Abstract: According to the random deployment of directed sensor nodes, the directed sensor nodes based on the perception probability model is established. The distributed algorithm according to perception probability of nodes moves the sensor nodes and improves the perception probability of targets in monitoring area. The mobile nodes deployment algorithm using fewer nodes to achieve reasonable coverage of the target area and improving the effect of the overall coverage is designed. The simulation results show that this algorithm can effectively reduce the use of sensor nodes, while ensuring a better coverage effect.
