Recent reports have indicated that driver fatigue is one of the main causes in vehicle accidents leading to traffic fatalities and severe injuries. Therefore, developing fatigue driving monitoring system is of outmost importance to avoid fatigue-related accidents. Electroencephalogram (EEG)-based continuous monitoring system is one of the effective ways to predict both psychological and physiological...
Ongoing evolutions in the Network Function Virtualization (NFV) area show that software will play an increasingly important role within the telecommunication industry. It enables telco providers to faster introduce telecom services, combined with new possibilities to optimize and fine-tune operational performance. New virtualization and softwarization methods support fine-grained scaling of resources...
This project will present a wireless sensors network. Each sensor node measures noise and CO2 pollution levels inside a specific urban area and a coordinator node stores these measurements in a database made with Java. Finally the obtained results are presented.
The ability to continuously detect the interesting subgraph patterns over dynamic graph-structured data in real time is crucial to many applications. Generally, the edges of such subgraphs have temporal relation. In this paper, the stream model is used to describe the dynamic graph, in which the edges are processed in chronological order. In order to reduce the intermediate results, we propose a topological...
This paper proposes a distributed filtering scheme over sensor networks with topology switching and topology-dependent event-triggered transmission schemes. A new monitoring mechanism is introduced to identify the topology switching instants, and the system output is sampled by sensors when the network topology switches. Based on the time-varying sampled-outputs, a group of distributed topology-dependent...
Cloud providers have an incomplete view of their hosted virtual infrastructures managed by a Cloud Management System (CMS) and a Software Defined Network (SDN) controller. For various security reasons (e.g. isolation verification, modeling attack paths in the network), it is necessary to know which virtual machines can interact via network protocols. This requires building a connectivity graph between...
Inferring fine-grained link metrics by using aggregated path measurements, known as network tomography, is essential for various network operations, such as network monitoring, load balancing, and failure diagnosis. Given a set of interesting links and the changing topologies of a dynamic network, we study the problem of calculating the link metrics of these links by end-to-end cycle-free path measurements...
The paper is concerned with the application of mobile ad hoc networks to phenomena clouds boundary detection and tracking. Self-organizing, coherent networks comprised of sensors and radio transceivers that maintain a continuous communication with each other and a central operator are considered. The attention is focused on the methodology for determining the temporarily optimal network topology for...
Prioritization of non-functional requirements (NFRs) is a research field that needs more attention. We demonstrate ARRoW, a novel approach for automatic runtime reappraisal and update of the weights of NFRs given new evidence collected from the environment during the execution of the system. In this paper, we showcase how ARRoW is used in an substantial industrial case study. Our results shows how...
The paper presents the design and implementation of an integrated wireless network that support to the multiparametric geophysical monitoring network of the Campi Flegrei volcanic area. The wireless network is equipped with a tool for real-time monitoring and fault detection. The enhancement of the transmission system with respect to the previously existing one has been realized in view of the increased...
The problem of industrial network application for the purpose of data transfer within permanent monitoring systems is being analyzed. This task is considered as essential within systems of critical action, for example transportation systems. Authors in present article suggest the new option on network arrangement and compare it with famous network “Lo-RaWAN” together with data regarding developed...
Microservices have become a popular pattern for deploying scale-out application logic and are used at companies like Netflix, IBM, and Google. An advantage of using microservices is their loose coupling, which leads to agile and rapid evolution, and continuous re-deployment. However, developers are tasked with managing this evolution and largely do so manually by continuously collecting and evaluating...
This paper presents a case study of wireless sensor network (WSN) system for remote soil moisture monitoring. The development of this system is driven by the needs for having realtime data collection and remote monitoring access capabilities which are lacking in the conventional soil monitoring techniques. Our proposed system is developed using commercially available IRIS motes based on the IEEE 802...
The cloud-driven traffic control and road service metric for searching the optimal route on the road infrastructure between two coordinates, which are identified with the point of departure and arrival, is considered. Possible restrictions are related to road collisions, accidents and road repairs, which is taken into account when choosing the best route. The method is implemented in the online cloud...
The increasing integration of distributed energy resources (DERs) calls for new monitoring and operational planning tools to ensure stability and sustainability in distribution grids. One idea is to use existing monitoring tools in transmission grids and some primary distribution grids. However, they usually depend on the knowledge of the system model, e.g., the topology and line parameters, which...
Based on the analysis of low voltage power line carrier network topology and the characteristics of the communication channel, the concept of splitting the data bus is proposed in streetlight monitoring system. The secondary network bus strategy is adopted to solve the problem of signal relay in the control of streetlights. Because the network topology of the streetlamp control system is a complex...
The Processing Architecture based on Measurement Metadata (PAbMM) is a data stream management system specialized in measurement and evaluation (M&E) projects, which incorporates predictive and detective behavior on data streams. It uses a case based organizational memory for recommending courses of action in each detected online situation and previously modeled by the project definition. In this...
Apache Storm is a fault-tolerant, distributed inmemory computation system for processing large volumes of high-velocity data in real-time. As an integral part of the fault-tolerance mechanism, Storm's state management is achieved by a checkpointing framework, which commits states regularly and recovers lost states from the latest checkpoint. However, this method involves a remote data store for state...
A technical plant behavior using a functional description forms the basis for common understanding of different disciplines and is used for the draft of hardware and software. Correlations between specific functions of the automation components and system can be allowed or denied in the behavior model describing the tended reaction. This contribution proposes an approach for modeling and verifying...
Abstraction and Control of TE Networks (ACTN) refers to the set of virtual network operations needed to operate, control and manage large-scale multi-domain, multi-layer and multi-vendor TE networks, so as to facilitate network programmability, automation, efficient resource sharing.
