The method comprises the following steps: 1, establishing a dense low earth orbit satellite and land fusion network architecture, and introducing an edge server at a satellite ground gateway side; 2, establishing a multiple-input-multiple-output transmission model of the ground user terminal and the low-orbit satellite and a related energy consumption and processing data volume model in edge calculation; 3, according to an association decision algorithm of the ground user terminals and the low-orbit satellites, determining an association decision of the ground user terminals and the low-orbit satellites in each time slot; 4, designing a multi-input multi-output transmission method based on full-frequency multiplexing based on an association decision of the ground user terminal and the low-orbit satellite, and obtaining a sending precoding matrix of the ground user terminal; and 5, solving a computing resource allocation strategy of the ground user terminal and the edge server based on an association strategy of the ground user terminal and the low-orbit satellite and a sending precoding matrix.

Description

technical field [0001] The invention belongs to the field of mobile edge computing in the field of wireless communication, and in particular relates to a mobile edge computing method for integrating dense low-orbit satellites and land. Background technique [0002] In existing research, MEC servers are generally deployed in cellular base stations to facilitate implementation and reduce offloading delays. With 50 percent of the world still lacking Internet access and cellular devices vulnerable to natural disasters, such as earthquakes and floods, the need for communication is urgent. [0003] With the continuous evolution of dense low-orbit satellite communication systems, satellite communication systems are expected to provide enhanced services, such as low-latency communication, high-speed transmission and quality of service. Although there has been a lot of research on MEC, most of the existing research work only considers terrestrial cellular networks, where the MEC ser...
