Abstract

An intelligent real-time distributed traffic sampling and navigation system comprising intelligent clients having location based service capability servers, the system provides sampling navigation information by the one or more clients and transmitting the navigation information from the one or more clients to the one or more servers and generating an update information by the one or more servers with the navigation information.

Claims

1. An intelligent real-time distributed traffic sampling and navigation system comprising one or more clients having location based service capability and one or more servers, the system comprises:

sampling a navigation information by the one or more clients;

transmitting the navigation information from the one or more clients to the one or more servers; and

generating an update information by the one or more servers with the navigation information.

2. The system as claimed in claim 1 further comprising providing controls by the one or more servers, or by the one or more clients, or by the combination thereof, to the one or more clients comprising:

selecting a sample size of the one or more clients by the one or more servers; and

setting a sample rate of the one or more clients by the one or more servers, or by the one or more clients, or the combination thereof.

3. The system as claimed in claim 1 wherein sampling the navigation information by the one or more clients comprises sampling navigation information from a partial distribution of the clients.

4. The system as claimed in claim 1 wherein transmitting the navigation information from the one or more clients to the one or more servers comprises transmitting navigation information from a partial distribution of the one or more client to the or more servers.

5. The system as claimed in claim 1 wherein generating the update information by the one or more servers with the navigation information comprises validating results by the one or more servers of the navigation information.

6. An intelligent real-time distributed traffic sampling and navigation system comprising one or more clients having location based service capability and one or more servers comprises:

providing controls by a distribution of the servers to a distribution of the clients;

gathering navigation information from the distribution of the clients;

transmitting over a communication path the navigation information from the distribution of the clients to the distribution of the servers;

generating an update by the distribution of servers with the navigation information; and

sending the update from the distribution of the servers to the distribution of the clients.

7. The system as claimed in claim 6 further comprising forming a communication path within the distribution of the servers.

8. The system as claimed in claim 6 wherein generating the update by the distribution of servers comprises generating the update with the navigation information using distributive processing by the one or more servers.

9. The system as claimed in claim 6 wherein generating the update by the server with the navigation information comprises transmitting past navigation information samples stored by the one or more clients to the one or more servers.

10. The system as claimed in claim 6 wherein generating the update by the distribution of servers with the navigation information comprises extrapolating by the one or more servers an update for a no server access area with navigation information samples before the no server access area, or after the no server access area, or a combination thereof.

11. An intelligent real-time distributed traffic sampling and navigation system comprising one or more clients having location based service capability and one or more servers comprises:

a sampling circuitry within each client for sampling navigation information by the client;

a transmission circuitry within each client for transmitting navigation information from the client to the one or more servers, or to the one or more clients, or to a combination thereof; and

a generation circuitry within each server for generating an update with the navigation information received from the one or more clients.

12. The system as claimed in claim 11 further comprising a server control circuitry within each of the servers and a client control circuitry in each of the clients comprising:

a server selection circuitry within each server to select a sample size of the one or more clients;

a client selection circuitry within each client to select the sample size;

a server sample rate circuitry within each server to select sample rate of the one or more clients; and

a client sample rate circuitry within each of the client to select sample rate.

13. The system as claimed in claim 11 further comprising a gathering circuitry within each server for selectively gathering navigation information from the one or more clients.

14. The system as claimed in claim 11 wherein the sampling circuitry within each client further comprises a transmission rate circuitry for controlling transmission of the navigation information to the one or more servers.

15. The system as claimed in claim 11 wherein the generation circuitry within each server further comprises a validation circuitry for validating the navigation information from the one or more clients.

16. The system as claimed in claim 11 further comprising a server communication circuitry within each server for controlling transmission of navigation information between the one or more servers.

17. The system as claimed in claim 16 wherein the update generated by the server to the one or more clients comprises travel routes generated by the one or more servers.

18. The system as claimed in claim 16 wherein the generation circuitry within each server further comprises a partition circuitry for distributive processing of navigation information from the one or more clients.

19. The system as claimed in claim 16 wherein the update generated by the one or more servers comprises navigation information stored by the client sent to the server.

20. The system as claimed in claim 16 wherein generation circuitry further comprises an analysis circuitry for extrapolating the update with the navigation information from the one or more clients before the no server access area, or after the no service access area, or a combination thereof
