    Governments, multinationals, researchers, and enthusiasts are presently weaving the planet’s “electronic skin” (Gross, 1999) via miniature, wireless, low-power sensor technologies. However, the control and interconnection of these diverse heterogeneous devices remains difficult, tedious, and time consuming.The thesis proposes and develops a novel sensor-domain middleware permissive of any data source which espouses flexibility, domain modelling, design patterns, extensibility, and simplicity. This thesis provides an extensive review of the state of the art in middleware for sensor technologies. In doing so, a set of shortcomings is identified which form the basis for a desiderata for future sensor network middleware. In line with these aspirations the SIXTH middleware is designed, implemented, and evaluated thoroughly.The design of SIXTH is true to the domain directly mapping virtual representations to real-world artifacts. The design incorporates the abstractions prevalent in low-level domain middleware such as logical grouping aggregates, and queries. SIXTH advances the state of the art by providing improvements over the form and function of its near neighbours. A concrete implementation has been delivered using OSGi as its basis. This implementation is evaluated through its usage in published case-studies, a survey of the developers utilizing the framework, and through objective code metrics.

    Access to information has never been easier thanks to the WWW; though not as well developed, sensor web technologies are, nonetheless, increasingly making data concerning a wide range of physical phenomena available to all. Potential opportunities for research in many application domains abound. Translating this potential into meaningful research is problematic as information sources, including but not limited to those on the WWW, are characterized by diversity and heterogeneity in a multiplicity of dimensions, resulting in an unwieldy and complex data capture process. To address this problem, the concept of a Cyber Sensor Network is proposed as a construct for providing a domain-Agnostic interface to diverse cyber and physical information sources. A methodology to implement such a network is described.
