Abstract

Barrier gap repair in wireless sensor networks is an inevitable problem in barrier coverage research. This paper studies the repair of the barrier gap of wireless sensor networks in 3D environment and improves the coverage performance. This paper proposes a distributed barrier gap repair method in 3D environment. Firstly, look for the repair chain in a three-dimensional environment through an improved ant colony algorithm. Then, construct a relationship model between the mobile node and the patch chain, and then select the optimal barrier gap repair location. Finally, the priority model of gap filling is set by the moving distance of the node and whether it is the key area, and the corresponding repair of the gap is performed. The results of real experiments and simulation experiments show that the proposed algorithm can reduce the number of nodes used and reduce the mobile energy consumption when the mobile node repairs the gap.
