In the era of Internet of Things (IoT), we face the challenges of integrating new IoT systems with the existing systems, which are in services for large scale and economic implementations. In this paper, we explore an approach for integrate wired-wireless systems based on industrial standards, such as Zigbee and DALI for optimizing the energy use as well as timely communicating the vital signals to...
The Internet of Things (IoT) is being applied in a wide variety of applications, which demand a range of networking support. This includes wide area communication networks. Novel long range network technologies such as LoRa and Sigfox are emerging, but they remain difficult to deploy and configure for end-users who are not specialists in embedded systems. This paper addresses this problem by introducing...
Saudi Aramco electrical control and monitoring system evolved to Power Systems Automation (PSA). The first implementation of PSA was in 2009 following Saudi Aramco Internal Standard 126 imbued with IEC-61850 standard. Since then, search for new automation solution did not stop and the Company's cyber security level of maturity has increased, questing for improved cyber security measures. This document...
Long-range low-power communications are starting to replace short-range low-power communications in monitoring applications based on wireless sensor networks, both in rural and urban environments, due to the small deployment cost of long-range technologies. In this paper, we focus on the MAC layer of the recent LoRaWAN (long-range wide area network) standard, and specifically on the on-the-air activation...
Smart Cities are a key application domain for the Internet of Things (IoT), and it is coming nearer everyday through pilot trials and deployments in various cities around the world. In Porto, Portugal, a city-wide IoT Living Lab emerged after we deployed several testbeds, e.g. harbour and a city-scale vehicular networks, and carried out various experiments with the SenseMyCity crowdsensor. In this...
The world's Air Traffic Control system still uses components defined in the 1940s following the 1944 meeting in Chicago which launched the creation of the International Civil Aviation Organisation (ICAO) [1]. This traditional ATC system uses analog radio systems for aircraft Communications, Navigation and Surveillance (CNS). AFTN is a good example for legacy ATC system. The major part of data message...
World population is facing deep demographic changes. A number of societal challenges are to be tackled, and possible support from ICT is sought for. AAL (Ambient Assisted Living) technologies, aimed at fostering independent life of elderly people, are therefore becoming increasingly important. Based on the AAL-system named CARDEA and previously developed at the University of Parma, in this paper a...
Wireless Sensor Networks (WSNs) have gained wide-scale popularity for real-time events monitoring and detection due to their high accuracy and ease of deployment. Therefore, they have become increasingly prevalent solutions in several application domains such as health-care, transportation, etc. Many studies in the literature have focused on optimizing the energy consumption of the wireless sensors...
E-health has raised a great deal of expectations on improving the quality of health services while simultaneously enabling health services cost reductions. To advance towards those visions, it is imperative to gain the trust of the involved stakeholders, doctors and other medical personnel, patients, families, health care providers and regulators. Even though one critical requirement is interoperability...
This paper presents the SUNRISE GATE, namely the interface through which users can run their experiments, accessing in a unified way the heterogeneous resources offered by the testbeds of the SUNRISE federation (http://fp7-sunrise.eu).
This paper introduces a new way of monitoring critical parameters directly inside circuits. It describes a flow able to transform a circuit into a test vehicle: the concept is called topological exchange. The principle is to remap existing standard cells to create monitoring functions. The flow is detailed through a specific example of oxide thickness monitoring and the method is validated with post-layout...
Despite lots of research efforts in the area of Industrial Wireless Sensor Networks (IWSNs), there is a lack of really practical IWSN implementations, deployments and in-field experiments. This demo presents the design and implementation of an IWSN for welder machine systems based on the first IWSN standard WirelessHART. The goal of this work is to find the problems and challenges from IWSN standard...
The regeneration of asphalt can effectively promote the effect of recycling waste materials from pavement, saving resources and protecting ecological environment, so it can bring a great economic and social benefit. First, This paper analyzes the importance of asphalt recycling technology, the present developing situation, the classification of asphalt pavement recycling technology, characteristics...
In this paper conceptions and architectural considerations of the OSAMI project and their specializations towards the requirements of the e-health domain by the German subproject (OSAMI-D) are described. Along with the expected shift of healthcare service between stationary towards ambulatory care, a standardized way of integrating medical data acquired at home into the IT infrastructure of hospitals...
This paper presents the Spin trail to a Message Sequence Chart conversion tool (st2msc) that was developed as an auxiliary tool to a well-known Spin model checker. If the model of the system does not satisfy the specified requirement, Spin outputs the trail that demonstrates the exact execution path of the system, leading to wrong behaviour. The Spin trail is usually very long and, thus, very difficult...
IEEE P1900.4 is an emerging standard for optimized radio resource utilization where cognitive radio technologies are used for efficient spectrum utilization. In this paper, we design and implement a cognitive wireless network system based on open documents of IEEE P1900.4, and evaluate its performance using UDP streaming and HTTP download. Our experiments show interesting results that total network...
Distributed software systems are characterized by increasing autonomy. They often have the capability to sense the environment and react to it, discover the presence of other systems and take advantage of their services, adapt and re-configure themselves in accordance with the internal as well as the global state. Testing this kind of systems is challenging, and systematic and automated approaches...
The UNICORE grid system provides a seamless, secure and intuitive access to distributed grid resources. In recent years, UNICORE 5 is used as a well-tested grid middleware system in production grids (e.g. DEISA, D-Grid) and at many supercomputer centers world-wide. Beyond this production usage, UNICORE serves as a solid basis in many European and International research projects and business scenarios...
The increasing ubiquity of mobile embedded systems has been matched by the evolution of a variety of wireless network standards and technologies. The major constraints of wireless embedded systems are limitations of communication bandwidth, processing capabilities, and battery power. Remote wireless embedded systems often act as sensors, which provide data to a certain community. The exchange of data...
