Abstract:

Many virtual networks are built by utilizing network virtualization technologies on a substrate network withnetwork resources. Virtual service resources may be used to provide a particular service to users across each virtual network. Additionally, future network services are predicted to include network virtualization for mobile users. In mobile virtual networks, users often switch between nodes and connect to different access points. As a consequence, the virtual network's link and node traffic fluctuates. Because service quality is determined by the quantity of traffic on links and nodes, service quality varies with the user's movement.This study offers a method for replacing virtual service resources in virtual networks for mobile applications with dynamic resource allocation response to changing traffic. The number of resources for every node and every link in our suggested system is modified based on traffic changes. Furthermore, the virtual service resource is moved from a node to an adjacent node, and this substitution is continued until the service’s quality meets the specified quality. It is envisaged that the service qualityof the mobile customers would be maintained using our proposed strategy, even if the volume of traffic fluctuates. We measure the efficiency of our suggested technique utilizing simulation. It is shown via numerical examples that our suggested technique works well when there are more users involved and traffic fluctuates.
