contains the MAC addresses and geographic position of wireless LAN access points enables positioning services for WLAN devices and location-aware networking protocols. This work thus compares the accuracy of access point position estimates obtained based on RF signal strengths reading

LifeTag: WiFi-Based Continuous Location Logging for Life Pattern Analysis,, and life pattern analysis. GPS is one way of logging, but it is unable to track movements indoors, and hence cannot track peoplefs ordinary activities. We propose a WiFi-based location detection technology for location logging. It detects a device’s location from received WiFi beacon signals. It w
