Directional sensor network coverage method in complex three-dimensional scene environment

Abstract

The invention discloses a directional sensor network coverage method in a complex three-dimensional scene environment, for improving the perception mode of directional sensor nodes in a three-dimensional landform in a wireless directional sensor network environment due to distinctions between monitoring of the three-dimensional landform by the directional sensor nodes and monitoring of a two-dimensional plane. Based on a grid division idea, the quantity of nodes needing to be disposed for a monitored three-dimensional landform area is calculated and initial disposition of the directional sensor nodes is carried out on the area; furthermore, based on an analog annealing idea, a strategy is designed for optimizing disposed coordinate positions of the sensor nodes, such that the coverage area of each node itself is increased to a certain degree and the blind area of the whole monitoring area is reduced; and based on a local optimization idea, the deviation angles of the sensor nodes are optimized so as to increase the integral coverage area of the nodes and adjacent nodes and accordingly increase the coverage rate of the whole monitoring area. By using the method brought forward by the invention, the utilization rate of the three-dimensional landform information perceived by the nodes in a directional sensor network can be improved.
