Since wireless network virtualization enables abstraction and sharing of infrastructure and radio spectrum resources, the overall expenses of wireless network deployment and operation can be reduced significantly. Moreover, wireless network virtualization can provide easier migration to newer products or technologies by isolating part of the network. Despite the potential vision of wireless network virtualization, several significant research challenges remain to be addressed before widespread deployment of wireless network virtualization, including isolation, control signaling, resource discovery and allocation, mobility management, network management and operation, and security as well as non-technical issues such as governance regulations, etc. In this paper, we provide a brief survey on some of the works that have already been done to achieve wireless network virtualization, and discuss some research issues and challenges. We identify several important aspects of wireless network virtualization: overview, motivations, framework, performance metrics, enabling technologies, and challenges. Finally, we explore some broader perspectives in realizing wireless network virtualization.
Wireless network virtualization is needed to build a virtual network over wireless and wired networks, which enables a rapid deployment of novel mobile services or novel mobile network architectures on a shared infrastructure. This paper proposes an airtime-based resource control technique for wireless network virtualization, in which wireless network resources are allocated among competing virtual networks while keeping their programmability. A WLAN system adopting the proposed technique is developed by enhancing an IEEE 802.11e EDCA (Enhanced Distributed Channel Access) MAC (Media Access Control) mechanism. The operation of the resource control technique is demonstrated by a simulation and the performance of airtime usage and throughput are investigated. It is shown that technique can successfully control the wireless network resource allocations with a target ratio even under conditions when the WLAN system suffers interferences.
The 5G wireless network which is regarded as the future critical infrastructure, is faced with many formidable challenges. To deal with them, resource sharing is the trend, including sharing the wireless resources and the infrastructure. Thus, the wireless network virtualization has been raised to integrate and abstract the resources and make network management more flexible. In this paper, a wireless network virtualization architecture is designed, which consists of the cognitive plane, the control plane and the data plane. These three planes collaborate to optimize the resource allocation according to the network condition. Then, we introduce the cell clustering method in the proposed architecture, which can largely reduce the complexity of resource slicing and make it possible in wireless network. Finally, we have implemented a trial environment to test the architecture. The test data indicate the network performance is obviously improved. Spectrum efficiency is doubled and the packet loss rate reduces to 1/20.
The current network is designed for peak loads, which results in lower network resource utilization and great energy waste. In case of meeting the wireless coverage and user requirements, how to make more base stations in wireless networks into a sleeping state has become an important means of energy saving. Virtualization network technology makes it possible that centralized scheduling wireless network resources and deploying intelligent energy perception network. According to the characteristics of the underlying virtual network mapping and base station energy consumption situation, the virtual cell resource mapping multi-objective decision making energy saving model is proposed in this paper. And then, the two-step mapping algorithm is used for solving the model. At last, the results of theoretical analysis and simulation experiments show that this algorithm can effectively reduce the system energy consumption.
We study the problem of joint user clustering and resource allocation for wireless network virtualization (WNV) using non-orthogonal multiple access (NOMA). We aim to maximize the weighted total sum-rate while taking into account the isolation constraint of the mobile virtual network operators (MVNOs). To solve the non-convex formulated problem, we decouple it into three subproblems, i.e., user clustering, resource block (RB) allocation and power assignment. We apply the framework of matching game with externalities to solve the user clustering problem while the solutions for RB and power allocation are derived by using the Lagrange dual approach and complementary Geometric programming, respectively. An alternative maximization algorithm is provided to achieve a suboptimal solution for the original problem. We propose to classify user equipments (UEs) into three classes, i.e., strong, normal and weak UEs and compare our proposed scheme with general NOMA scheme with two UEs per cluster. Simulation results revel a performance gain of 2.5% in terms of throughput. Moreover, the proposed scheme outperforms the traditional OFDMA scheme in terms of throughput and energy efficiency by up to 40% and 58%, respectively.
In existing urban rail transit systems, the train-ground communication system for different subsystems is deployed independently. Investing and constructing the communication infrastructures repeatedly not only wastes substantial social resources, but it also is difficult to maintain all these infrastructures. In this paper, we propose an integrated train-ground communication system based on wireless network virtualization for urban rail transit systems. In order to improve the communication-based train control (CBTC) subsystem performance during handoff, we propose a novel handoff scheme to support handoff between virtual networks. The application-layer quality-of- service (QoS) parameters of the CBTC, passenger information system, and closed circuit television subsystems are used as the performance measures in the handoff design. We then formulate the QoS optimization problem in the proposed integrated train-ground communication system as an approximate dynamic programming (ADP) problem. The extensive simulation results show that the proposed integrated train-ground communication system QoS can be improved substantially with our ADP-based optimization model.
We propose a new framework for wireless network virtualization. In this framework, service providers (SPs) and the network operator (NO) are decoupled from each other: The NO is solely responsible for spectrum management, and SPs are responsible for quality-of-service (QoS) management for their own users. SPs compete for the shared wireless resources to satisfy their distinct service objectives and constraints. We model the dynamic interactions among SPs and the NO as a stochastic game. SPs bid for the resources via dynamically announcing their value functions. The game is regulated by the NO through: 1) sum-utility optimization under rate region constraints; 2) enforcement of Vickrey-Clarke-Groves (VCG) mechanism for pricing the instantaneous rate consumption; and 3) declaration of conjectured prices for future resource consumption. We prove that there exists one Nash equilibrium in the conjectural prices that is efficient, i.e., the sum-utility is maximized. Thus, the NO has the incentive to compute the equilibrium point and feedback to SPs. Given the conjectural prices and the VCG mechanism, we also show that SPs must reveal their truthful value functions at each step to maximize their long-term utilities. As another major contribution, we develop an online learning algorithm that allows the SPs to update the value functions and the NO to update the conjectural prices iteratively. Thus, the proposed framework can deal with unknown dynamics in traffic characteristics and channel conditions. We present simulation results to show the convergence to the Nash equilibrium prices under various dynamic traffic and channel conditions.
Wireless network virtualization (WNV) has drawn attention from the researchers ranging from academia to industry as one of the significant technologies in the cellular network communication. It is considered as a pioneer to achieve effective resource utilization with decreased operating expenses and capital expenses by decoupling the networks functionalities of coexisting virtual networks. It facilitates fast deployment of new services and novel technologies. WNV paradigm is in the early stages, and there is a large room for the research community to develop new architectures, systems, and applications. The availability of software-defined networking (SDN) and cloud/centralized radio access network (C-RAN) steers up the hope for the WNV realization. This paper surveys WNV along with the recent developments in SDN and C-RAN technologies. Based on these technologies and WNV concepts, we identify the requirements and opportunities of future cellular networks. We then propose a general architectural framework for the WNV based on SDN. In- depth discussion of challenges and research issues as well as promising approaches for future networks communication improvements are also proposed. Finally, we give several promising candidates of future network services for residential customers and business customers.
Wireless network virtualization is identified as one of the key enabling technologies to bring fifth-generation networks into fruition. In this letter, we model the service selection and resource purchasing problem as a two-stage combinatorial optimization problem. To solve this problem, we propose a hierarchical matching game-based scheme, which satisfies the efficient resource allocation and strict isolation requirements. Simulation results show that our proposal outperforms the fixed sharing approach by 32% and achieves up to 97% of performance obtained by the optimal approach (general sharing scheme) in terms of average sum rate.
Infrastructure providers (InPs) can provide virtual networks (VNs) to service providers (SPs) through wireless network virtualization. These VNs share the wireless spectrum and they are supposed to meet various requirements of different SPs. In order to satisfy the requirements such as quality of service (QoS), fairness and isolation, efficient and flexible slicing and scheduling schemes are necessary. In this paper, to meet the different rate requirements of VNs, we propose a novel slicing and scheduling scheme. In this scheme, each VN is assigned a certain number of sub-channels to provide services to its users. This number is changeable, which reflects the dynamic adjustability of our scheme. Scheduling isolation among VNs is realized in this scheme, which means that users in different VNs will not be scheduled together, and different scheduling schemes can be used for different VNs based on our scheme. Simulation results show that our scheme provides a good balance between fairness and throughput. More importantly, it provides an efficient method for meeting different rate targets of VNs.
