Communication and data return method for unmanned aerial vehicles in a cluster range

Abstract

The invention discloses a communication and data return method for unmanned aerial vehicles within a cluster range. The method comprises the following steps: a, clustering the unmanned aerial vehicles; B, selecting an initial cluster head unmanned aerial vehicle in each virtual cluster: 1, calculating a weight parameter of each unmanned aerial vehicle for each virtual cluster; 2, determining an initial cluster head according to the weight parameters; C, carrying out common cluster head election and unmanned aerial vehicle clustering; D, enabling the unmanned aerial vehicle to send the collected video information to the common cluster head unmanned aerial vehicle, the common cluster head unmanned aerial vehicle uploads the video information to the initial cluster head step by step, and thenenabling the initial cluster head unmanned aerial vehicle with the maximum election weight to serve as a relay unmanned aerial vehicle to send a collected data packet to a ground data receiving andcommand control center. According to the invention, a multi-parameter weighted overlapping clustering method is adopted, so that the blindness of messages can be effectively avoided, the generation ofredundant data packets can be reduced, the channel conflict can be avoided, the transmission delay between nodes can be reduced, and a plurality of communication paths can be established, so that theoperation reliability and the video transmission quality of the emergency communication network can be effectively improved.

Problems solved by technology

However, cluster drones have the characteristics of fast movement speed, large number of nodes, and frequent changes in topology structure. The traditional planar topology networking form is no longer applicable, and a clustered network structure should be adopted.

Since UAVs often work in harsh environments, the existing data return methods are difficult to ensure the smoothness of video information transmission, and the higher the UAV’s flying altitude, the longer the communication distance and the worse the video transmission quality. Therefore, research A communication and data return method that improves the video transmission quality of cluster drones is of great significance
