Design of Moving Coverage Algorithm of Ecological Monitoring Network for Curved Surface

[摘要] Micro-structured sensors that can perceive and communicate at the same time have emerged as a result of the quick growth of microelectronics technology, wireless communication technology, and sensor technology. This little gadget has the ability to sense many types of environmental data, gather it at the sink node, and then send it to the data centre. In the civic, industrial, agricultural, military, and other domains, wireless sensor networks are frequently employed. A virtual force model of curved surface ecological monitoring network for moving coverage is presented, and a moving coverage algorithm for curved surface ecological monitoring network is given, according to the actual needs of curved surface ecological monitoring, such as grasslands, wetlands, deserts, and coastal beaches. The moving coverage algorithm of curved surface ecology monitoring network pushes the sensor nodes to the uncovered area on the monitored surface and fixes the monitoring blind zone on the monitored surface using a virtual force between sensor nodes in the ecological monitoring network. The moving coverage process of the moving coverage algorithm of the ecological monitoring network is simulated in order to verify the efficiency of the moving coverage algorithm of curved surface ecological monitoring network. The simulation results demonstrate that the moving coverage algorithm suggested in this paper can successfully increase the coverage of the ecological monitoring network on the monitoring surface by precisely locating the monitoring blind zone of the ecological monitoring network and pushing the sensor nodes to the monitoring blind zone for coverage. The final coverage ratio is greater than 95%, and the node deployment phase’s coverage ratio can reach 85% to 90%.
