Network slicing has recently appeared as one of the most important features that will be provided by 5G networks and is attracting considerable interest from industry and academia. At the wireless edge of these networks, most of the contributions in this area are related to cellular technologies leaving behind WiFi networks. In this work, we present a resource allocation mechanism based on airtime assignment to achieve infrastructure sharing and slicing in WiFi Access Points. The approach is simple and has the potential to be straightforwardly used within scenarios of wireless access infrastructure sharing.

IoT environment has spread and the use of Internet services during move has increased recently. The demand for mobility management, the technology to keep communication even when a communicating mobile node moves, is growing due to it. We proposed a SDN based mobility management scheme in our prior work to deal with inter-domain handovers, but its routing algorithm only considers the number of domains to go through and the number of flow entries to install. This prevents us from selecting suitable routes. In this paper, we show the design of a new routing mechanism that considers various parameters. This mechanism suppresses costs for changing route to carry out handover smoothly and avoids lengthy routes.

The Network Access Control (NAC) management is a critical task, especially in current networks that are composed of many heterogeneous things (Internet of Things) connected to share data, resources and Internet access. The Software-Defined Networking (SDN) simplifies the network design and operation, and offers new opportunities (programmability, flexibility, dy-namicity, and standardization) to manage the network. Despite this, the access control management remains a challenge, once managing security policies involves dealing with a large set of access control rules, detecting conflicting policies, defining priorities, delegating rights, and reacting against network state changes and events. This work presents the HACFlow, a novel, autonomic, and policy-based framework for access control management in OpenFlow networks. HACFlow aims to simplify and automate the network management allowing network operators to govern rights of network entities by defining dynamic, fine-grained, and high-level access control policies. We analyzed the performance of HACFlow and compared it against related approaches.
网络访问控制(NAC)管理是一项至关重要的任务，特别是在当前由许多异构物(Internet of things)组成的网络中，共享数据、资源和互联网访问。软件定义网络(SDN)简化了网络的设计和运行，为网络管理提供了新的机会(可编程性、灵活性、动态性和标准化)。尽管如此，访问控制管理仍然是一个挑战，一旦管理安全策略涉及处理大量访问控制规则集，检测冲突策略，定义优先级，授权以及对网络状态变化和事件做出反应。这项工作提出了HACFlow，一个新颖的、自主的、基于策略的框架，用于OpenFlow网络中的访问控制管理。HACFlow旨在简化和自动化网络管理，允许网络运营商通过定义动态的、细粒度的、高级的访问控制策略来管理网络实体的权限。我们分析了HACFlow的性能，并将其与相关方法进行了比较。

Many enterprises rely on cloud infrastructure to host their critical applications (such as trading, banking transaction, airline reservation system, and credit card authorization). The unavailability of these applications may lead to severe consequences that go beyond the financial losses, reaching the cloud provider reputation too. However, to maintain high availability in a cloud data center is a difficult task due to its complexity. The power subsystem is crucial for the entire operation of the data center because it supplies power for all other subsystems, including IT components and cooling equipment. Some studies have already proposed models to evaluate the availability of the power subsystem, but none of them are based on standard redundancy models. Standards guide cloud providers regarding availability, points of failure, and watts per square foot based on components' redundancy. This paper proposes RBD and Petri Net models based on the TIA-942 standard to estimate the availability of the data center power subsystem and analyze how failures on power subsystem impact the availability of critical applications. These models are important to resource planning and decision making by the cloud providers, because they may identify which components they ought to invest in order to improve the availability level.

In order that the Internet of Things (IoT) realize its full potential, it has been claimed for the IoT industry to follow the smartphone recipe of market-creating innovation. Indeed, the main mobile apps platforms derive a significant part of their brand value and pricing power from their reputation to have most innovative apps coming to them. Having witnessed that the same steady stream of developer-driven innovation is already emerging in IoT, demand for IoT-based services will be driven by this growing innovative community of IoT developers. In order to make it possible, main players should focus on building platforms that support third party applications instead of developing applications for their own devices. As a way to materialize the above idea, we propose a business model for IoT-based services where a platform creates a multisided market. The business model comprises a platform that serves as an intermediary between human users, app developers and Wireless Sensor Networks, so that the users use the apps, and the apps process the data supplied by the sensor networks. The platform, acting as a monopolist, posts a fee for each of the three sides so as to maximize its profit. We conduct an analysis of the profit maximization problem faced by the platform. We show that the relative strength of the value that advertisers attach to the users determines the platform price structure. All in all, a high valuation is beneficial for all agents (users, platform, developers, and WSNs).

The number of connected mobile devices is increasing rapidly with more than 10 billion expected by 2022. Their total aggregate energy consumption poses a significant concern to society. The current 3gpp (3rd Generation Partnership Project) LTE/LTE-Advanced standard incorporates an energy saving technique called discontinuous reception (DRX). It is expected that 5G will use an evolved variant of this scheme. In general, the single selection of DRX parameters per device is non trivial. This paper describes how to improve energy efficiency of mobile devices by selecting DRX based on the traffic profile per device. Our particular approach uses a two phase data-driven strategy which tunes the selection of DRX parameters based on a smart fast energy model. The first phase involves the off-line selection of viable DRX combinations for a particular traffic mix. The second phase involves an on-line selection of DRX from this viable list. The method attempts to guarantee that latency is not worse than a chosen threshold. Alternatively, longer battery life for a device can be traded against increased latency. We built a lab prototype of the system to verify that the technique works and scales on a real LTE system. We also designed a sophisticated traffic generator based on actual user data traces. Complementary method verification has been made by exhaustive off-line simulations on recorded LTE network data. Our approach shows significant device energy savings, which has the aggregated potential over billions of devices to make a real contribution to green, energy efficient networks.

Standardisation, research and development efforts for the fifth generation (5G) of mobile telecommunication networks are well under way. Software Defined Networking (SDN) and Network Function Virtualisation (NFV) are two of the key enabling technologies, considered in these efforts. The need for a flexible, high performant and efficient architecture is well established. Network slicing, which combines SDN and NFV, can contribute to such an architecture. It allows the parallel deployment of differing network stacks on top of any physical infrastructure. SDN's separation of control and data plane components allows for flexible deployments. How can SDN's flexibility be leveraged in a sliced, 5G network infrastructure? There needs to be an efficient way to integrate SDN into 5G networks. In this paper, we posit a way of integration, which allows decoupling the data plane components from any particular control plane. This can improve flexibility, utilisation and extensibility. We envision utilising an SDN switch implementation as the User Plane Function (UPF), and introducing an SDN controller between Session Management Function (SMF) and UPF, to effectively decouple the two. Based on this decoupling, control and data plane components can be deployed in separatelyand new slice orchestration opportunities can be developed. Furthermore, we can leverage deep data plane programmability, to enhance the system in terms of function and flexibility.

New wireless technologies with enhanced multiband capabilities will have a strong impact on spectrum management. While radio access technologies become more flexible in terms of usable spectrum, authorization regimes need to be rethought. Regulators thus will be expected to set the stage for more flexible spectrum usage scenarios in combination with a heterogeneous set of applications and services. In contrast to the current command and control approach, spectrum management would encompass the definition of abstract access and usage rules applicable to a variety of applications. Consequently, impact assessment of regulatory measures in regimes with increased flexibility and heterogeneity requires detailed ex-ante modelling with a strong focus on dynamic components. In this paper, it is argued that neither technical bottom-up nor economical top-down modeling on its own serves the goal to capture the dynamics of a flexible environment to a sufficient degree. To fill the gap, a combined simulation framework is proposed to model authorization procedures in a nationwide spectrum management ecosystem based on multiple local scenarios.

Mobile computation offloading has recently attracted much interest and first offloading solutions have been developed. However, the relevant technical challenge of how to automatically determine offloadable sections of Android applications has not been adequately investigated so far. This paper proposes an innovative task selection algorithm that can parse an Android application autonomously and classify all the methods based on their offloadability by adopting a finegrained and multi-steps analyzer. The reported experimental results show the effectiveness of our solution when applied to the top 25 most downloaded Android apps on the Google Play store, by showing its accuracy in identifying offloadable methods and demonstrating the potential benefits of automated mobile computation offloading.

5G networks are expected to support various applications with diverse requirements in terms of latency, data rates and traffic volume. Cloud-RAN and densely deployed small cells are two of the tools at disposal of Mobile Network Operators to cope with such challenges. In order to mitigate the fronthaul requirements imposed by the Cloud-RAN architecture, several functional splits, each characterized by a different demarcation point between the centralized and the distributed units, have emerged. However, the selection of the appropriate centralization level (i.e., the functional split) still remains a challenging task, since a number of parameters have to be considered in order to make such a decision. In this paper, a virtual network embedding (VNE) algorithm is proposed to flexibly select the appropriate functional split. The VNE is formulated as an Integer Linear Programming problem whose objective is to minimize the intercell interference and the fronthaul bandwidth utilization by dynamically selecting the appropriate functional split. Finally, a scalable VNE heuristic is also proposed.

Finally, a scalable VNE heuristic is also proposed.","PeriodicalId":211611,"journal":{"name":"2017 13th International Conference on Network and Service Management (CNSM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125524162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
