Abstract: A system for providing an adaptive AR streaming service may comprise: a cloud AR server that stores an AR object composed of a plurality of progressive mesh chunks, and a meta file including property information of the AR object and the progressive mesh chunks; and a mobile augmented reality (AR) device that requests and receives the meta file from the cloud AR server, parses the meta file to identify a property of the AR object, and implements augmented reality.

Abstract: Provided is a system and method for estimating an end-to-end delay between blockchain nodes in peer-to-peer (P2P) networks. The system includes a coordinate system construction unit configured to designate an origin node and anchor nodes among participating nodes having a distributed ledger of P2P networks, construct a first coordinate system of a predetermined dimension by exchanging control messages between the origin node and the anchor nodes and the participating nodes, and construct a second coordinate system of another predetermined dimension and a dimension determination unit configured to determine a dimension to be applied to the current P2P networks by comparing dimension-specific delays or control message overheads of the first coordinate system and the second coordinate system.
