Abstract

Methods, devices, and systems for information dissemination in a wireless communication system are provided. In one embodiment, a method of information dissemination in a wireless communication system comprises generating an information advertisement signal by a wireless device acting as a distributor node, wherein said information advertisement signal identifies information available from said wireless device; sending said information advertisement signal by said wireless device to a propagator node using an access point, wherein said wireless device is connected to said access point, and said access point is connected to said propagator node; receiving a selection request signal by said wireless device from said propagator node using said access point, wherein said selection request signal identifies information requested by a selector node via said propagator node; and sending an information datagram by said wireless device towards said selector node via said propagator node using said access point, wherein said information datagram contains all or a portion of said information.

Claims

1. A method of information dissemination in a wireless communication system, comprising:

generating an information advertisement signal by a wireless device acting as a distributor node, wherein said information advertisement signal identifies information available from said wireless device;

sending said information advertisement signal by said wireless device to a propagator node using an access point, wherein said wireless device is connected to said access point, and said access point is connected to said propagator node;

receiving a selection request signal by said wireless device from said propagator node using said access point, wherein said selection request signal identifies information requested by a selector node via said propagator node; and

sending an information datagram by said wireless device towards said selector node via said propagator node using said access point, wherein said information datagram contains all or a portion of said information.

2. The method of claim 1, wherein said sending of said information advertisement signal by said wireless device to a propagator node using an access point includes:

sending said information advertisement signal over a neighbor interface module of said wireless device, wherein said neighbor interface module is associated with said propagator node;

wherein said receiving of a selection request signal by said wireless device from said propagator node using said access point includes;

receiving said selection request signal over a neighbor interface module of said wireless device, wherein said neighbor interface module is associated with said propagator node; and

wherein said sending of an information datagram by said wireless device towards said selector node via said propagator node using said access point includes;

sending said information datagram over a neighbor interface module of said wireless device, wherein said neighbor interface module is associated with said propagator node.

3. The method of claim 1, wherein said sending of an information datagram by said wireless device towards said selector node via said propagator node using said access point further comprising:

segmenting said information into one or more portions of said information;

constructing one or more of said information datagrams, wherein each information datagram includes an information tag, said portion of said information, or both.

4. The method of claim 3, wherein said information tag includes an information object identifier, wherein said information object identifier identifies said portion of said information.

5. The method of claim 1, wherein said information advertisement signal includes a distributor tag.

6. The method of claim 1, wherein said selection request signal includes a selection tag.

7. The method of claim 1, wherein said selection request signal, said information datagram, or both includes a session initiation protocol (“

SIP”

) signaling message.

8. The method of claim 1, wherein said selection request signal, said information datagram, or both includes a hypertext transfer protocol (“

HTTP”

) signaling message.

9. The method of claim 1, wherein said selection request signal, said information advertisement signal, said information datagram, or any combination thereof is cryptographically signed.

10. A method of information dissemination in a wireless communication system, comprising:

generating a selection request signal by a wireless device acting as a selector node, wherein said selection request signal identifies information requested by said wireless device;

sending said selection request signal by said wireless device to a propagator node using an access point, wherein said wireless device is connected to said access point, and said access point is connected to said propagator node;

receiving an information datagram by said wireless device from said propagator node using said access point, wherein said information datagram contains all or a portion of said information.

11. The method of claim 10, wherein said sending of said selection request signal by said wireless device to a propagator node using an access point includes:

sending said selection request signal over a neighbor interface module of said wireless device, wherein said neighbor interface module is associated with said propagator node; and

wherein said receiving an information datagram by said wireless device from said propagator node using said access point includes;

receiving said information datagram over a neighbor interface module of said wireless device, wherein said neighbor interface module is associated with said propagator node.

12. The method of claim 10, wherein said selection request signal includes a selection tag.

13. The method of claim 10, wherein said information datagram includes an information tag, wherein said information tag includes an information object identifier, wherein said information object identifier identifies said portion of said information.

14. The method of claim 10, wherein said selection request signal, said information datagram, or both includes a session initiation protocol (“

SIP”

) signaling message.

15. The method of claim 10, wherein said selection request signal, said information datagram, or both includes a hypertext transfer protocol (“

HTTP”

) signaling message.

16. The method of claim 10, wherein said selection request signal, said information datagram, or both is cryptographically signed.

17. A wireless device acting as a distributor node in a wireless communication system, comprising:

a processor coupled to a memory containing processor-executable instructions, wherein said processor is capable to;

generate an information advertisement signal, wherein said information advertisement signal identifies information available from the wireless device;

send said information advertisement signal to a propagator node using an access point, wherein the wireless device is connected to said access point, and said access point is connected to said propagator node;

receive a selection request signal from said propagator node using said access point, wherein said selection request signal identifies information requested by a selector node via said propagator node; and

send an information datagram towards said selector node via said propagator node using said access point, wherein said information datagram contains all or a portion of said information.

18. A computer program product for information dissemination in a wireless communication system, comprising:

a computer-readable medium comprising;

a first set of codes to generate an information advertisement signal by the wireless device acting as a distributor node, wherein said information advertisement signal identifies information available from said wireless device;

a second set of codes to send said information advertisement signal by the wireless device to a propagator node using an access point, wherein the wireless device is connected to said access point, and said access point is connected to said propagator node;

a third set of codes to receive a selection request signal by the wireless device from said propagator node using said access point, wherein said selection request signal identifies information requested by a selector node via said propagator node; and

a fourth set of codes to send an information datagram by the wireless device towards said selector node via said propagator node using said access point, wherein said information datagram contains all or a portion of said information.

19. A wireless device acting as a selector node in a wireless communication system, comprising:

a processor coupled to a memory containing processor-executable instructions, wherein said processor is capable to;
