Demonstration of Wyner-Ziv video compression in a wireless camera sensor network
2009 (English)In: The 9th Scandinavian Workshop on Wireless Ad-hoc & Sensor Networks (ADHOC'09 ). 4-5 May 2009, Uppsala, Sweden., Uppsala, 2009Conference paper (Refereed)
Sending video over wireless sensor networks is a challenging task. The encoding and transmission of video is very resource hungry and the sensor nodes have very limited resources in terms of communication bandwidth,memory, computation and typically 5-10 times. In this paper we will present a practical implementation of a Wyner-Ziv video codec where the reversed asymmetry in complexity between encoder and decoder can be achieved. We will also present our sensor network platform used in this demonstration known as Fleck TM-3 as well as two different co-processor daughterboards for image processing. The different daughterboards are then compared in terms of speed and energy consumption.
