Abstract:
Provided is a method of data caching in delay tolerant network based on information centric network and a recording medium and a device for performing the same. The data caching method includes: the step of checking a remaining buffer amount and a buffer usage amount of node, the step of caching data in the node which is received from another node according to a data caching policy, in case remaining buffer amount of the node is greater than a preset remaining buffer amount threshold, the step of deleting data cached in the node from the node according to a data deletion policy, in case the buffer usage amount of the node is less than a preset buffer usage amount threshold, and the step of setting an initial Time-to-Live (TTL) value of the data received from another node or updating a TTL of the data cached in the node using information of the data received from another node or information of the node.
