Abstract

A system and method a bi-directional wireless information system includes a plurality of sensor nodes spaced along a path of travel of an object, each of the sensor nodes corresponding to a specified location along the path of travel. The system also includes a transceiver associated with the object, the transceiver configured to communicate with the plurality of sensor nodes, such that a location of the object is determinable based on wireless communication between the transceiver and the plurality of sensor nodes. A central database included in the system is configured to receive the location of the object from at least one of the transceiver and the plurality of sensor nodes, receive object-specific data from at least one of the transceiver and the plurality of sensor nodes, and transmit location-specific data to the transceiver.

Claims

1. A bi-directional wireless information system comprising:

a plurality of sensor nodes spaced along a path of travel of an object, each of the sensor nodes corresponding to a specified location along the path of travel;

a transceiver associated with the object, the transceiver configured to communicate with the plurality of sensor nodes, such that a location of the object is determinable based on wireless communication between the transceiver and the plurality of sensor nodes; and

a central database configured to;

receive the location of the object from at least one of the transceiver and the plurality of sensor nodes;

receive object-specific data from at least one of the transceiver and the plurality of sensor nodes; and

transmit location-specific data to the transceiver.

2. The bi-directional wireless information system of claim 1 wherein the plurality of sensor nodes are further configured to relay the location-specific data to at least one of the central database and the object.

3. The bi-directional wireless information system of claim 1 wherein the plurality of sensor nodes further comprise one of RFID sensors and wireless sensors.

4. The bi-directional wireless information system of claim 1 wherein the transceiver further comprises a remote device;

and

wherein the remote device is incorporated within one of a laptop computer, a PDA, a cellular phone, and a wireless handset.

5. The bi-directional wireless information system of claim 1 wherein the plurality of sensor nodes further comprise a multi-hop wireless network configured with a connectionless scheduling protocol.

6. The bi-directional wireless information system of claim 1 wherein the object further comprises one of a vehicle, a handheld wireless device, and a human being.

7. The bi-directional wireless information system of claim 1 wherein location-specific data further comprises at least one of geographical position data, weather data, traffic data, road condition data, point-of-interest data, and parking lot data.

8. The bi-directional wireless information system of claim 1 wherein object-specific data further comprises at least one of vehicle-related data and biometric driver-related data.

9. The bi-directional wireless information system of claim 8 wherein the central database is further configured to transmit vehicle control commands corresponding to the object-specific data.

10. The bi-directional wireless information system of claim 8 wherein vehicle-related data further comprises at least one of diagnostic data, inventory data, and door status data.

11. A method for bi-directional wireless transmission of information between an object and a central data system comprising the steps of:

arranging a network of wireless sensors along a pathway;

associating each sensor of the network of wireless sensors with a respective position along the pathway;

wirelessly transmitting an object location to a central data system when the object moves along the pathway, the object location corresponding to the respective positions of the wireless sensors;

accessing location-specific data from the central data system, the location-specific data corresponding to the object location; and

wirelessly transmitting the location-specific data from the central data system to the object.

12. The method of claim 11 further comprising the steps of:

wirelessly transmitting object-specific data from the object to the central data system;

generating vehicle control commands based on the object-specific data; and

wirelessly transmitting the vehicle control commands from the central data system to the object.

13. The method of claim 12 further comprising the step of wirelessly transmitting at least one of vehicle data and biometric driver data from the object to the central data system.

14. The method of claim 11 further comprising the step of wirelessly transmitting an identifier associated with one sensor of the network of sensors when the object passes the sensor on the pathway.

15. The method of claim 11 further comprising the step of wirelessly transmitting at least one of geographical position data, weather data, traffic data, point-of-interest data, and parking lot data from the central data system to the object.

16. A wireless roadway information system comprising:

a network of sensors positioned along a roadway, each of the sensors corresponding to a specified location;

a processing unit disposed within a vehicle and comprising;

a transceiver configured to wirelessly communicate with the network of sensors, such that a location of the vehicle is determinable based on wireless communication between the transceiver and one of the network of sensors; and

a plurality of vehicle data sensors configured to acquire vehicle-specific information; and

a central database located remotely from the network of sensors and the transceiver, the central database configured to;

receive a wireless signal from one of the transceiver and a sensor in the network of sensors, the wireless signal including a location of the vehicle and vehicle-specific information;

determine location-specific information based on the location of the vehicle;

determine vehicle control commands based on the vehicle-specific information; and

transmit the location-specific information and vehicle control commands to the transceiver.

17. The wireless roadway information system of claim 16 wherein the network of sensors further comprises a multi-hop wireless sensor network configured with a connectionless scheduling protocol.

18. The wireless roadway information system of claim 16 wherein the network of sensors further comprises one of RFID tags and wireless access points.

19. The wireless roadway information system of claim 16 wherein the location-specific information further comprises at least one of weather information, traffic information, point-of-interest information, and parking lot information.

20. The wireless roadway information system of claim 16 wherein vehicle-specific information further comprises at least one of vehicle diagnostic information, vehicle inventory information, and door status information.
