Abstract

A wireless communication device includes an antenna coupled to a wireless communications transceiver, a processor, and a vehicle safety application. When the vehicle safety application is executed, it causes the processor to cause the wireless communication device to join a basic service set through the antenna and wireless communications transceiver. The application also causes the processor to determine a location of the wireless communication device, receive location information indicative of a location of another wireless communication device in the basic service set, and generate an alert based on the determined location and the received location information.

Claims

1. A wireless communication device, comprising:

an antenna coupled to a wireless communications transceiver;

a processor; and

a vehicle safety application that, when executed, causes the processor to;

cause the wireless communication device to join a basic service set through the antenna and wireless communications transceiver;

determine a location of the wireless communication device;

receive location information indicative of a location of another wireless communication device in the basic service set; and

generate an alert based on the determined location and the received location information.

2. The system of claim 1 further comprising a GPS transceiver, wherein the vehicle safety application, when executed, further causes the processor to turn on the wireless communications transceiver and the GPS transceiver.

3. The system of claim 1 wherein the vehicle safety application, when executed, further causes the processor to acquire identification information of a person or vehicle associated with the wireless communication device.

4. The system of claim 1 wherein the vehicle safety application, when executed, further causes the processor to broadcast the location of the wireless communication device to another wireless communication device in the basic service set.

5. The system of claim 1 wherein the vehicle safety application, when executed, further causes the processor to create an basic service set if no basic service set exists in the proximity of the wireless communication device.

6. The system of claim 1 wherein the alert comprises a visual alert or an audio alert.

7. The system of claim 1 wherein the alert indicates a traffic condition, a likely collision condition, or a traffic signal status.

8. The system of claim 1 wherein the wireless communications transceiver comprises an 802.11p transceiver and the basic service set comprises an 802.11p basic service set.

9. A method, comprising:

joining, by a wireless communication device, a basic service set;

determining a location of the wireless communication device;

receiving location information indicative of a location of another wireless communication device in the basic service set; and

generating an alert based on the determined location and the received location information.

10. The method of claim 9 further comprising turning on a wireless communications transceiver of the wireless communication device.

11. The method of claim 9 further comprising acquiring identification information of a person or vehicle associated with the wireless communication device.

12. The method of claim 9 further comprising broadcasting the location of the wireless communication device to another wireless communication device in the basic service set.

13. The method of claim 9 further comprising creating a basic service set if no basic service set exists in the proximity of the wireless communication device.

14. The method of claim 9 wherein the alert indicates a traffic condition, a likely collision condition, or a traffic signal status.

15. The method of claim 9 wherein the basic service set comprises an 802.11p basic service set.

16. A machine-readable storage device containing machine-readable instructions that, when executed by a hardware processor of a wireless communication device, cause the hardware processor to:

cause the wireless communication device to join a basic service set;

determine a location of the wireless communication device;

receive location information indicative of a location of another wireless communication device in the basic service set; and

generate an alert based on the determined location and the received location information.

17. The machine-readable storage device of claim 16 wherein the instructions, when executed, further cause the processor to turn on a wireless communications transceiver and a GPS transceiver.

18. The machine-readable storage device of claim 16 wherein the instructions, when executed, further cause the processor to acquire identification information of a person or vehicle associated with the wireless communication device.

19. The machine-readable storage device of claim 16 wherein the instructions, when executed, further cause the processor to broadcast the location of the wireless communication device to another wireless communication device in the basic service set.

20. The machine-readable storage device of claim 16 wherein the instructions, when executed, further cause the processor to create a basic service set if no basic service set exists in the proximity of the wireless communication device.
