A neighbor node packet mapping method in wireless network virtualization

The invention belongs to the technical field of communication, and relates to an adjacent node grouping mapping method in wireless network virtualization, which comprises the following steps of: arranging virtual network requests in a descending order according to mapping revenue of the virtual network requests; calculating the field values of the nodes in the maximum virtual network and arrangingthe field values in a descending order; traversing the physical network, finding out a set of physical nodes which can be mapped, and embedding the nodes into the physical nodes; screening out a nodedirectly connected with the central node and a node with a two-degree node of 1 of the central node as an edge node set, and calculating link aggregation pressure values of all physical nodes in a mappable physical node set of the edge nodes; selecting the physical node with the minimum link aggregation pressure value as a bearing node of the virtual network node for mapping; performing link mapping by using a K shortest
