METHOD AND APPARATUS FOR EMBEDDING RESOURCE FOR REQUEST FOR VIRTUAL NETWORK IN MOBILE ENVIRONMENT

摘要

PURPOSE: A resource embedding apparatus for the request of a virtual network in wireless environment and a method thereof are provided to efficiently allocate wireless network resources by considering the interference relations between wireless links when a virtual network request is received in the wireless network environment. CONSTITUTION: A first embedding unit(140) selects a first physical node by excluding a physical node which includes less resources than the resource requirement of a first virtual node. The first embedding unit embeds the first virtual node to the first physical node. A second embedding unit(150) maps a second virtual node to the second physical node. In the second physical node, the sum of weighted lengths from the embedded physical node among not embedded physical nodes is minimum.
