Abstract

In this paper, we introduce the architecture of an intelligent beacon for wireless sensor networks. This beacon acquires images of a scene and detects motion, thanks to the real-time execution of a Markov motion detection algorithm. When some motion is detected, neural networks are applied in real-time to the acquired images in order to trigger some alarm. Finally, when some alarm is triggered, video of the scene compressed with the MMJPEG2000 algorithm are sent on a wireless network, a long-range communication by satellite for example. The beacon is implemented on a platform including a microcontroller, a DSP, an FPGA and several dedicated modules.
