          DMQ1: Connect instruments and sensors effectively to the network

          DMQ1 Report [PDF 288Kb]. 

          Overview

          The work package DMQ1, “effectively connect sensors to the network” has been one of the most complex work packages undertaken in the DART project. The project involved developing and deploying a marine sensor network on Davies Reef, about 100 kilometres offshore of Townsville. The collaborative partners included Queensland Cyber Infrastructure foundation (QCIF), funding infrastructure, and the Australian Institute for Marine Sciences (AIMS), engineering and deployment resources, as well as resources from James Cook University not related to the DART project, microwave and engineering expertise. This work package provided one platform for the ACQUISTION work in the DART Project as it dealt with real sensors on the Great Barrier Reef, the other being crystallography.

          There were two primary outcomes from this work package in the original documentation:

          1. Polices for Sensors formulated; and

          2. Security Layer mapped

          The first milestone was achieved by formulating policies that govern the connection of instruments and sensors to the network. DMQ1 leveraged the significant work completed in DMQ2 to create a new paradigm for the management of instruments from micro sensors to large instruments with a single consistent framework. A set of policies were developed for the deployment of the initial set of sensors on Davies Reef. These policies are continuously evolving and are integral to the software that supports the senor arrays.

          The second milestone was achieved by developing a security model that supported user authentication and authorization requirements at storage and compute facilities and role-based authorization requirements for instrument facilities. The security requirements for the sensor layer were also investigated. It was determined that these requirements may be abstracted to higher lever of the software stack, the work performed in DMQ2, ensuring effective and reliable connection of selected instruments and sensors to storage repositories.

          The software developed to implemented the policies evolved into a concept known as the Sensor Abstraction Layer (SAL) and this was an additional outcome for the project above, and in addition to, the original milestones.

          The DART requirements were not only fulfilled but exceed by the DMQ1 Work Package. The work on SAL needs to be extended to ensure effective and reliable connection of selected instruments and sensors to storage repositories. SAL will be further developed and be integrated with the Distributed Integrated Multi-Sensor and Instrument Middleware (DIMSIM), planned for the ARCHER project.
