Improvement on Target Detection and Localization in Camera Sensor Network

Camera sensor network detection and localization strategies have a great effect on network lifetime. In order to energy consumption optimization, it is necessary to minimize the number of communications between camera sensor nodes. In all previous works in the field of camera selection, selection a set of cameras which lead to resource saving was studied. Direction consideration in motion of target can be useful in selecting a set of cameras to reduce the communication costs. In this regards we introduce motion direction as a new criterion to improve node selection in detection and localization phase. Based on this new criterion we have analyzed different decision strategies which can be lead to reduction in energy consumption. We applied the best discussed strategy on this paper in a random motion path condition in two phases including detection and localization. Simulation results show that, improvement of network lifetime can be reached by proposed method.
