Satellite Network Node Responsibility Value Estimation Algorithm Based on Load Imbalance

In this era of vigorous satellite network development, the growing variety of satellite services is increasingly exacerbating the load imbalance problem in these networks. In this context, methods for accurately evaluating the responsibility value of network nodes have become a trending research topic. In this study, a satellite network node model is established under two states: full link and broken link. Moreover, a common broken-link model in practical engineering applications is selected for essential analysis and research. Combining the two critical static network node attributes and dynamic satellite service load quota factors, a satellite network node responsibility value estimation algorithm based on load imbalance is proposed by introducing static and dynamic influence factors. The simulation results show that compared with other methods, the algorithm can evaluate the node responsibility value more accurately and reliably.
