Zhang Ying-tang · Beijing Youdian Xueyuan xuebao · 2004
Sensor placement is one of the key topics addressed in sensor networks study. This paper proposes a novel sensor placement model and a so-called INTEGERLOCALCOV algorithm with a more efficient coverage, based on the modeling of the node characteristics, terrain shield and preferential coverage of grids as that analyzed by Dhillon S.S..In the new placement scheme, the detection limit of sensors is also carefully modeled, such as the perception range and angle of view, and the initiation process is revised accordingly. Theoretical analyses and the simulation demonstrate the effectiveness and the outstanding performance of the presented model compared with the original placement algorithms.
