Wireless sensor networks

Abstract

Wireless Sensor Networks are an emerging phenomenon in the research community. The design and development of network architectures and nodes implementation are fostering many research activities. Due to their wide application fields and pervasive employment possibilities, the investigation of novel classes of wireless sensor nodes is of great concern. In this paper we presented a novel Power-Scalable Motion Estimation IP suitable for video-surveillance over Wireless Sensor Networks. The proposed architecture can achieve low dynamic power, good video quality and reasonable frame-rates. Moreover, it can operate on different video format and can be reconfigured both off-line and on-line. Further researches have to be accomplished in order to reduce the internal critical path, achieving better maximum frequencies performances. Moreover, new FPGA architectures must be exploited searching low-static-power devices suitable for an actual implementation of our IP on a WSN.
