With the rapid development of HPC, more and more attention is paid to the security of HPC. In this paper, a new hierarchical barrel model based on the traditional barrel model is proposed, which is used in two aspects: Firstly, the HPC overall security architecture is a hierarchical barrel, divided by value size and difficulty of offensive and defensive, supplemented with safety measures; Secondly,...
In this paper, we present an architecture and implementation for self-managing cloud application using overlay networks and software defined networking (SDN). Through real world experiments on Amazon EC2 and Smart Applications on Virtual Infrastructure (SAVI) cloud, we demonstrate how our management mechanism autonomously maintains SLAs of application scenarios without provisioning extra resources.
The paper deals with the problem of designing and implementing an inexpensive wide area sensors network for environmental radiological monitoring. To this aim, the measurement node takes advantage from a low-cost, Linux based, development platform, and some new open-source software tool, which are pushed towards a network-oriented vision of Internet of Things (IoT).
The integration of both fronthaul and backhaul into a single transport network (namely, 5G-Crosshaul) is envisioned for the future 5G transport networks. This requires a fully integrated and unified management of the fronthaul and backhaul resources in a cost-efficient, scalable and flexible way through the deployment of an SDN/NFV control framework. This paper presents the designed 5G-Crosshaul architecture,...
In this paper, a method of interaction with Wireless Sensors Networks (WSN) through cloud, called Wireless Sensor Network over Cloud (WSN-C), is proposed. The physical sensors are not considered stand-alone sensors but they can be monitored, controlled and updated (programmed) via cloud services. The Cloud can communicate with the sensors through the WSN access point, or Sensor Gateway. Thus, every...
Cloud Radio Access Network (C-RAN) is one of the most promising network architectures for next-generation mobile communication. Integrating multiple Base Band Units (BBUs) for signal processing in centralized BBU pools provides the opportunity to manage the utilization of processing resources more flexibly and in a more energy-efficient way. This paper demonstrates two approaches for dynamic energy...
In the era of Big Data, software systems can be affected by its growing complexity, both with respect to functional and non-functional requirements. As more and more people use software applications over the web, the ability to recognize if some of this traffic is malicious or legitimate is a challenge. The traffic load of security controllers, as well as the complexity of security rules to detect...
The emerging Fog Computing paradigm provides an additional computational layer that enables new capabilities in real-time data-driven applications. This is especially interesting in the domain of Smart Grid as the boundaries between traditional generation, distribution, and consumer roles are blurring. This is a reflection of the ongoing trend of intelligence distribution in Smart Systems. In this...
Emerging fog and mobile edge computing paradigms will create distributed pervasive virtualization environments, where computing, storage, and networking resources will be deployed at the network boundary in a capillary way. To effectively tackle the large dynamic fluctuations in workload engendered by user-centric services, effective energy management schemes must be in place to modulate power consumption...
With the rapid advance of big data and cloud computing, building high quality big data systems in different application fields has gradually became a popular research topic in academia and industry as well as government agencies. However, more quality problems lead to application errors. Although the current research work has discussed how to ensure the quality of big data applications from several...
Hardware Intelligence is an attractive concept that has the potential to make electronic, industrial and reliability-oriented applications efficiently optimized. This work investigates different frameworks and analyzes their challenges. Hardware automation faces different challenges like scalability, overhead, testability as well as goal definition. For better classification, hardware systems are...
In this paper we present how architecting IoT applications using an Architecture Description Language (ADL), SysADL, that supports: (i) the architectural modeling of heterogeneous IoT devices, (ii) easy modification of the architectural description, (iii) specifying scalable architectural model to satisfy the scalability non-functional property of the architectural description to allow increasing...
The paper proposes the method of building the electric power marketing business application system based on the cloud computing and microservices architecture technologies to solve the issues of the current system with the concentrated infrastructure and the monolithic architecture which are difficult to support the business processing in very large scale and the evolution of the electric power marketing...
Introduction of automated driving increases complexity of automotive systems. As a result, architecture design becomes a major concern for ensuring non-functional requirements such as safety, and modifiability. In the ISO 26262 standard, architecture patterns are recommended for system development. However, the existing architecture patterns may not be able to answer requirements of automated driving...
Microservice architectures provide small services that may be deployed and scaled independently of each other, and may employ different middleware stacks for their implementation. Microservice architectures intend to overcome the shortcomings of monolithic architectures where all of the application's logic and data are managed in one deployable unit. We present how the properties of microservice architectures...
In a microservice architecture, each service is designed to be independent of other microservices. The size of a microservice, defined by the features it provides, directly impacts its performance and availability. However, none of the currently available approaches take this into account. This paper proposes an approach to improve the performance of a microservice architecture by workload-based feature...
Typical AAL solutions rely on integrating capabilities for health monitoring, fall detection, communication and social inclusion, supervised physical exercises, vocal interfaces, robotic platforms etc. Ensuring the safe function and quality of service with respect to various extra-functional requirements like timing and security of such AAL solutions is of highest importance. To facilitate analysis,...
Technological advancement of Industrial Control Systems (ICS) and control systems automation over the past decade has brought greater interconnections of the control components. Increased interconnection provides end users with more information which facilitates improved system reliability. Modern control communication systems such as ModbusTCP are based on open standards that leverage Ethernet to...
This paper proposes CAPS, an architecture-drivenmodeling framework for the development of Situational AwareCyber-Physical Systems. Situational Awareness involves being aware of what ishappening in the surroundings, and using this informationto decide and act. It has been recognized as a critical, yet often elusive, foundation for successful decision-makingin complex systems. With the advent of cyber-physical...
Growth in voice-based applications and personalized systems has led to increasing demand for speech- analytics technologies that estimate the state of a speaker from speech. Such systems support a wide range of applications, from more traditional call-center monitoring, to health monitoring, to human-robot interactions, and more. To work seamlessly in real-world contexts, such systems must meet certain...
