SPINE2 is a novel framework specifically designed for the development of signal processing applications on WSNs based on the task-oriented paradigm<\/strong> and relying on a platform-independent<\/strong> node-side software architecture.<\/p>\n\n\n\n

The task-oriented paradigm<\/em> provides constructs for specifying an application behavior as a set of interconnected tasks, each of which representing a particular activity ( such as a sensing operation, a processing function or a radio data transmission) by abstracting away low-level details. Designing an application as a composition of elementary blocks enables a more rapid application development, runtime reconfiguration and a simplified software maintenance.
A simple example of SPINE2 task-oriented application specification is depicted in the figure below. The set of interconnected tasks forms a direct graph representing distyributed chains of operations that include sensor data acquisition, data processing and merged result transmission.<\/p>\n\n\n\n

Thanks to the software-layering approach<\/em> (see picture below), the node-side part of the SPINE2 framework can be rapidly ported for supporting different C-like sensor platforms, by simply redefining only the platform-dependent part (such as sensors and radio drivers) of the software architecture.
Specifically, the core framework provides the basic node execution logic (such as task man-agement, application-level message handling and on-board sensor abstraction management) whereas the platform-specific modules are the components needed for accessing the services and the resources provided by a specific sensor node platform on which the software architecture is running.<\/p>\n\n\n\n

Apart from the node-side software in charge of the interpretation and execution of the task-based application, the SPINE2 framework includes coordinator-side software components, consisting of a Java-based API and a GUI-based application. Through them developers are able to: (i) managing the sensor network, (ii) defining and deploying the task-based applications, and (iii) gathering pre-elaborated data coming from sensor nodes for eventually passing them to a more specific application which may be in charge of more complex data processing and visualization.<\/p>\n\n\n\n
