An Optimal Sensor Placement for Full Coverage in Road Monitoring Systems with Proper Shape of Sensing Range

چکیده
The use of large-scale wireless sensor networks in road monitoring systems has been the subject of much recent research, particularly with regard to the issue of how sensors can be efficiently placed in order to reduce network costs while maintaining the required performance. In this paper, we propose an optimal sensor deployment scheme enabling complete road surface coverage with a minimum number of properly shaped sensors. Based on a trapezoidal sensing range geometry derived from sensor characteristic parameters, an optimal sensor separation distance is proposed for a given sensing range in order to minimize the number of sensors while providing complete coverage. Results of sensor deployment assessment show that the proposed scheme can be effectively applied to cover various road areas. [Ikram Syed, Irfanud Din and Hoon Kim.

متن کاملThe Optimal Sensing Coverage for Road Surveillance
So far path coverage problem has been studied widely to characterize the properties of the coverage of a path or a track in an area induced by a sensor network, in which the path or track is usually treated as a curve and the width of it can be ignored. However, sensor networks often are employed to carry out road surveillance or target tracking, in which the interesting area is only the surfac...
