Our new package description language allows the generic description and decoding of encapsulated data structures and is based on the C programming language already used for the WSN application development.
The data-stream analysis framework contains both standard data-stream operators such as Mapper, ArrayIterator (to process array elements in data structures), Union, Filter and TimeWindowAggregator (calculates aggregate over elements within a time interval) and specific operators that deals with various WSN specific issues such as the reconstruction of the sender IDs, the validation of sequence numbers and the analysis of multi-hop paths and network partition detection.
