    The need for programmability and adaptability in networking systems is becoming increasingly important. More specifically, the challenge is in the ability to add services rapidly, and be able to deploy, configure and reconfigure them as easily as possible. Such demand is creating a considerable shift in the way networks are expected to operate in the future. This is the main aim of programmable networking research community, and in our project we are investigating a component-based approach to the structuring of programmable networking software. Our intention is to apply the notion of components, component frameworks and reflection ubiquitously, thus accommodating all the different elements that comprise a programmable networking system

    From missions to systems : generating transparently distributable programs for sensor-oriented systems

    Early Wireless Sensor Networks aimed simply to collect as much data as possible for as long as possible. While this remains true in selected cases, the majority of future sensor network applications will demand much more intelligent use of their resources as networks increase in scale and support multiple applications and users. Specifically, we argue that a computational model is needed in which the ways that data flows through networks, and the ways in which decisions are made based on that data, is transparently distributable and relocatable as requirements evolve. In this paper we present an approach to achieving this using high-level mission specifications from which we can automatically derive transparently distributable programs.Postprin

    Building sustainable learning environments that are ‘fit for the future’ with reference to Egypt

    Perhaps there is no building type that has a more significant impact on our lives than the Kindergarten to high School (K-12). We continue to carry the memories of our early learning environments through the residue of our lives. It is the quality of those learning environments that play a crucial role in enhancing or hampering our learning experience. Learning spaces are complex spaces where the collective skills, knowledge, and practices of a culture are taught, shaped, encouraged, and transmitted. Comfortable/safe and creative learning spaces can inspire and motivate users, while ugly/unsafe spaces can oppress. Based on these two attitudes, the aims of this paper are to; firstly, developing Sustainable learning environments (SLE) in the Middle-East countries with reference to Egypt. Secondly, to reviewing and extending the planning and design of the internal, external and landscaping features of a proposed eco-class to collectively pass to the learners for enhancing the quality of learning space and thus education. After the Egyptian Revolution on the 25th of January, 2011 and the hopes and dreams this brings with it, for a major transformation in all life sectors, the Egyptian government needs to recognise the right of children and young people to learn in an environment which is safe, healthy and achieves the highest quality possible. We must all be committed to improving the quality, attractiveness and health of the learning and communal spaces in our schools. Environmental factors have significant effects on pupil and teacher wellbeing. In contrast, poor school and classroom design can affect concentration, creativity and general well-being; in addition, poor quality lighting, ventilation, acoustics and furniture all have a negative effect on student achievement and health. Nowadays, Egypt endure deterioration of education quality as a result of deficient learning spaces, high number of pupils in class, insufficient governmental expenditure and funding, and lack of proper research in education developmental strategies. Therefore, new learning spaces should be able to increase flexibility in order to support hands-on and outside-class learning activities. Furthermore, they intend to encourage extra-curricula activities beyond conventional learning times. Currently, these integral learning-components are crucial for socio-cultural sustainability and positive initiatives towards minimizing recent educational underachievement. Undoubtedly, comfortable, safe and creative learning spaces can inspire and motivate users, while ugly/unsafe spaces can depress. Therefore, well-designed learning spaces are able to support creative, productive and efficient learning processes on one hand. On the other hand, ecological design measures became increasingly major keystone for modern sustainable learning-spaces. Thus, learning-spaces’ design process, form, components, materials, features, and energy-saving technologies can generate well-educated, environmental-literate, energy-conscious, and innovative future-generations.

    Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms

    Get PDF
    The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent “devices”, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew “cognitive devices” are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
