Abstract

Wireless Network Virtualization (WNV) and its integration with on-demand Internet provisioning shift the paradigm of network resource allocation, management, and consumption. WNV permits the disassociation of a physical radio infrastructure with entities that operate virtually in a network. This disassociation enables the spectrum, base stations, and the core network to be shared as infrastructure among service providers in a flexible and scalable manner. Integration with on-demand Internet provisioning, in theory, instantaneously provides applications and users with customized access to connectivity services with different QoS level guarantees that are decoupled from the physical infrastructure. The integration is aimed at solving the problems of the traditional wireless systems. This includes spectral resource underutilization rather than structural provisioning in the spectral network. Deploying the systems is expensive. The framework proposed in this paper, furthermore, adds a novel orchestration algorithm of virtualization-based resource allocation that slices virtual networks and optimally associates them to real-time user and service demand. Simulated performance evaluation results from real-world datasets show that the framework will increase resource utilization of the network by almost 40%, reduce network latency by 30%, and SLA compliance will be above 95% The following diagrams describe the system components, flows,and architecture, layers of virtualization and slice management, and the orchestration algorithm will be added. The optimization results in relation to proven scalability and security, alongside deployment difficulties. This paper closes with suggestions for future investigation in increasingly critical areas, such as orchestration driven by AI and integration with 5G and 6G architecture.
