China is a country with frequent earthquake disasters. After the occurrence of earthquake disasters, the key to disaster monitoring and rescue is to quickly obtain images of postdisaster areas. Unmanned aerial vehicle (UAV) path planning is the core of multi-UAV cooperative control. With the increasing popularity of UAVs, people with more complex living environments contact with UAVs more frequently, which also poses a challenge to the overall control of UAVs, making single UAV and even multi-UAV cooperative path planning become a hot research issue in recent years. The complexity of communication between aircraft in three-dimensional flight space and multidegree of freedom navigation makes multi-UAV cooperation more challenging. According to the research results at home and abroad, this paper takes multitarget tracking algorithm, ant colony algorithm, and hybrid particle swarm optimization algorithm as research methods. Based on virtual reality technology, by comparing the advantages and disadvantages of several algorithms, the research model of path optimization is established, and a multitarget detection method based on virtual reality technology is established. Through the analysis and improvement of multitarget tracking algorithm, ant colony algorithm, and hybrid particle swarm optimization algorithm, the path optimization problem of UAV after an earthquake based on virtual reality technology is studied. The results show that, compared with the previous research models, the overall optimization efficiency of UAV route is improved by 15%, which is more practical.

In 2021, following the implementation of the double reduction policy, New Oriental initiated a transformation and reform process, leveraging the TikTok platform under the name of East Selection to support farmers. This initiative quickly gained immense popularity and attention. As Eastern Selection experienced an explosive growth, its prominent anchors garnered significant attention and traffic. Among them, Dong Yuhui emerged as a top stream anchor after his first live broadcast for Eastern Selection, leading the new development direction of this platform. Given that Eastern Selection has become a popular live streaming room, it is highly feasible to conduct research and analysis on its live broadcasting mode. Dong Yuhui's role as the head anchor makes him particularly suitable for studying this aspect.

The communication and network are the critical issues for autonomous vehicles(AVs). Three main aspects will be illustraed in this chapter including Wireless Communication, Self-Organizing Network and Data Transmission. As a typical representative of autonomous systems, unmanned aerial vehicles (UAVs) are the most widely used and numerous in military and civil fields, most of this chapter focuses on UAVs as technical research objects. Firstly, basic characteristics of wireless communication such as signal propagation and attenuation in different applications and other mobile communication issues for AVs, especially some new technologies which are adaptable, will be presented. Secondly, the features of AVs network architecutre and how to design it will be discussed, while the issues of self-organizing nework for AVs will be investigated. At last, typical data transmission methods such as DDS for AVs will be presented. Also the critical factors should be considerd in designing the data transmission will be illustrated.
