Abstract
Embodiments of the invention address how trilateration processes, used to obtain a location of a mobile computing device, are affected by physical placement and sub-optimal selection of peer devices (PDs). 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 selectively utilize abnormal location poll data when executing location determination processes. Embodiments of the invention further enhance trilateration processes by utilizing dampening values for calculated location poll data.
