| description | The invention discloses a wireless sensor network coverage rate optimization method and system. The method comprises the following steps: dividing a target monitoring area into a plurality of grids; determining an initial layout scheme by adopting an improved bat algorithm, wherein the initial layout scheme is a layout scheme of the wireless sensor network covering the most grids; determining uncovered grids; and adjusting the position of the sensor by adopting virtual force, and optimizing the initial layout scheme to obtain an optimal layout scheme. According to the method, a monitoring area is discretized into grid points, the coverage rate serves as a target function value, firstly, the improved bat algorithm is used for updating the positions of sensor nodes, the wireless sensor coverage problem is converted into the target function optimization problem through the bat algorithm, finally the virtual force algorithm is used on the basis of the improved bat algorithm, and the wireless sensors are secondari |
