Apparatus and method for processing contents using routing table

A method of updating a routing table in each node in a mobile ad hoc network environment, comprising:

• a certain node receiving a specific path for which interest information of a user of a destination node and an effectiveness value thereof are set;
• calculating an effectiveness value based on both the interest information of the user of the destination node and interest information of a user of the certain node;
• setting the calculated effectiveness value in the specific path and adding the specific path to a routing table included in the certain node when the specific path is not present in the routing table;
• and
• updating paths included in the routing table by comparing the calculated effectiveness value with effectiveness values of paths included in the routing table when the specific path is present in the routing table.

A method of processing content, the method processing a content reply message using a routing table for storing interest information of users and effectiveness values for respective paths, comprising:

• when the content reply message is received, determining whether to cache content by comparing content characteristics of the content reply message with interest information of a user set in a routing table of a node which received the content reply message;
• when a destination node of the content reply message is the node which received the content reply message after determining whether to cache the content, notifying an application that requested content has been received;
• and
• when the destination node is not the node which received the content reply message, selecting a path having a highest effectiveness value from among paths having a destination node identical to that included in the received content reply message by searching the routing table, and then sending the content reply message through the selected path.
