In the future, the Internet of Things will become increasingly important in a Smart City, for example. Today, however, established radio standards in license-free bands show that radios in heterogeneous networks interfere with each other. This includes radio standards in particular in the license-free 2.4 GHz ISM band. In this publication, we investigate IEEE 802.15.4 and IEEE 802.11 and show how radios in heterogeneous networks coordinate their actions in order to share radio resources. With the Extended Network Allocation mechanism, we demonstrate that IEEE 802.15.4 frame losses are reduced by a maximum of 50 percent even if strong interference occurs. We also show the design and implementation of an Extended Network Allocation enabled Gateway for the Internet of Things and provide a detailed description. For evaluation, we conduct measurements in a real-world application and environment.
未来,物联网将变得越来越重要,例如在智慧城市中。然而,今天在免许可证频带中建立的无线电标准表明,异构网络中的无线电相互干扰。这包括无线电标准,特别是在免许可的2.4 GHz ISM频段。在本出版物中,我们研究了IEEE 802.15.4和IEEE 802.11,并展示了异构网络中的无线电如何协调其行动以共享无线电资源。使用扩展网络分配机制,我们证明即使发生强干扰,IEEE 802.15.4帧丢失也最多减少50%。我们还展示了用于物联网的扩展网络分配网关的设计和实现,并提供了详细的描述。为了进行评估,我们在真实的应用程序和环境中进行测量。

Public healthcare is a major priority in today’s society. With the introduction of wearable devices, monitoring, detecting and preventing health conditions has become cheaper and easier. On the down side, transmitting and storing all this sensitive data poses new challenges. We propose an original solution for securing the transmission of data gathered by sensors in a Wireless Body Area Network using the Electrocardiogram signal and Named Data Networks. Our contribution is two-fold: first of all, we make use of the inherent features of such networks to securely transmit sensitive, health-related data (of a regular patient or a driver) to the cloud and then disseminate it to interested parties such as physicians. Second, our approach exploits the properties of the Electrocardiogram signal (robustness to attacks, universality and liveness detection) to encrypt this data and provide a simple and fast authentication mechanism between the devices in the Wireless Body Area Network.

This paper addresses edge computing for location-based service where location data is obtained by Internet of Things devices. A key motivation of the paper is to propose a location-based routing/forwarding framework where a computation request of location data is forwarded to an appropriated edge router. The word “appropriate” means that time of retrieving location data as an argument of the computation is minimized. As the result, computing time is minimized.

A major goal of the H2020 Inter-IoT project is to provide a framework for seamless integration of different Internet of Things (IoT) platforms. To allow the Inter-IoT user to interact with those platforms, which feature their own syntax and Application Programming Interfaces (APIs), so called bridges are designed and implemented. For ensuring interoperability, semantics play a key role. The ontologies used by the different platforms need to be aligned with a central ontology. We present the features supported by Inter-IoT’s Inter-MiddleWare layer and discuss the operation of a bridge towards a oneM2M based platform.
H2020 Inter-IoT项目的一个主要目标是为不同物联网(IoT)平台的无缝集成提供一个框架。为了允许Inter-IoT用户与那些具有自己的语法和应用程序编程接口(api)的平台进行交互,所谓的桥被设计和实现。为了确保互操作性,语义起着关键作用。不同平台使用的本体需要与一个中心本体保持一致。我们介绍了Inter-IoT的Inter-MiddleWare层所支持的特性,并讨论了基于oneM2M平台的桥接操作。

Multiple-access Edge Computing (MEC) has been proposed as a means to minimize the user to service path latency, by deploying and operating datacenter resources close to the network edge. The introduction of 5G mobile network services, and their provisioning through disaggregated base stations complying with the Cloud-RAN paradigm, allows the redefinition of the traditional Edge Computing by offering deployment of services even closer to the network access edge. In this work, we leverage a disaggregated heterogeneous 5G infrastructure, compliant with the 5G New Radio (NR) specifications, and present a scheme for placing the services even closer to the Edge, close to the concept of fog computing. We develop a scheme for the OpenAirInterface platform that allows services to be executed close or over the machines hosting the radio services for the network access. By exploiting features for integrating heterogeneous radio resources in the cell, we are able to create a controller interface for selecting the optimal radio access technology used to serve each user of the network from the MEC service perspective. We evaluate our solution in a real testbed setup, and measure performance related indicators for our solution by using adaptive video streaming. Our results illustrate up to 80% better video qualities delivered to the end user when appropriately selecting the access technology.
多址边缘计算(MEC)是一种通过部署和操作靠近网络边缘的数据中心资源来最小化用户到服务路径延迟的方法。5G移动网络服务的引入,以及通过符合Cloud-RAN范式的分解基站提供服务,通过提供更接近网络接入边缘的服务部署,可以重新定义传统的边缘计算。在这项工作中,我们利用了一个分解的异构5G基础设施,符合5G新无线电(NR)规范,并提出了一个方案,使服务更接近边缘,接近雾计算的概念。我们为OpenAirInterface平台开发了一种方案,该方案允许服务在承载网络访问的无线电服务的机器附近或之上执行。通过利用在小区中集成异构无线电资源的特性,我们能够创建一个控制器接口,用于选择用于从MEC服务角度为网络的每个用户服务的最佳无线电接入技术。我们在一个真实的测试平台设置中评估我们的解决方案,并通过使用自适应视频流测量我们的解决方案的性能相关指标。我们的结果表明,当适当选择接入技术时,向最终用户提供的视频质量可提高80%。

In Adaptive Bit Rate (ABR) utilized in MPEG-DASH (MPEG Dynamic Adaptive Streaming over HTTP), there have been proposed three representative algorithms, rate-based, buffer-based and hybrid-based ones. In the information centric networks, which have been widely studied as a network architecture for efficient content distribution including video streaming, routers are generally equipped with cache storage. When some segments of a required content is occasionally downloaded from cache storage in a router, content download from a router might be faster than segment retrieval from the original content server. This inaccurate throughput estimation might lead to inappropriate bitrate selection of ABR algorithm running on the user’s application and significant degradation of QoE (Quality of Experience) performance. In this paper, from the viewpoint of QoE, we evaluate the influence of in-network caches on three types of ABR algorithm in video streaming.
在MPEG- dash (MPEG Dynamic Adaptive Streaming over HTTP)中使用的自适应比特率(ABR)算法中,提出了基于速率的、基于缓冲区的和基于混合的三种代表性算法。信息中心网络作为一种高效内容分发(包括视频流)的网络架构已被广泛研究,路由器通常配备缓存存储。当偶尔从路由器的缓存存储中下载所需内容的某些片段时,从路由器下载内容可能比从原始内容服务器检索片段要快。这种不准确的吞吐量估计可能会导致在用户应用程序上运行的ABR算法的比特率选择不适当,并且会显著降低QoE(体验质量)性能。本文从QoE的角度,评估了网络内缓存对视频流中三种ABR算法的影响。

Are Darknets All The Same? On Darknet Visibility for Security Monitoring 暗网都一样吗?用于安全监控的暗网可见性研究

Darknets are sets of IP addresses that are advertised but do not host any client or server. By passively recording the incoming packets, they assist network monitoring activities. Since packets they receive are unsolicited by definition, darknets help to spot misconfigurations as well as important security events, such as the appearance and spread of botnets, DDoS attacks using spoofed IP address, etc. A number of organizations worldwide deploys darknets, ranging from a few dozens of IP addresses to large /8 networks. We here investigate how similar is the visibility of different darknets. By relying on traffic from three darknets deployed in different contintents, we evaluate their exposure in terms of observed events given their allocated IP addresses. The latter is particularly relevant considering the shortage of IPv4 addresses on the Internet. Our results suggest that some well-known facts about darknet visibility seem invariant across deployments, such as the most commonly contacted ports. However, size and location matter. We find significant differences in the observed traffic from darknets deployed in different IP ranges as well as according to the size of the IP range allocated for the monitoring.
暗网是一组IP地址,它们被发布,但不承载任何客户端或服务器。通过被动地记录传入的数据包,它们有助于网络监控活动。由于它们收到的数据包根据定义是未经请求的,因此暗网有助于发现错误配置以及重要的安全事件,例如僵尸网络的出现和传播,使用欺骗IP地址的DDoS攻击等。世界范围内的许多组织都部署了暗网,范围从几十个IP地址到大型/8网络。我们在这里调查不同暗星系的可见性有多相似。通过依赖部署在不同大陆的三个暗网的流量,我们根据观察到的事件评估了它们的暴露程度,并给出了它们分配的IP地址。考虑到互联网上IPv4地址的短缺,后者尤其重要。我们的研究结果表明,关于暗网可见性的一些众所周知的事实似乎在部署中是不变的,例如最常接触的端口。然而,规模和位置很重要。我们发现部署在不同IP范围内的暗网以及分配用于监控的IP范围的大小所观察到的流量有显著差异。

Video streaming is the most popular application on today’s Internet. Millions of people around the globe access video contents using various end user devices, such as smart phones, tablets, laptops, and TVs. To meet the requirements of different end user devices and variable network conditions, videos need to be encoded into different quality versions before delivery to the clients. Such large-scale encoding tasks consume significant amounts of energy. In this paper, we investigate to what extent the realtime video encoding clouds can be powered by renewable energy sources. We show that video encoding tasks are suitable for execution on clouds that are powered by a combination of renewable and grid energy sources. With the use of our power management policies, grid energy usage can be reduced by 73–83%, which leads to electricity cost reductions of 14–28% compared to unlimited non-renewable power.
视频流是当今互联网上最流行的应用。全球数百万人使用各种终端用户设备(如智能手机、平板电脑、笔记本电脑和电视)访问视频内容。为了满足不同终端用户设备和不同网络条件的需求,视频在交付给客户端之前需要编码成不同质量的版本。这种大规模的编码任务消耗了大量的能量。在本文中,我们研究了实时视频编码云在多大程度上可以由可再生能源供电。我们展示了视频编码任务适合在由可再生能源和网格能源组合提供动力的云上执行。通过使用我们的电力管理政策,电网能源使用量可以减少73-83%,与无限的不可再生能源相比,电力成本降低了14-28%。

Critical Reroute: A Practical Approach to Network Flow Prioritization using Segment Routing 关键重路由:使用分段路由实现网络流优先级的实用方法
Pub Date : 2019-07-01 DOI: 10.1109/LANMAN.2019.8846997

It is widely recognized that reliable communications are a key element of a successful response to a disaster situation. To address this need, local and regional governments in all parts of the world have deployed dedicated communications networks for first responders. These systems are often prohibitively expensive, voice-only, and are needed only on rare occasions. It would be more cost-effective to use already-existing networks or to deploy networks for shared use. However, due to the sudden increase in demand or physical failure caused by the disaster, shared networks may become overloaded. In such situations, it would be desirable to prioritize traffic flows belonging to public safety applications over others. Solutions such as priority queuing and differentiated services provide partial answers to that goal but leave other problems unsolved. This work presents a novel solution using Segment Routing and a Genetic Algorithm optimizer to minimize the impact of network overload on critical traffic flows. The results show that these methods can reroute flows using a single midpoint such that the total network overload is reduced compared to traditional shortest-path routing while avoiding unnecessarily long paths and taking priority of flows into account.
人们普遍认识到,可靠的通信是对灾害情况作出成功反应的关键因素。为了满足这一需求,世界各地的地方和区域政府都为第一响应者部署了专用通信网络。这些系统通常非常昂贵,只支持语音,并且只在很少的情况下才需要。使用已经存在的网络或部署网络供共享使用将更具成本效益。但是,由于需求的突然增加或灾难造成的物理故障,共享网络可能会过载。在这种情况下,最好优先考虑属于公共安全应用的交通流量。诸如优先级排队和差异化服务之类的解决方案为该目标提供了部分答案,但没有解决其他问题。这项工作提出了一种新的解决方案,使用分段路由和遗传算法优化器来最大限度地减少网络过载对关键流量的影响。结果表明,这些方法可以使用单个中点重新路由流,这样与传统的最短路径路由相比,总网络过载减少,同时避免了不必要的长路径并考虑了流的优先级。

To address this need, local and regional governments in all parts of the world have deployed dedicated communications networks for first responders. These systems are often prohibitively expensive, voice-only, and are needed only on rare occasions. It would be more cost-effective to use already-existing networks or to deploy networks for shared use. However, due to the sudden increase in demand or physical failure caused by the disaster, shared networks may become overloaded. In such situations, it would be desirable to prioritize traffic flows belonging to public safety applications over others. Solutions such as priority queuing and differentiated services provide partial answers to that goal but leave other problems unsolved.
