Zusammenfassung:Nowadays, by emerging new technologies, demand for a wireless visual sensor networks (WVSN) has been significantly increased. By providing the vital visual data from such networks, they play a substantial role in the surveillance applications. The wireless visual sensors (VSes) are the main component of these networks, which are equipped with camera and transceiver module. Energy optimization and satisfying the quality of the captured visual data, are two main contradictable issues in this area of research, especially in the target tracking applications. Therefore, these two issues have been simultaneously investigated in this paper. The coverage of the tracked targets and the quality of the captured visual data are considered as the quality of experienced (QoE). The desired threshold of QoE is defined by user. To optimize energy consumption with regard to QoE constraints in a multi target tracking scenario, an effective VSes selection is proposed. This method has been developed based on the convex optimization framework. Besides, the focal length of the VSes is set optimally by executing the proposed algorithm. Simulation results show efficiency of the proposed method compared with the optimal method (exhaustive search).
