Abstract: The present disclosure provides a method for processing data by an edge node including: receiving a data request from an application; confirming whether first data corresponding to the data request is included in a content storage of the edge node;
confirming whether there is second data having a correlation with the first data which is equal to or higher than a predetermined threshold value based on a previously stored mapping table when the first data is not included in the content storage of the edge node; and transmitting the second data to the application when there is the second data having the correlation with the first data which is equal to or higher than the threshold value.-

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.

Abstract: A visco-poroelastic elastomer-based capacitor type tactile sensor includes a first electrode, an active layer formed on a top surface of the first electrode and made of a visco-poroelastic elastomer, a second electrode formed on a top surface of the active layer, and a controller configured to provide an electric field generated orthogonal to an extension direction of the first electrode and the second electrode between the first electrode and the second electrode. In proportion to an external pressure applied to the tactile sensor, a concentration of effective ions present at the interfaces between the active layer and the first and second electrodes is increased.
