Embodiment Construction

[0052] The core design idea of ​​the implementation scheme of the directional sensor network surface coverage method for complex 3D terrain is: apply the collaborative processing method to the wireless directional sensor network coverage of curved surface terrain, aiming at the monitoring of 3D terrain by directional sensor nodes and 2D The difference between planes improves the perception model of directional sensor nodes in 3D terrain; based on the idea of ​​grid division, calculates the number of nodes that need to be deployed in the monitored 3D terrain area and performs initial deployment of directional sensor nodes in the area; more Further based on the idea of ​​simulated annealing, the design strategy optimizes the deployment coordinates of sensor nodes, and increases the coverage area of ​​each node to a certain extent to reduce the blind area of ​​the entire monitoring area; based on the idea of ​​local optimality, the deviation angle of sensor nodes To optimize, incr...

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.

Description
