Integration of MPEG4 codec on the M.E.R.I.T.E platform for wireless sensor networks

This paper describes the implementation of MPEG4 encoder on embedded ALTERA RISCS processors Nios 32. The purpose of this implementation is to validate the platform MERITE. It is an architecture of a versatile platform for wireless sensor networks. This platform acquires environmental data and detects important variations in order to trigger some alarm. When some alarm is triggered on, data of the environment are compressed and sent on a wireless network. The MPEG4 algorithm is used to compress the video data.
