Work Packages

WP 1

Project management.

WP 2

The sensor node hardware must be small and self-containing. The hardware oriented work-package includes, the design of the MAC to support the communication between nodes, the design of integrated sensors to measure physical parameters like pressure, humidity and others, the design of the processors, which activate the hardware and support the sensor related software, their packaging to make the sensor node a flexible, extendable sensor node, and the generation (e.g. by scavenging) and the storage of energy. The emphasis is on exploiting the state of the art to make the projected flexibility possible.

WP 3

The software platform provides the software infrastructure on top of the configurable hardware node and the network connections to support efficient data collection and resource consumption optimisations. This work-package focuses on local optimisations and provides the hooks to the higher-level optimisation strategies. The activity is essential to a viable deployment of sensor networks. It also provides the frameworks in which the network wide optimisations can be executed.

WP 4

The networking protocols provide abstractions to hide the individual nodes and the network topology. The applications do not address the individual nodes or handle the network topology, but they access the services, the functions of the virtual moving objects they need to invoke. The abstractions also minimise the user involvement in setting up and operating the network. The sheer size of the network excludes setting and configuring individual elements by hand, let alone the whole network configuration. Assuring the secure recognition and access of functions within the sensor network without configuration knowledge by the application is part of this activity. The granularity of the functions recognisable by the application on the different parts of the network is addressed here.

WP 5

WASP is taking a service oriented approach programming and securely accessing sensor data and maintenance. Different gateway architectures enable the seamless access of sensor services from enterprise applications and delivering of event notifications to enterprise applications triggered by sensors. Gateway services provide access to the sensors by means of mobile user devices or possibly over IP-based networks from remote computers. Services programming models facilitate implementation of sensor applications by providing a powerful abstraction covering also extra-functional aspects. Emphasis is on secure and privacy-conserving interactions with the sensors. The maintenance services aim at helping programmers to develop, test and deploy applications as well as to supervise the status of a wireless sensor network.

WP 6

The applications guide the design and validate the results of WASP. The application provides guidelines on the detection of specialised functions dependent on the physiological aspects of the measured physical parameters. It also guides the required abstraction to be accessible to the services.
Through all work-packages four extra-functional properties are leading: reduced energy consumption, timeliness, efficiency and security.
WP4 results build on top of WP3 results, which are implemented on top of WP2 results. WP6 results are partially based on the services of WP5. Both WP6 and WP5 produce requirements on the results of WP2, WP3 and WP4.
The requirements and specification phases are not visible at the project level, but are detailed in the individual work-packages. This has been done to provide the freedom to choose the duration of these phases as a function of the subjects under discussion and the relation to the other work-packages. Detailed time charts are provided at the work-package level. Milestones and dependencies between work-packages are expressed at the project level.
