Abstract

A location-based content-centric networking method for location-based content is provided. The location-based content-centric networking method may include: naming location-based content in such a manner that the name given to the location-based content includes a hierarchical prefix corresponding to information contained in the location-based content; and forwarding the location-based content based on prefix information of the location-based content.

Claims

1. A location-based content-centric networking method for a location-based content, comprising:

naming the location-based content including assigning a name to the location-based content, wherein the name includes a hierarchical prefix corresponding to information contained in the location-based content;

caching the location-based content;

receiving a user'"'"'s interest for requesting the location-based content; and

forwarding the location-based content based on prefix information of the location-based content,

wherein the forwarding the location-based content comprises transmitting the location-based content to neighboring nodes so as to advertise the location-based content, and

wherein the caching the location-based content comprises determining, at a node that receives the location-based content, whether to cache the advertised location-based content, based on a distance between the node and the location at which the location-based content is created

wherein in the determining whether to cache the advertised location-based content, a cache probability is decreased with an increase in the distance.

2. The location-based content-centric networking method of claim 1, wherein the naming the location-based content comprises defining a first prefix at a very beginning of the name in order to distinguish the location-based content from other content by means of a longest prefix matching (LPM) scheme.

3. The location-based content-centric networking method of claim 1, wherein the naming the location-based content comprises defining a second prefix to classify a user'"'"'s intention.

4. The location-based content-centric networking method of claim 3, wherein the user'"'"'s intention is to search or to advertise content.

5. The location-based content-centric networking method of claim 1, wherein the naming the location-based content comprises defining a third prefix to classify a type of the location-based content.

6. The location-based content-centric networking method of claim 1, wherein the naming the location-based content comprises defining a fourth prefix including location information of the location-based content.

7. The location-based content-centric networking method of claim 1, wherein the naming the location-based content comprises defining a fifth prefix including a context name as a target of the location-based content.

8. The location-based content-centric networking method of claim 1, wherein the user'"'"'s interest includes an identifier of the location-based content requested by a user.

9. The location-based content-centric networking method of claim 1, further comprising transmitting the user'"'"'s interest to the neighboring nodes so as to acquire the location-based content requested by the user.

10. The location-based content-centric networking method of claim 9, wherein the forwarding the location-based content utilizes location information about where the location-based content is created and location information of a node that receives the user'"'"'s interest or the location-based content.

11. The location-based content-centric networking method of claim 10, the forwarding the location-based content to the neighboring nodes comprises advertising created or updated location-based content to nodes within a predetermined range of area according to predefined rules.

12. The location-based content-centric networking method of claim 11, wherein a prefix which indicates advertisement of the location-based content is previously registered in a pending interest table (PIT).

13. The location-based content-centric networking method of claim 11, wherein a geographical range within which the location-based content is advertised is determined by utilizing information about a distance between the location at which the location-based content is created and the location of the node.

14. The location-based content-centric networking method of claim 9, wherein the forwarding the location-based content comprises forwarding the user'"'"'s interest for the location-based content using location information contained in the location-based content.

15. The location-based content-centric networking method of claim 14, further comprising:

registering in forwarding information base (FIB) prefix information which confirms that the location-based content is location-based content, so as to invoke a function to perform location-based forwarding with respect to the prefix information.

16. The location-based content-centric networking method of claim 9, wherein the caching the location-based content comprises caching data in response to the user'"'"'s interest, wherein a probability of cache replication being executed is set to be reduced with an increase in a distance between a node that receives the data and a target location of location-based content included in the data.

17. The location-based content-centric networking method of claim 9, wherein the caching the location-based content comprises caching data in response to the user'"'"'s interest, wherein a probability of cache replacement being executed is set to be increased with an increase in a distance between a node that receives the data and a location of the location-based content stored in the cache.
