Object Tracking and QoS Control for Wireless Sensor Networks

Object tracking and the Quality of services (QoS) control is one of the key issues in wireless sensor networks. In order to track objects and provide information about the location, trajectory and identity for each object, we propose a new object tracking and QoS Control scheme using both infrared sensors and video cameras. Object searching is done using a three level wavelet representation, which can significantly reduce the searching space. Hierarchical wavelet representation will also facilitate QoS control in the wireless sensor network environment. The experimental result shows that this new method can achieve better performance than existing algorithms, and can be applied to dynamically track the bandwidth variation.
