Smartphone-based ad hoc networks can be utilized to re-enable basic communication services and foster coordination and self-help capabilities of those affected. However, their capacity is limited as they need to operate in a disruption-tolerant fashion. At the same time, the communication demand increases significantly after a disaster, potentially overloading the ad hoc network and requiring message prioritization mechanisms. In this work, we contribute insights into the communication behavior and resource demand in a post-disaster ad hoc network based on a large field trial and a survey of related works. We identify—potentially undesired—interactions between delay-tolerant networks (DTNs) with message prioritization and the specific dynamics of a disaster scenario. To study these interactions in greater detail, we propose a generic architecture for the evaluation of prioritized DTNs in disaster scenarios. We identify key issues w.r.t. static and adaptive prioritization approaches based on a proof-of-concept evaluation and outline directions for future research on prioritization in DTNs.","PeriodicalId":291245,"journal":{"name":"2019 International Conference on Networked Systems (NetSys)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117241304","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}

This technology has shown to be of interest in many use-cases, especially in industrial processes where multiple shareholders would like to process and share data in a secure and accountable way. In this work, we evaluate the performance of a DLT-based system via modeling and a quantitative performance evaluation, focusing on the impact of the underlying communication network. Our numerical evaluation is based on the Hyperledger Fabric DLT framework, its benchmarking tool Caliper, and a dedicated test bed, where network properties such as latency or packet loss can be artificially influenced. Our experiments show that the validation of the transactions in a DLT-based system is the main contributor in the transaction latency. We also demonstrate that the properties of the communication network can influence the performance largely, even in the case where only one of the participants in the DLT system has poor network access.","PeriodicalId":291245,"journal":{"name":"2019 International Conference on Networked Systems (NetSys)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130166857","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}

Nevertheless, an uninterrupted and reliable service needs to be ensured to fulfill the safety requirements of the industrial applications. The latest advancements in technologies such as wireless connectivity, hardware virtualization, application offloading, etc. aims to cater to most of these requirements. Moreover, a new paradigm called Edge Computing is becoming a preferred solution to fulfil the latency and availability requirements of the Industry 4.0 applications. However, the dynamic resource management and automated service provisioning remains to be an open challenge in an environment with constantly varying requirements. Service migration is a part of dynamic resource management that enables repositioning of a service from one computation entity, which is e.g., overloaded and cannot satisfy the user requirements, to another computation entity. An uninterrupted service live migration is necessary to satisfy the low latency and high availability requirements of mobile devices on the factory floor. In this paper we introduce and investigate a new approach for an uninterrupted service live migration.","PeriodicalId":291245,"journal":{"name":"2019 International Conference on Networked Systems (NetSys)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123328800","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}

In particular, TSN specifies a time-triggered scheduling mechanism in IEEE Std 802.1Qbv implemented by switches to control when outgoing queues get access to switch ports. Besides this time-triggered scheduling mechanism, other scheduling mechanisms can be active in the network at the same time including priority queuing and a credit-based shaper. Moreover, further supporting mechanisms such as the possibility to interrupt frames already in transmission (frame preemption) are specified by the TSN standards. Overall, this leads to a complex network infrastructure transporting both, real-time and non-real-time traffic in one converged network, making it hard to analyze the behavior of converged networks. To facilitate the analysis of TSN networks, we present TSN-specific extensions to the popular OMNeT++/INET framework for network simulations in this paper including, in particular, the time-triggered scheduling mechanism of IEEE Std 802.1Qbv. Besides the design of the TSN simulator, we present a proof-of-concept implementation and exemplary evaluation of TSN networks.","PeriodicalId":291245,"journal":{"name":"2019 International Conference on Networked Systems (NetSys)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116088877","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}

This method adapts the number of flow table entries in SDN switches according to the level of detail of traffic flow information that other mechanisms (e.g. for traffic engineering, traffic monitoring, intrusion detection) require. It also prevents performance degradation of the SDN switches by keeping the number of flow table entries well below a critical level. This level is not preset as a hard threshold but learned during operation by using a machine-learning based algorithm. The DATA method is implemented within a RESTful application (DATA App) which monitors and analyzes the ongoing network traffic and provides instructions to the SDN controller to adapt the traffic flow matching strategies accordingly. A thorough performance evaluation of DATA is conducted in an SDN emulation environment. The results show that—compared to the default behavior of common SDN controllers—the proposed DATA approach yields significant SDN switch performance improvements while still providing detailed traffic flow information on demand.","PeriodicalId":291245,"journal":{"name":"2019 International Conference on Networked Systems (NetSys)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122668120","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}

Tasks such as discovering hot-spots in large cities can be addressed through the usage of accumulated GPS coordinates. In this work we utilize spatiotemporal analysis on collected geo-location points to discover Zone of Interests (ZOIs) of pedestrians in large cities to understand people's dynamics. We design an adaptive Markov model to forecast long distance trajectories of pedestrians, which adapts it's behavior constantly by switching from a first or second order Markov chain based on the quality of trace data and users' mobility patterns. From the predicted trajectories, we further introduce a mechanism to predict congested trajectories by estimating the number of pedestrians, who may take the same trajectory in a future moment. We conduct comprehensive empirical experiments using a real-life dataset, namely the Mobile Data Challenge (MDC) dataset with 185 participants. Our mechanisms can deliver a satisfactory pedestrian trajectory prediction with a precision of 86% and a recall of 84% .","PeriodicalId":291245,"journal":{"name":"2019 International Conference on Networked Systems (NetSys)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128493522","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}
