Abstract: A method of caching a content in a node in a content-centric network, includes receiving, from a content requester, a content request packet requesting a first chunk of the content, and setting a mark bit indicating whether the node is to cache the first chunk when the first chunk is received. The method further includes receiving, from a content provider, a data packet including the first chunk in response to transmitting the content request packet to the content provider, and caching the first chunk.

Abstract: In a method for communicating among a plurality of nodes in a content-centric networking environment, each of a plurality of nodes selects at least one relay node based on topology information on neighbor nodes adjacent within 2 hops from itself. Each of the selected relay nodes determines whether itself is a publisher relay node. Each of the determined publisher relay nodes generates a multi-hop content announce (CA) message including content information of its own 1-hop neighbor nodes, and broadcasts the multi-hop CA message to the plurality of nodes through the selected relay nodes.

Abstract: Disclosed herein non-infrastructure ultra-wideband wireless positioning method and system using latency communication and overhear. The method includes: receiving a ranging message transmitted from other active devices; measuring a location of an active device by using data obtained from the ranging message; checking a remaining amount of power of the active device and creating a ranging message by using the remaining amount of power of the active device and the obtained data; and transmitting the created ranging message to the other active devices. When a request of device change is received from a first passive device based on a remaining amount of power of a passive device overhearing the ranging message and the remaining amount of power of the active device, a response for changing the first passive device to an active device is provided, and the active device itself changes from an active device to a passive device.
