Research on Data Collection Mechanism of Wireless Sensor Network Based on UAV

Abstract

In recent years, Wireless Sensor networks (WSNs) have developed rapidly and have been widely used in various fields such as commerce, agriculture, military affairs and the environment. However, with the development of technology and the increasing demand of application scenarios, the limitations of WSNs are becoming more and more obvious. On the other hand, through continuous improvement, Unmanned Aerial Vehicle (UAV) technology has become more and more powerful, which can provide reliable, cost-effective services for people. The connectivity and energy efficiency of WSN can be significantly improved by taking advantage of UAV's high altitude hovering capability, communication capability and flexible mobility. Many researchers believe that UAV assisted communication in WSN is a promising solution. In this paper, we first discuss the limitations of WSN in certain scenarios and the advantages of UAV-assisted WSN. Secondly, the development and research status of UAV-assisted wireless sensor network communication are introduced. In this process, this paper introduces the research status of three data collection methods: data storage and forwarding UAV, mobile relay UAV and aerial base station UAV, and discusses the research progress in the field of wireless communication of UAV. Finally, this paper compares and analyzes the above three types of UAV-assisted sensor network data collection methods, and prospects the future research of UAV-assisted WSN.
