Abstract
A wireless video sensor network (WVSN) is a system of spatially distributed video sensors which gather and transmit video information over a wireless ad hoc network. To measure, control and optimize the system performance, the following key research problems need to be addressed: 1) how to measure the amount of visual information collected by the video sensor within its operational lifetime? 2) how to quantitatively compare the information sensing efficiency between two video sensors? 3) how to measure the information sensing efficiency of the whole video sensor network? 4) how to control and optimize the information sensing efficiency of the video sensor network? In this work, we introduce the concept of accumulative visual information (AVI), and use it as a measure for the amount of visual information collected the WVSN. Based on the AVI measure and the power-rate-distortion analysis model developed in our previous work, we optimize the efficiency of the WVSN system. © 2005 IEEE.
