AbstractWireless sensor networks are under active research for tracking systems, where camera nodes are installed in a large area to take images of a targeted object. In this paper, we consider the scenario where the sensors around the object of interest capture images of it. Since some sensors are in similar viewing directions, the images they capture likely exhibit certain levels of correlation among themselves. It is a waste of transmission energy if we blindly send all images to the sink without checking for redundancy. We develop a protocol for involved sensors to determine how to select and transmit the images to the mobile sink in an energy efficient manner. The simulation results show that our protocol can achieve a significant reduction in energy consumption while preserving most of the viewing directions. © 2007 IEEE.
