vSPACE: VNF Simultaneous Placement, Admission Control and Embedding

In future wireless networks, network functions virtualization lays the foundations for establishing a new dynamic resource management framework to efficiently utilize network resources.‎ In this paper, a network service can be viewed as a chain of virtual network functions (VNFs), called a service function chain (SFC), served via placement, admission control (AC), and embedding into network infrastructure, based on the resource management objectives and the state of network.‎

Antenna Allocation and Pricing inVirtualized Massive MIMO Networks via Stackelberg Game,

We study a resource allocation problem for the uplink of a virtualized massive multiple-input multiple-output system, where the antennas at the base station are priced and virtualized among the service providers (SPs).‎ The mobile network operator (MNO) who owns the infrastructure decides the price per antenna, and a Stackelberg game is formulated for the net profit maximization of the MNO, while the minimum rate requirements of SPs are satisfied.‎

Leveraging synergy of SDWN and multi-layer resource management for 5G networks,

Fifth-generation (5G) networks are envisioned to predispose flexible edge-to-core infrastructure to offer diverse applications.‎ Convergence of software-defined networking, software-defined radio, and virtualisation on the concept of software-defined wireless networking (SDWN) is a promising approach to support such dynamic networks.‎ The principal technique behind the 5G-SDWN framework is the separation of control and data planes that allows the abstraction of resources as transmission parameters of users.‎

Multi-Objective Resource Allocation in Density-Aware Design of C-RAN in 5G

In this paper, a multi-objective resource allocation algorithm in a novel density-aware design of virtualized software-defined cloud radio access network (C-RAN) is proposed.‎ We consider two design modes based on the average density of users: 1) high-density mode when a large number of low-cost remote radio heads (RRHs) without baseband processing capability are controlled by one single base station and 2) low-density mode when a small number of RRHs with baseband processing capability are deployed.‎

Design optimization of NZDSF for low latency in iot optical fiber network

Due to ever–increasing demands for optical fibers with low–latency used in IoT optical fiber networks, in this theoretical study, a non–zero dispersion shifted fiber (NZDSF) with a particular refractive index which had a minimum latency at 1352 nm is designed.‎ In comparison to a commercial NZDSF, the latency has improved by 0.‎002ìs in the designed NZDSF with an effective area of 102 and macro bending loss of 517.‎3 /110−×dBkm.‎ The dispersion of this fiber is found to be 1.‎10625ps/nm.km which is comparable to the commercial NZDSF fiber.‎
