Trilateration processing of abnormal location data

A mobile computing device comprising:

• a processor;
• a memory;
• and
• trilateration logic executed via the processor to:
• receive location data for the mobile computing device, the location data determined, at least in part, from Wi-Fi data received from one or more other devices;
• update a threshold value from a first value to a second value based on a distance between a calculated location of the mobile computing device and the received location data;
• calculate a revised location of the mobile computing device using the received location data and a plurality of stored location data, wherein calculating the revised location includes applying a reduced reliability weight to one of the location data values if its distance from the calculated location of the mobile computing device is greater than a first distance value and less the threshold value;
• and
• change the threshold value to the first value.

A machine-readable storage medium having computer executable instructions stored thereon that, when executed, cause a processor to perform a method comprising:

• receiving location data for a mobile computing device, the location data determined, at least in part, from Wi-Fi data received from one or more other devices;
• updating a threshold value from a first value to a second value based on a distance between a calculated location of the mobile computing device and the received location data;
• calculating a revised location of the mobile computing device using the received location data and a plurality of stored location data, wherein calculating the revised location includes applying a reduced reliability weight to one of the location data values if its distance from the calculated location of the mobile computing device is greater than a first distance value and less the threshold value;
• and
• changing the threshold value to the first value.
