SPINE (Signal Processing in Node Environment) is a software Framework for the design of Wireless Sensor Network applications. SPINE enables efficient implementations of signal processing algorithms for analysis and classification of sensor data through libraries of processing and utility functions and protocols. SPINE currently includes:

• a library of features computing parameters of the sensor data such as variance, mean or range of the sensor data
• an over-the-air protocol that allows the coordinator of a WSN to dynamically request the computation of specific features to the sensor nodes and obtain the result
• a set of utility functions such as a circular buffer and a sorting algorithm

The node side of the framework is developed in TinyOS environment, while the server side is in Java language.

SPINE is a free software and is distributed by Telecom Italia, the copyright holder, in open source software under the terms of the LGPL (Lesser General Public Licence Version 2)

The latest version of SPINE is SPINE 1.3 released on February 19th 2010

The SPINE project has been partially supported by CONET, the Cooperating Objects Network of Excellence funded by the European Commission under FP7.
