Claim:
1. A method comprising: providing a perimeter-anchoring device and a constrained device, with each of the perimeter-anchoring and constrained devices: receiving, from the location determination module of the constrained device, the current geographic location of the constrained device; monitoring, by an environmental factor module, a first environmental factor, based at least in part upon the current geographic location of at least one of the following: the constrained device and the perimeter-anchoring device; receiving, from the location determination module of the perimeter-anchoring device, the current geographic location of the perimeter-anchoring device; determining, by a perimeter module on an on-going basis, a geographic area surrounding the perimeter-anchoring device, based at least in part upon the first environmental factor, with the geographic area being bounded by a perimeter so that the area and perimeter will dynamically move with any movements of the current geographic location of the perimeter-anchoring device; determining, by a comparison module, whether the constrained device is located outside of the perimeter, based at least in part upon the current geographic location of the constrained device and the current geographic location of the perimeter-anchoring device; and on condition that the constrained device is located outside of the perimeter, performing, by an alerting module, a responsive action.
