无人机集群监测网络高效稳健接入技术研究

This project intends to carry out research on efficient and robust access control technology based on the MAC layer networking access mechanism of UAV cluster monitoring networks. By establishing a WSN access model with ultra-high throughput requirements, the inter-layer interaction based MAC layer/physical layer ultra-high-throughput cooperative access technology, power control based high-dynamic UAV node efficient access technology, and low complexity, highly reliable cloud assisted access mechanism are deeply studied. We are aiming at exploring new concepts, researching new principles, and proposing new effective algorithms and protocols. The key scientific problems to be solved include the low fusion of ultra-high throughput access protocol and the advanced technology of the physical layer, and the excessive energy consumption of high-dynamic nodes in the 3D scenario, which leads to the sudden drop of the life of nodes and networks, and the reliability decline caused by the high overhead of control information. Striving to achieve innovative research results in three aspects of this project: access layer evolution based on MAC layer/physical layer interaction, access power control algorithm based on direct positioning of mobile nodes, low-complexity and high-reliability cloud-assisted access technology for ultra-high throughput The WSN access technology lays a theoretical foundation to improve the networking performance of mobile nodes in ultra-high-throughput transmission, so that the future high-dynamic, large-scale, high-stable UAV cluster monitoring network agile networking system has key technical support.
