A novel node management strategy is proposed in this paper to solve the target tracking problem for wireless image sensor networks. The node management server is responsible for forecasting the target position, selecting the node to collect image data, and broadcasting control messages to all nodes. After the node sensor receives the messages sent from the server, the node sensor will start the camera, then collect, subtract, and transmit the image data according to the messages. The camera angle is introduced in the node selection algorithm. In order to perform image background subtraction and save energy consumption on traffic, we utilize the camera angle to subtract the redundant image data in the background. The simulation results show that the mechanism can greatly reduce energy cost, especially with the appropriate camera parameters.
