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 sensornetworks. In order to track objects and provide information about the location, trajectory and identity for eachobject, 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 searchingspace. Hierarchical wavelet representation will also facilitate QoS control in the wireless sensor network environment. The experimental result shows that this new methodcan achieve better performance than existing algorithms,and can be applied to dynamically track the bandwidthvariation.
