| Popis: | 93 Recent advances in wireless communications and electronics have enabled the development of multifunctional sensor nodes with low cost and low power. The tiny sensor nodes, which consist of sensing, data processing, and communicating components, leverage the idea of sensor networks. A sensor network is composed of a large number of sensor nodes that are scattered to deploy either inside the phenomenon or very close to it. The applications areas of sensor networks are used in health, military, and home and so on. In this thesis, we propose a protocol for dynamically tracking a moving object in a sensor network. The problem we discussed here is that one source object is set to track a moving object, called target, in a wireless sensor network. The source is moving to approach the target. In this kind of object tracking sensor networks, the activated sensor nodes can detect an object to be tracked as well as to keep tracking of information for the source. The source follows the movement route to approach the sensor node which the object is covered in. In order to maintain the accurate route, the sensors can be worked together to dynamically adjust the route between the target and source. The source will move to reach the site of the object quickly along the adjusted route in a power saving way. Finally, we compare our proposed protocol with three kinds of tracking object protocols based on flooding. Additionally, we show the experimental results and simulate these protocols in NS2 simulator. |
