Service node determination method for low earth orbit satellite edge calculation and device thereof

Abstract

The invention provides a service node determination method for low-orbit satellite edge calculation and a device thereof, and the method and device enable a service node to adapt to the rapid change of the satellite topology through comprehensively considering the topological information between all nodes and a user terminal in the current network topology and the node information and calculating the predicted coverage duration. Moreover, under the condition that the current network topology changes in the future time period or the current service node is disconnected from the user terminal, the current service node is determined again, so that the topology change can be adapted by calculating the predicted coverage duration; in addition, node resources can be calculated by using satellite edges in a reasonable future time period, rapid change of satellite topology is adapted, and time delay and energy consumption of migration are calculated to obtain migration benefits so as to decide whether to migrate or not. Therefore, the proper service node is selected, the effectiveness of the connection between the service node and the user terminal is improved, the data transmission delay is ensured, and the service quality is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for determining a service node oriented to low-orbit satellite edge computing. Background technique [0002] With the development of computing-intensive and delay-sensitive businesses, people have gradually adapted to the improvement of quality of life brought about by high-definition video and low-latency games. In related technologies, the business of user terminals is generally processed in a centralized cloud data center, but the geographical location of the cloud data center is often far away from the user. Therefore, in order to save the cost of data transmission to the remote cloud data center, low-orbit satellite edge computing can be used. system to process. [0003] In the low-orbit satellite edge computing system, the task is offloaded to the low-orbit satellite for processing, and the cost of the cloud data center is saved and shared by the...

Problems solved by technology

However, in the low-orbit satellite edge computing system, the randomly determined edge computing nodes have a long communication distance from the user terminal, resulting in high data transmission delay and even interruption of data transmission.
