Abstract
Official abstract text for this publication.
Embodiments of the invention address how trilateration processes are affected by physical placement and sub-optimal selection of peer devices (PDs) used to obtain a location of a mobile computing device. Embodiments of the invention describe processes for selecting nearest PDs over further PDs, as received signal strength indicator (RSSI) measurements are more reliable—i.e., said “nearest PDs” provide more accurate distance measurements while improving the probability of finding more intersection points. Embodiments of the invention further describe selecting a physical spread of PDs to help increase the number of intersection points while helping distinction/resolution of the location of the mobile device in both the ‘x’ (longitude) and the ‘y’ (latitude) directions. Embodiments of the invention further enhance trilateration processes by utilizing dampening values for calculated location poll data.
First claim
Opening claim text (preview).
The invention claimed is: 1. A non-transitory machine-readable storage medium having computer executable instructions stored thereon that, when executed, cause a processor to perform a method comprising: receiving Wi-Fi data at a mobile computing device from a plurality of peer devices; determining a distance from the mobile computing device to each of the plurality of peer devices, including, when the mobile computing device is stationary, reducing reliability of distance calcu…
