    RFID Technology in Intelligent Tracking Systems in Construction Waste Logistics Using Optimisation Techniques

    Get PDF
    Construction waste disposal is an urgent issue for protecting our environment. This paper proposes a waste management system and illustrates the work process using plasterboard waste as an example, which creates a hazardous gas when land filled with household waste, and for which the recycling rate is less than 10% in the UK. The proposed system integrates RFID technology, Rule-Based Reasoning, Ant Colony optimization and knowledge technology for auditing and tracking plasterboard waste, guiding the operation staff, arranging vehicles, schedule planning, and also provides evidence to verify its disposal. It h relies on RFID equipment for collecting logistical data and uses digital imaging equipment to give further evidence; the reasoning core in the third layer is responsible for generating schedules and route plans and guidance, and the last layer delivers the result to inform users. The paper firstly introduces the current plasterboard disposal situation and addresses the logistical problem that is now the main barrier to a higher recycling rate, followed by discussion of the proposed system in terms of both system level structure and process structure. And finally, an example scenario will be given to illustrate the system’s utilization

    This book focuses on the current hottest issues from the lowest layers to the upper layers of wireless communication networks and provides "real-time" research progress on these issues. The authors have made every effort to systematically organize the information on these topics to make it easily accessible to readers of any level. This book also maintains the balance between current research results and their theoretical support. In this book, a variety of novel techniques in wireless communications and networks are investigated. The authors attempt to present these topics in detail. Insightful and reader-friendly descriptions are presented to nourish readers of any level, from practicing and knowledgeable communication engineers to beginning or professional researchers. All interested readers can easily find noteworthy materials in much greater detail than in previous publications and in the references cited in these chapters

    Energy Efficient Network Function Virtualisation in 5G Networks

    Once the dust settled around 4G, 5G mobile networks become the buzz word in the world of communication systems. The recent surge of bandwidth-greedy applications and the proliferation of smart phones and other wireless connected devices has led to an enormous increase in mobile traffic. Therefore, 5G networks have to deal with a huge number of connected devices of different types and applications, including devices running life-critical applications, and facilitate access to mobile resources easily. Therefore given the increase in traffic and number of connected devices, intelligent and energy efficient architectures are needed to adequately and sustainably meet these requirements. In this thesis network function virtualisation is investigated as a promising paradigm that can contribute to energy consumption reduction in 5G networks. The work carried out in this thesis considers the energy efficiency mainly in terms of processing power consumption and network power consumption. Furthermore, it considers the energy consumption reduction that can be achieved by optimising the locations of virtual machines running the mobile 5G network functions. It also evaluates the consolidation and pooling of the mobile resources. A framework was introduced to virtualise the mobile core network functions and baseband processing functions. Mixed integer linear programming optimisation models and heuristics were developed minimise the total power consumption. The impact of virtualisation in the 5G front haul and back haul passive optical network was investigated by developing MILP models to optimise the location of virtual machines. A further consideration is caching the contents close to the user and its impact on the total power consumption. The impact of a number of factor on the power consumption were investigated such as the total number of active users, the backhaul to the fronthaul traffic ratio, reduction/expansion in the traffic due to baseband processing, and the communication between virtual machines. Finally, the integration of network function virtualisation and content caching were introduced and their impact on improving the energy efficiency was investigated

    Best Environmental Management Practice in the Telecommunications and ICT Services sector: Learning from front runners

    Get PDF
    The steady growth over the past decades of the Telecommunications and ICT Services sector, and its uninterrupted progress with the constant provision of renewed and ever-faster services as well as new applications, has transformed many aspects of our society and lives but has also spurred the development of ever more power- and resource-hungry systems, contributing to the sector’s ever-growing environmental footprint. On the basis of an in-depth analysis of the actions implemented by environmental front runners and of existing EU and industry initiatives addressing the environmental performance of the sector, this report describes a set of best practices with high potential for larger uptake. These are called Best Environmental Management Practices (BEMPs). The BEMPs, identified in close cooperation with a technical working group comprising experts from the sector, cover improvement of environmental performance across all significant environmental aspects (energy consumption, resource consumption, etc.) at the different life cycle stages (planning and design, installation, operation, end-of-life management, etc.) and for different ICT assets (software, data centres, etc.). Besides actions aimed at reducing the environmental impact of Telecommunications and ICT Services operations (with a special focus on data centres and telecommunications networks), the report also identifies best practices in the ICT sector that contribute towards reducing the environmental impact of other sectors of the economy ("greening by ICT" measures). The report gives a wide range of information (environmental benefits, economics, indicators, benchmarks, references, etc.) for each of the proposed best practices in order to be a source of inspiration and guidance for any company in the sector wishing to improve its environmental performance. In addition, it will be the technical basis for a Sectoral Reference Document on Best Environmental Management Practice for the Telecommunications and ICT Services sector, to be produced by the European Commission according to Article 46 of Regulation (EC) No 1221/2009 (EMAS Regulation).JRC.B.5-Circular Economy and Industrial Leadershi
