Abstract
Barrier coverage is one of the research hot spots of wireless sensor network coverage control. In order to fix the defects and deficiencies of the network, which is composed of all isomorphic nodes in the barrier coverage, Voronoi diagram is introduced to divide the entire deployment area. According to the principle of the least square method, a mixed network deployment mechanism consisting of static nodes and dynamic nodes is established with static nodes working as the reference barrier line. By monitoring whether there is a barrier covering the blind spot in the deployed area, the monitoring area can be effectively covered by determining whether dynamic nodes need limited movement to redeploy the monitored area. And puts forward mixed node barrier covered in this algorithm, algorithm Voronoi diagram was used for continuous path problem domain discretization, and from different dimensions to compare coverage performance of each algorithm, the simulation experiments show that the algorithm improves the quality of monitoring area coverage, under the same conditions as other algorithms, a mobile node distance and low energy consumption, less expected to cover requirements and goals are met.

Summary
Wireless Sensor Networks (WSN) is one of the top ten hot topics in current research, and it is one of the core technologies in the field of IoT technology. Barrier coverage studies how to ensure that wireless sensor networks deployed in an area can detect moving targets across the surveillance area [6]. The barrier coverage can be divided into two problems, ‘‘exposure crossing’’ and ‘‘worst and best case covering,’’ according to the model used by the target to traverse the coverage area of sensor network. X. Wang et al.: Novel Algorithm for Barrier Coverage Based on Hybrid Wireless Sensor Nodes number of fences formed by the deployed sensor network. By dividing the deployment area into several subareas, they covered each sub-area and designed k barrier coverage algorithm kMCBarrier [12]. To solve the above problems, the Voronoi diagram is introduced to divide the entire deployment area, and a hybrid network deployment mechanism consisting of static nodes and dynamic nodes is established. Effective coverage of the fence deployment area is achieved and the coverage quality of the monitoring area is improved
