In Vivo Evaluation of the Secure Opportunistic Schemes Middleware using a Delay Tolerant Social Network

Over the past decade, online social networks (OSNs) such as Twitter and Facebook have thrived and experienced rapid growth to over 1 billion users. A major evolution would be to leverage the characteristics of OSNs to evaluate the effectiveness of the many routing schemes developed by the research community in real-world scenarios. In this paper, we showcase the Secure Opportunistic Schemes (SOS) middleware which allows different routing schemes to be easily implemented relieving the burden of security and connection establishment. The feasibility of creating a delay tolerant social network is demonstrated by using SOS to power AlleyOop Social, a secure delay tolerant networking research platform that serves as a real-life mobile social networking application for iOS devices. SOS and AlleyOop Social allow users to interact, publish messages, and discover others that share common interests in an intermittent network using Bluetooth, peer-to-peer WiFi, and infrastructure WiFi.Comment: 6 pages, 4 figures, accepted in ICDCS 2017. arXiv admin note: text overlap with arXiv:1702.0565

Towards Linking Virtual Models with Physical Objects in Construction using RFID:Review of Ontologies

Virtual models have in recent years proven their worth in practice relating to building design. Today virtual models of the complete project are created before the project is carried out in practice. The immediate advantages of this are great; it introduces fewer errors, gives a better production basis, improved clarity and enhanced communication methods compared to traditional 2D drafting methods. However, there is still much unutilized potential in the virtual models, especially in the construction and operation phases. It is expected that a digital link between the virtual models and the physical objects in the construction process can improve the information and knowledge handling from design to construction, operation and maintenance. The link can be created by use of Radio Frequency Identification (RFID) technology. This paper describes a review and assessment of existing ontologies relevant in relation to creating this link. The ontologies are categorised according to their applicability to specify technical services, resources, organisational relations, business processes and overall frameworks for ontology descriptions and their relations. It is concluded that, with few modifications the technical service and resource ontologies are applicable for industrial use and the meta, organisational and business process ontologies needs further development and industrial maturity to be applicable.
