Integration of heterogeneous devices and communication models via the cloud in the constrained internet of things

As the Internet of Things continues to expand in the coming years, the need for services that span multiple IoT application domains will continue to increase in order to realize the efficiency gains promised by the IoT. Today, however, service developers looking to add value on top of existing IoT systems are faced with very heterogeneous devices and systems. These systems implement a wide variety of network connectivity options, protocols (proprietary or standards-based), and communication methods all of which are unknown to a service developer that is new to the IoT. Even within one IoT standard, a device typically has multiple options for communicating with others. In order to alleviate service developers from these concerns, this paper presents a cloud-based platform for integrating heterogeneous constrained IoT devices and communication models into services. Our evaluation shows that the impact of our approach on the operation of constrained devices is minimal while providing a tangible benefit in service integration of low-resource IoT devices. A proof of concept demonstrates the latter by means of a control and management dashboard for constrained devices that was implemented on top of the presented platform. The results of our work enable service developers to more easily implement and deploy services that span a wide variety of IoT application domains

Smart container monitoring using custom-made WSN technology : from business case to prototype

This paper reports on the development of a prototype solution for tracking and monitoring shipping containers. Deploying wireless sensor networks (WSNs) in an operational environment remains a challenging task. We strongly believe that standardized methodologies and tools could enhance future WSN deployments and enable rapid prototype development. Therefore, we choose to use a step-by-step approach where each step gives us more insight in the problem at hand while shielding some of the complexity of the final solution. We observed that environment emulation is of the utmost importance, especially for harsh wireless conditions inside a container stacking. This lead us to extend our test lab with wireless link emulation capabilities. It is also essential to assess feasibility of concepts and design choices after every stage during prototype development. This enabled us to create innovative WSN solutions, including a multi-MAC framework and a robust gateway selection algorithm

Nano Server and Containers in Windows Server 2016

The purpose of this project was to review the new Windows Server 2016 features and test out Nano Server and Containers in the Windows Server 2016 environment. Only small part of people know what Containers and Nano Server are. Thus, this theses introduce this new features in more details to everyone. Windows Server 2016 has a lot of new impacts in various of fields. These impacts consist of compute, administration, identity and access, networking, storage, security and assurance and failover clustering. These impacts were analyzed, and based on my own decision I decided to test Nano Server and Containers in practice. The operating system and working environment were given by the supervisor. Server was created in a cluster. Based on the project theme, all configurations were made on Windows Server 2016. Container management was made using the Docker program providing containerization. The result of the thesis was a fully working Nano Server in Hyper-V that can do all the configurations. There is a web service that can be implemented, if needed. Later web services in a Container using nginx and docker-compose was made. Finally, fully running and working Nano Server in a container was implemented

Performance analysis of container-based networking solutions for high-performance computing cloud

Recently, cloud service providers have been gradually changing from virtual machine-based cloud infrastructures to container-based cloud-native infrastructures that consider performance and workload-management issues. Several data network performance issues for virtual instances have arisen, and various networking solutions have been newly developed or utilized. In this paper, we propose a solution suitable for a high-performance computing (HPC) cloud through a performance comparison analysis of container-based networking solutions. We constructed a supercomputer-based test-bed cluster to evaluate the serviceability by executing HPC jobs

Internet of Things From Hype to Reality

The Internet of Things (IoT) has gained significant mindshare, let alone attention, in academia and the industry especially over the past few years. The reasons behind this interest are the potential capabilities that IoT promises to offer. On the personal level, it paints a picture of a future world where all the things in our ambient environment are connected to the Internet and seamlessly communicate with each other to operate intelligently. The ultimate goal is to enable objects around us to efficiently sense our surroundings, inexpensively communicate, and ultimately create a better environment for us: one where everyday objects act based on what we need and like without explicit instructions

LightBox: Full-stack Protected Stateful Middlebox at Lightning Speed

Running off-site software middleboxes at third-party service providers has been a popular practice. However, routing large volumes of raw traffic, which may carry sensitive information, to a remote site for processing raises severe security concerns. Prior solutions often abstract away important factors pertinent to real-world deployment. In particular, they overlook the significance of metadata protection and stateful processing. Unprotected traffic metadata like low-level headers, size and count, can be exploited to learn supposedly encrypted application contents. Meanwhile, tracking the states of 100,000s of flows concurrently is often indispensable in production-level middleboxes deployed at real networks. We present LightBox, the first system that can drive off-site middleboxes at near-native speed with stateful processing and the most comprehensive protection to date. Built upon commodity trusted hardware, Intel SGX, LightBox is the product of our systematic investigation of how to overcome the inherent limitations of secure enclaves using domain knowledge and customization. First, we introduce an elegant virtual network interface that allows convenient access to fully protected packets at line rate without leaving the enclave, as if from the trusted source network. Second, we provide complete flow state management for efficient stateful processing, by tailoring a set of data structures and algorithms optimized for the highly constrained enclave space. Extensive evaluations demonstrate that LightBox, with all security benefits, can achieve 10Gbps packet I/O, and that with case studies on three stateful middleboxes, it can operate at near-native speed.Comment: Accepted at ACM CCS 201

Extension of Cloud Computing to Small Satellites

Time-to-insight is a critical measure in a number of satellite mission applications: detection and warning of fast-moving events like fires and floods, or identification and tracking of satellites or missiles, for example. Current data flows delay the time-to-insight on the order of minutes or hours, as all collected data must be downlinked in one or more contact windows, then transited over terrestrial networks to the location of the analytic software. Additionally, mission applications on spacecraft are often static: built prior to launch, they cannot rapidly adapt to changing needs based on these insights. To reduce time-to-insight and provide a dynamic application update capability, Amazon Web Services (AWS), D-Orbit, and Unibap conducted a joint experiment in which we deployed AWS edge compute and network management software onto Unibap’s SpaceCloud® iX5 platform for edge computing in space, integrated onto a D-Orbit ION Satellite Carrier launched into low-earth orbit (LEO) in early 2022. In this paper, we present the results of this experiment. We will discuss the software specifics and network management capabilities we developed to write mission applications and update those mission applications on-orbit, and detail the process of mission deployment and modification, communications latency, and data volume reduction. We will also discuss how the space and satellite community can use this capability to deploy new applications, performing complex tasks and reducing time-to-insight, to cloud-enabled satellites immediately without needing to wait for a new launch

Sustainable packaging in the healthcare industry

The recycling of plastics tends to lag behind other packaging materials. The research investigates opportunities to improve the capture of valuable packaging polymers and to preserve their specification during recycle operations, thus increasing second user opportunity. The legislative and policy drivers on the sustainable use of plastics are described and discussed with particular reference to achieving sustainability, reuse and recycle of healthcare packaging materials. Four strategic methods of achieving improvements in sustainability, reuse and recycle are developed to represent aspects of sorting of materials, collection of recyclables, replacement of unsustainable packaging materials and measurement of the environmental impacts of packaging and changes in packaging, using examples of packaging from GlaxoSmithKline consumer healthcare and medical products. The use of radio frequency identification methodology as a means of separating high quality plastics and individual reusable devices from mixed waste streams has been developed and trialled under simulated materials recycling and separation conditions. The use of Reverse Vending Machines (RVM's) designed to capture high quality polyethylene terephthalate polymers is described along with results of successful trials on this method of capture in the out of home consumption sector. Recovered material is suitable for reuse in food grade applications after reprocessing. A novel biodegradable packaging material has been successfully developed from sources of green waste as an alternative to existing polymer packaging materials for transport of vaccines, and provides results that are extendable to the replacement of other types of packaging over a wide range of consumer goods. The material also offers intangible benefits to a business in terms of claims that can be made within a corporate social responsibility (CSR) report. Life cycle analysis methodologies have been used to illustrate the environmental benefits that can be achieved by reuse of polypropylene as an example of a widely used packaging polymer with potential for reuse in other industrial sectors. The implications of the results obtained in this work should be of value in the future eco-design of polymer products designed to make end-of-life recovery and recycle more efficient and environmentally beneficial
