Overall strategy

The project scope has been clearly defined as enabling better exploitation and dissemination of space data, aiming at increasing scientific return from space missions. Along these lines, scientific objectives have been distinctly defined, representative scenarios have been identified and corresponding evaluation criteria have naturally emerged. The technical objectives correspond directly to supporting the identified scenarios and, in turn, identify the required tasks to be performed. All relevant tasks are grouped within technical work-packages. Finally, management and dissemination activities couple the technical work-packages.

In the following section we describe the overall strategy of the work plan followed by Gantt and Pert charts.

WP1 covers the management aspects of the project and runs from the start of the project until its end. Scheduled Milestones such as the kick-off meeting, midterm and final reports ensure smooth progress during the project execution.

WP2 involves the requirements definition that establishes the roadmap for the consortium, from the initial design and evaluation, to the completion of the deliverables of this project. We depart from the scenario requirements, which correspond to the established scientific objectives. Based on the scenarios, we schedule the technical part of the project, focusing on the application and protocol requirements. These requirements define in a great extend the work that will be done in the following WPs.

WP3 and WP4, that is, DTN overlay and Link layer implementation, respectively, start immediately and in parallel, after the definition of the system requirements (Milestone 2.1). Both of these WPs involve the independent design and deployment of the protocols and mechanisms required, based on established standards. Implementation is followed by a period of validation and testing to guarantee that these components work flawlessly (Milestones 3.1 and 4.1) before moving to the next phase of the project.

The end of WP3 and WP4 leads us to WP5, which involves the integration of the protocols implemented during the aforementioned WPs into a working prototype, the Space-Data Router. This includes the deployment of the necessary convergence layers that will allow the interconnection of the two parts. Milestone 5.1 will denote that the router is functional and efficient. Next, the Space-Data Router is integrated into the overlay architecture.

In parallel, in WP6 we design and deploy the application part of the project, including the security mechanisms, the Graphical User Interface and the Domain Name system. The end of this workpackage will be signified by Milestone 6.1.

The router integration and the application implementation will lead us to WP7 which involves the testing of the aforementioned prototypes under real-case scenarios. It should be noted that the evaluation will be scientific, meaning that we will evaluate the project objectives in scientific terms. National Observatory of Athens, an organization that collects and processes space data, and partner of the consortium, will evaluate this benefit. This WP will end with Milestone 7.1.

WP8 covers the dissemination, standardization and exploitation plans. In this Workpackage, we will focus on demonstrating our projects in the scientific community, since scientists and researchers will have the most benefits from the deployment of the proposed platform.
