  • Prototypical implementation of location-aware services based on a Middleware architecture for super-distributed RFID tag infrastructures
    Personal and Ubiquitous Computing, 2008
    Co-Authors: Jürgen Bohn
    Abstract:

    We provide evidence of the feasibility and effectiveness of a Middleware architecture for mobile devices (MoDs), which employs dense distributions of small computerized entities for providing fault-tolerant location-aware services. We do so by describing exemplary implementations based on radio frequency identification as an enabling technology. Firstly, we present prototypical implementations of the hardware abstraction layer and of selected Core Middleware services. The latter enable a MoD to store and retrieve data and position information in physical places in a fault-tolerant manner, and to identify places based on a location abstraction which is robust against failure of individual tags. Secondly, we investigate the feasibility of some higher-level services and applications by developing and evaluating prototypical systems for tracing and tracking, self-positioning, and collaborative map-making.

  • Middleware - OverStar: an open approach to end-to-end Middleware services in systems of systems
    Lecture Notes in Computer Science, 2012
    Co-Authors: Paul Grace, Yérom-david Bromberg, Laurent Réveillère, Gordon S. Blair
    Abstract:

    The increasing complexity of distributed systems, where heterogeneous systems are composed to form systems of systems, pose new development challenges. How can Core Middleware services, e.g. event communication, resource discovery, etc. be deployed and optimised in an end-to-end manner? Further, how can important properties such as interoperability be managed? In this paper we propose OverStar a framework that generates overlay network based solutions from high-level specifications in order to answer these questions. A Middleware service is specified as a self-managing overlay network across heterogeneous systems; timed automata specify how the topology of the network is constructed and the data is exchanged. The key contribution is the open access to individual overlay nodes in order to specify additional flow logic, e.g. the translation of messages to support end-to-end interoperability or the filtering of heterogeneous messages to optimise event dissemination. We evaluate OverStar using service discovery and event communication case studies; these demonstrate the ability to compose heterogeneous systems, achieve end-to-end interoperability and simplify the developer's task. Further, a performance evaluation highlights optimisations that can be achieved.
