Abstract

Systems, methods, media, and devices for providing cooperation among digital processing devices in wireless networks are provided. In some embodiments, methods for moving a connection from one point of access to another point of access are provided, sending a request for information from a first mobile node to at least one other node, wherein the request for information contains first information identifying at least one point of access; receiving a response containing second information identifying at least one point of access from the at least one other node; and establishing a connection between the first mobile node and a point of access identified in the second information. In some embodiments, devices that can move a connection from one point of access to another point of access are provided.

Claims

1. A method for facilitating moving a connection from one point of access to another point of access, comprising:

receiving a request for information from a first mobile node at at least one other mobile node, wherein the request for information contains first information identifying at least one point of access including a basic service set identifier (BSSID);

determining at the at least one other mobile node second information identifying at least one other point of access based at least in part on the request; and

sending a response containing the second information identifying the at least one other point of access and statistics of the at least one other point of access.

2. The method of claim 1, wherein the statistics of the at least one other point of access comprise throughput capability of the at least one other point of access.

3. The method of claim 1, wherein the information identifying at least one of the at least one point of access from the first information and the at least one other point of access from the second information includes a Media Access Control address.

4. The method of claim 1, wherein the information identifying at least one of the at least one point of access from the first information and the at least one other point of access from the second information includes at least one of a channel and a subnet identifier.

5. The method of claim 1, wherein at least one of the request and the response are multicast packets.

6. The method of claim 1, wherein at least one of the first mobile node and the at least one other mobile node is in ad-hoc mode.

7. The method of claim 1, wherein the first information and the second information each contain a list and wherein the lists are of the same format.

8. The method of claim 1, further comprising storing the second information in a cache.

9. A method for moving a connection from one point of access to another point of access, comprising:

sending a request for information from a first mobile node to at least one other node, wherein the request for information contains first information identifying at least one point of access including a basic service set identifier (BSSID);

receiving, from the at least one other node, a response including second information identifying at least one other point of access corresponding to the BSSID;

sending a request for a Media Access Control (MAC) address to the identified at least one other point of access;

receiving a response containing the MAC address of the identified at least one other point of access; and

establishing a connection between the first mobile node and the identified at least one other point of access using the MAC address.

10. The method of claim 9, wherein the first mobile node and the at least one other point of access are in different subnets before the establishing of the connection.

11. The method of claim 9, wherein the receiving a response identifying at least one other point of access further comprises receiving statistics of the at least one other point of access.

12. The method of claim 11, wherein the statistics of the at least one other point of access comprise throughput capability of the at least one other point of access.

13. The method of claim 9, wherein the receiving a response identifying at least one other access point further comprises receiving statistics of the at least one other point of access.

14. The device of claim 13, wherein the statistics of the at least one other point of access comprise throughput capability of the point of access.

15. A device that can facilitate moving a connection from one point of access to another point of access, comprising:

an interface in communication with a network;

a memory; and

a processor in communication with the memory and the interface;

wherein the processor;

receives a request for information from a first mobile node, wherein the request for information contains first information identifying at least one point of access including a basic service set identifier (BSSID);

determines second information identifying at least one other point of access based at least in part on the request; and

sends a response containing the second information identifying the at least one other point of access and statistics of the at least one other point of access.

16. The device of claim 15, wherein the statistics of the at least one other point of access comprise throughput capability of the at least one other point of access.

17. The device of claim 15, wherein the information identifying at least one of the at least one point of access from the first information and the at least one other point of access from the second information includes a Media Access Control address.

18. The device of claim 15, wherein the information identifying at least one of the at least one point of access from the first information and the at least one other point of access from the second information includes at least one of a channel and a subnet identifier.

19. The device of claim 15, wherein at least one of the request and the response are multicast packets.

20. The device of claim 15, wherein at least one of the first mobile node and the at least one other mobile node is in ad-hoc mode.

21. The device of claim 15, wherein the first information and the second information each contain a list and wherein the lists are of the same format.

22. The device of claim 15, further comprising storing the at least one second entry in a cache.

23. A device that can facilitate moving a connection from one point of access to another point of access, comprising:

an interface in communication with a network;

a memory; and

a processor in communication with the memory and the interface;

wherein the processor;

sends a request for information to at least one other node, wherein the request for information contains first information identifying at least one point of access including a basic service set identifier (BSSID);

receives, from the at least one other node, a response including second information identifying at least one other point of access corresponding to the BSSID;

sends a request for a Media Access Control (MAC) address to the identified at least one other point of access;

receives a response containing the MAC address of the identified at least one other point of access; and

establishes a connection with the identified at least one other point of access using the MAC address.

24. The device of claim 23, wherein the at least one other point of access is in a different subnet before the establishing of the connection.
