Wireless Multimedia Sensor Networks (WMSNs) are gaining popularity among researchers over the past few years. Knowledge of the geographic locations of the sensor nodes is very important in a WMSN. In this paper we propose a new algorithm which uses the connectivity information, the estimated distance information among the sensor nodes, as well as the vision images to find the location of the sensor...
In camera sensor network research, physical camera sensor network platforms with low power and low cost are needed for testing and validating algorithms. It is also necessary that the camera nodes be calibrated precisely. In this work, we first develop and evaluate a low power and low cost wireless camera sensor network platform. The camera sensor nodes in this platform transmit a grayscale image...
Wireless camera sensor networks are finding potential applications in the areas of sensing and control. Such applications require the camera nodes of the network be calibrated precisely. This paper proposes a simple algorithm to perform distributed calibration of a camera sensor network that has been deployed in an unknown environment. The camera sensor nodes use their imaging abilities in collaboration...
