Abstract
Provided is a congestion control method for controlling message flooding between nodes in response to situation information in information centric network environment with delay tolerant networking, and a recording medium and a device for performing the same. The congestion control method includes, when a first node contacts a second node, exchanging information associated with stored messages with the second node, identifying whether an anti-flag is stored in the first node, the anti-flag being assigned when each message arrives at a destination node, flooding of a non-anti-flagged message among the messages stored in the first node to the second node, and flooding of an anti-flagged message among the messages stored in the first node to the second node according to at least one of situation information including a hop count, a Time-To-Live (TTL) and a number of requester nodes of the corresponding message and a mobility of the first node, or restricting the flooding to the second node.
