Embodiment Construction
[0026] The present invention will be further described below in conjunction with specific drawings and embodiments.
[0027] When using the wireless sensor network node coverage method involved in the present invention, a two-dimensional plane monitoring area Q is considered, and its number is discretized into a × b grid points, and the number of sensor nodes with the same parameter of the target sensor node in this area is D, the coordinates of each node are known, and the perception radius is m. The sensor node set represents S={s 1 ,s 2 ,...,s D}, grid point A j (x j ,y j )(x j ,y j Respectively represent grid point A j In the horizontal and vertical coordinates of the monitoring area, j=1, 2, ..., ab) is s d Probability ρ of the event covered j (A j ,s d , m) expressed as
[0028]
[0029] Where: d(A j ,s d ) represents the sensor node s d and grid point A j distance between. For a specific two-dimensional planar area coverage problem, the target area ...
