Claims18
A method of tracking and updating a location of a movable electronic device that includes a wireless interface for interaction with portable wireless mobile devices of users, the method comprising:
- reducing an update interval of time for the movable electronic device based on a reduced time-average interval between observed node location changes;
- and
- only when the update interval of time has elapsed, (i) opportunistically interrogating a portable wireless mobile device of a user, via the wireless interface, for local GPS coordinates of the portable wireless mobile device only upon occurrence of a proximity event when the portable wireless mobile device is moved into proximity with the movable electronic device, and (ii) electronically communicating the local GPS coordinates to a location server as the location of the movable electronic device.
A method of tracking and updating a location of a movable electronic device that includes a wireless interface for interaction with portable wireless mobile devices of users, the method comprising:
- increasing an update interval of time for the movable electronic device based on an increased time-average interval between observed node location changes;
- and
- only when the update interval of time has elapsed, (i) opportunistically interrogating a portable wireless mobile device of a user, via the wireless interface, for local GPS coordinates of the portable wireless mobile device only upon occurrence of a proximity event when the portable wireless mobile device is moved into proximity with the movable electronic device, and (ii) electronically communicating the local GPS coordinates to a location server as the location of the movable electronic device.
