Abstract

As system for locating a network node may be implemented as a static network device for determining location of a mobile node. The system includes a transceiver for receiving a device identifier over a public network from the mobile node, the device identifier based on a user-configurable parameter and a non-user-configurable parameter of the mobile node, and a processor coupled to the transceiver and to memory containing executable code. When executed, the code effects method steps for: accessing, in response to the transceiver receiving the device identifier, a database of authorized device identifiers corresponding to known mobile nodes, establishing, in response to the device identifier matching one of the authorized device identifiers, a secure private network with the mobile node, and communicating with two additional static network devices, the three static network devices implementing triangulation to determine a location of the mobile node.

Claims

receiving a device identifier over a public network from the mobile node, the device identifier being based on a combination of at least one user-configurable parameter and at least one non-user-configurable parameter of the mobile node;

accessing a database of authorized identifiers corresponding to known mobile nodes;

establishing, in response to the device identifier matching one of the authorized identifiers, a secure private network (SPN) with the mobile node; and

using triangulation to determine a location of the mobile node.

2. The method of claim 1, further comprising sending the location information to the mobile node via the SPN.

3. The method of claim 1, further comprising supplementing the triangulation with data from a Global Positioning Satellite (GPS) system to determine the location of the mobile node.

4. A method, at a mobile node, for obtaining location information of the mobile node, comprising:

determining three static nodes closest to the mobile node via a public network;

sending a device identifier to at least one of the three static nodes, the device identifier being based on a combination of at least one user-configurable parameter and at least one non-user-configurable parameter of the mobile node;

estavlishing, in response to the at least one of the three static nodes authenticating the device identifier, a secure private network (SPN) with the three static nodes, the three static nodes implementing triangulation to determine a location of the mobile node; and

receiving information regarding the location of the mobile node from the at least one of the three static nodes via the SPN.

5. The method of claim 4, wherein the at least one non-user-configurable parameter comprises at least one of CPU ID, CPU model, CPU manufacturer, and CPU voltage for the mobile node.

6. The method of claim 4, wherein the at least one non-user-configurable parameter is based on a carbon degradation characteristic of a computer chip of the mobile node.
