The Software Defined Wireless Networks is actively using NFV (network virtualization technology), which allows you to virtualize the machine network components using software.  Launched on NFV nodes (special virtual machines Support NFV Technology) Network Software Components are called Virtualized  Network Functions(VNF).  To provide services to the user, a multiple VNF can be combined into one SFC chain.  But when using the service, the user can move, which negatively affects the service.  However, VNF can be moved to the nearest NFV node.  In this article, we will consider several methods of dynamic VNF placement.
