By selecting a set of sensors to totally multi-cover the prediction region of a mobile target, it is able to multi-cover the mobile target. Compare with directional sensors with several sectors, rotating directional sensors are cheaper and the number of selectable orientations per node is more. Thus, it is suitable for using rotating directional sensors to cover the prediction region. However, the delay for rotating orientation of rotating directional sensors is not neglectable. Therefore, a pre-orientation mechanism is designed for rotating directional sensors to cover mobile targets with multi-coverage requirement in this thesis. Under the consideration of delay constraints, the proposed mechanism assigns a set of rotating directional sensors to rotate their orientations before targets arrive. Simulation results show that the proposed mechanism covers targets for long period and also achieves coverage requirement. In addition, the performance is even better than multi-sectors directional sensors when rotation speed is high. Kuo-Feng Ssu 斯國峰 2010 學位論文 ; thesis 42 en_US |

碩士 === 國立成功大學 === 電腦與通信工程研究所 === 99 === Multiple coverage for a mobile target is needed for many applications in wireless sensor networks. By selecting a set of sensors to totally multi-cover the prediction region
of a mobile target, it is able to multi-cover the mobile target. Compare with directional sensors with several sectors, rotating directional sensors are cheaper and the number of selectable orientations per node is more. Thus, it is suitable for using rotating directional sensors to cover the prediction region. However, the delay for rotating orientation of rotating directional sensors is not neglectable. Therefore, a pre-orientation mechanism
is designed for rotating directional sensors to cover mobile targets with multi-coverage requirement in this thesis. Under the consideration of delay constraints, the proposed mechanism assigns a set of rotating directional sensors to rotate their orientations before targets arrive. Simulation results show that the proposed mechanism covers targets for long period and also achieves coverage requirement. In addition, the performance is even better than multi-sectors directional sensors when rotation speed is high.
