Abstract

The invention provides a cooperative computing task migration method and device for a satellite network. The method comprises steps that configuration parameters of a terminal, an edge server and a cloud server being acquired; determining target time and target energy required by the terminal, the edge server and the cloud server to calculate single-bit data according to the configuration parameters; constructing a target function corresponding to the cooperative task according to a pre-established communication and edge calculation model, each target time and each target energy; according tothe target function, obtaining task migration amounts corresponding to the terminal, the edge server and the cloud server; and based on the task migration amount, allocating the collaborative task tothe terminal, the edge server and the cloud server. According to the method, the service quality of the satellite to the terminal is enhanced, and resources including power, frequency spectrum and server computing frequency are reasonably and efficiently utilized so as to provide support for space-ground integration, satellite internet and other communication satellite systems.

Description

technical field [0001] The invention relates to the field of satellite communication and edge computing, in particular to a satellite network-oriented collaborative computing task migration method and device. Background technique [0002] With the rapid development of mobile broadband communications, there is an increasing demand for high data rates and computationally intensive applications. In order to provide services to remote areas, disaster areas, or air and sea users, satellite networks can be used as a supplement to terrestrial 5G networks, providing global users with a powerful solution of broadband, ubiquitous and reliable coverage. On the other hand, due to the limited computing power and battery capacity of mobile devices, it is difficult to execute computation-intensive applications locally. To solve this problem, Mobile Edge Computing (MEC) has become one of the potential solutions to extend the performance of mobile devices by offloading computation to MEC se...
