3GPE: An Energy Efficient Probabilistic Fingerprint-Assisted Localization in Indoor Wi-Fi Areas

Provided by: Institute of Electrical & Electronic Engineers Topic: Mobility Date Added: May 2012 Format: PDF
As the most competitive and cost-efficient localization technology, the map-aided fingerprinting-assisted positioning has drawn a large body of attentions during the past decade. There are normally two phases, the off-line and on-line phases, and the construction of radio map in the off-line phase will significantly influence the location accuracy in the on-line phase. However, the radio map which describes the mapping relationship between the physical positions of the Reference Points (RPs) and the recorded Radio Signal Strength (RSS) or Signal to Noise Ratio (SNR) always involves the cumbersome collection work.
