Project details

Project astract Video wireless sensor networks (V-WSN) are a strategic enabling technology for a number<br/>of applications in surveillance, health care, environmental monitoring, entertainment.<br/>Designing a V-WSN within the tight power budget typical of wireless sensor networks is<br/>however a very challenging task. This is mainly because state-of-the-art CMOS-based<br/>image sensors can produce tens of megabit-per-second streaming data, which exceeds the<br/>available bandwidth of low-power RF transceivers by two orders of magnitude. This project<br/>aims at developing an energy-efficient V-WSN node architecture which addresses the<br/>bandwidth bottleneck by performing image recognition and classification on-board, using<br/>state-of-the art suppport vector machine (SVM) technology, highly tuned for low power<br/>consumption. The digital processing architecture will be tailored to SVM algorithms through<br/>the use of reconfigurable logic. Additional system-level power savings will be obtained by<br/>deploying advanced power management techniques for controlling the state of operation<br/>(frequengy and shutdown state) of the power-hungry RF transceiver and the other node<br/>components at run time.<br/>1.4 Durata del Programma di

DISI Sub-project details

Project astract The activities jointly proposed by the various Operating Units aim at the development of a prototype of a "video node", a miniaturized electronic system comprising three main components: a solid-state<br/>video sensor, a digital processing subsystem that can run locally complex signal processing operations, and a digital radio interface to interconnect with other similar nodes with which to form a cooperating network.<br/><br/>The proposed project has very innovative features with respect to the current state of the art: (i) its ability to perform processing locally, (ii) its low power consumption that makes it suitable for battery operation or environmental power supply, (iii) its low power radio interface that can link neighbouring nodes in a network, (iv) its flexibility by means of field reconfiguration (both of the local<br/>processing as well as of the communication protocols).
