Abstract: In order to reduce the problem of poor network coverage caused by unreasonable stage arrangement, a three-dimensional coverage method based on greedy algorithm for wireless sensor networks is proposed. The node perception model is established to determine the radiation range of a single node; By grid routing method, the target coverage area is divided into equidistant three-dimensional grid structure. The greedy algorithm is used to calculate the maximum distance and the minimum angle of the node location, then the rationality of the node is optimised, and finally the network coverage gap is repaired by edge coverage and node patch, so as to achieve three-dimensional full coverage of wireless sensor network. The experimental results show that the node survival rate of the proposed method is higher than 70%, and the maximum hop number of nodes is 8, and the network 3D coverage effect is better.

Keywords: greedy algorithm; wireless sensor network; three-dimensional coverage; node perception model; grid routing; overlay.
