While the use of anomaly detection in network security has a long research history, it is rarely used in practice. Besides privacy concerns when applied in cross-network settings, and a more difficult attack interpretation, the major drawback consists of the high number of false alarms. One reason is the heterogeneity of sources the model is trained on. In this paper, we propose a network anomaly detection extension that counteracts the heterogeneity of participants by dividing them into learning groups during central or federated training. The learning groups finally contain similar behaving clients, e.g., light bulbs, or PCs of the same department. Similar behavior is extracted by hierarchically clustering the predictions of all individual client models similar to a passive property inference attack. Our preliminary results based on infiltration attacks of the IDS2017 dataset show that the method increases the accuracy and F1 score up to 4.4% and 2.5%, respectively.

Future Internet of Things (IoT) applications, such as connected industry 4.0, become more challenging with the strict Quality of Service (QoS) requirements, including reliability and delay guarantees. Several mechanisms in the communication stack to match the expected QoS are already discussed and specified at different layers, with the goal to make the communication more reliable. They focus on the layer-specific enhancements. For example, Time-Slotted Channel Hopping (TSCH) is a link layer mechanism to avoid narrowband interference. On the network layer, several multi-path routing schemes are proposed to distribute the traffic load or to have backup paths with the purpose of making data transmissions more robust to link failures. In addition to the layer-specific improvements, an integration of the cross-layer information can guarantee an end-to-end QoS for communication in dynamic environments. In this work we propose and evaluate a cross-layer framework for cell- disjoint routing, which eliminates overlapping resource scheduling in both time and frequency. It enables the end-to-end QoS for wireless sensor networks under the IPv6 Over the TSCH Mode of IEEE 802.15.4 (6TiSCH). The proposed framework, called 6TiSCH stack with cross-layer information exchange (6TiSCH-CLX), is validated on a selected set of aviation industry applications using both simulations and analytical model.
未来的物联网(IoT)应用，如互联工业4.0，由于严格的服务质量(QoS)要求，包括可靠性和延迟保证，将变得更具挑战性。为了使通信更加可靠，已经在不同的层讨论和指定了通信堆栈中的几种机制来匹配预期的QoS。它们侧重于特定于层的增强。例如，时隙信道跳频(TSCH)是一种避免窄带干扰的链路层机制。在网络层，提出了几种多路径路由方案，以分配流量负载或具有备份路径，从而使数据传输在链路故障时更加健壮。除了特定于层的改进之外，跨层信息的集成可以保证动态环境中通信的端到端QoS。在这项工作中，我们提出并评估了一个跨层的蜂窝不连接路由框架，该框架消除了在时间和频率上重叠的资源调度。它实现了IEEE 802.15.4 (6TiSCH)的IPv6 Over TSCH模式下无线传感器网络的端到端QoS。所提出的框架被称为具有跨层信息交换的6TiSCH堆栈(6TiSCH- clx)，在一组选定的航空工业应用中使用仿真和分析模型进行了验证。

Whereas adaptive video streaming for 2D video is well established and frequently used in streaming services, adaptation for emerging higher-dimensional content, such as point clouds, is still a research issue. Moreover, how to optimize resource usage in streaming services that support multiple content types of different dimensions and levels of interactivity has so far not been sufficiently studied. Learning-based approaches aim to optimize the streaming experience according to user needs. They predict quality metrics and try to find system parameters maximizing them given the current network conditions. With this paper, we show how to approach content and network adaption driven by Quality of Experience (QoE) for multi-dimensional content. We describe components required to create a system adapting multiple streams of different content types simultaneously, identify research gaps and propose potential next steps.

Upcoming communication systems increasingly often tackle the spectrum scarcity problem through the coexistence with legacy systems in the same frequency band. Cognitive Radio presents popular methods for Dynamic Spectrum Access (DSA) that enable coexistence. Historically, DSA meant a separation solely in the frequency domain, while in recent years it has been extended through the dimension of time, by employing Machine Learning to learn semi-deterministic and cyclic medium access patterns of the legacy system that are observed through channel sensing. When this pattern is learnable, then a new system can utilize a neural network and predict future medium accesses, thus steering its own medium access. We investigate this novel and more fine-grained version of DSA, propose a predictor and show its capability of reliably predicting future medium accesses of a legacy system in an aeronautical coexistence scenario. We extend the predictor to the case of partial observability, where only a narrowband receiver is available, s.t. observations are limited to a single sensed channel per time slot. In particular, we propose a custom loss function that is tailored to partially observable environments. In the spirit of Open Science, all implementation files are released under an open license.

When analyzing the impact of a communication system on the Quality of Experience (QoE) of an interactive application, simulation and mathematical modeling typically require reimplementation or modeling of the application under test and only provide insights in terms of selected Key Performance Indicators (KPIs), which raises the need for network emulation. In this demo, we present FlowEmu, an open-source flow-based network emulator that allows the user to manipulate the underlying model and analyze various statistics in real-time via an easy-to-use Graphical User Interface (GUI), by using interactive game streaming as an example application.

Applications involving multiple UAVs have gained increasing relevance in recent years, due to the benefits that cooperative systems tend to provide to their applications. In addition to performing several simultaneous tasks, the time spent to perform a certain task is reduced. In this article, an architecture for sharing navigation information is demonstrated to support applications composed of systems with multiple UAVs.

Internet eXchange Points (IXPs) around the world bring thousands of ISPs together to form dense peering fabrics. Since bilateral BGP peering sessions alone would result in large overhead, many IXPs offer route servers enabling the exchange of routing information with the entire peering population over a single multilateral BGP session. Route servers also perform RPKI validation to combat the lack of authentication and security in BGP. SCION is a novel inter-domain routing architecture addressing the security flaws of BGP by replacing it with a security and reliability centric clean-slate approach. We envision that operators of SCION ASes will be just as open to peering at Internet exchanges as they are today with BGP. Moreover, to fully utilize SCION's multipath capabilities SCION AS operators tend to deploy more different AS numbers than in BGP, further increasing the potential number of unique peering links at an IX. Since SCION has no native multilateral peering support, we propose the SCION peering coordinator, an IXP-hosted service automating SCION peering link setup based on per AS policies. As such, the SCION peering coordinator provides an open peering platform similar to BGP route servers to SCION.

With recent advances in cooperation among mobile computer systems, Unmanned Aerial Vehicles (UAVs) can be expected to be operated in large numbers and become a part of daily life for a variety of use cases. UAVs are already envi- sioned to act as mobile base stations, e.g., for situations with high node densities and strong communication requirements. However, UAVs are typically imagined to be provided specifically for this purpose. In this work, we study the effects of exploiting randomly passing UAVs at an urban intersection for the communication between vehicles on the ground. We show that a UAV, while following its pri- mary mission, can support cooperative driving vehicles in a purely opportunistic fashion by collecting periodic wireless broadcasts from vehicles and propagating all collected information periodically in an aggregated format. Using simulations, we show that such an opportunistic UAV relaying approach can lead to an improvement of approx. 6 percentage points (% points) in terms of perception of other vehicles.
