Resource allocation method based on double auction game in aerospace information network

Abstract

The invention discloses a resource allocation method based on a double auction game in an aerospace information network, which is characterized in that a high-altitude platform (HAP)-based low-orbit satellite system and a double auction game-based EWA algorithm mechanism are designed, the low-orbit satellite system can directly access computing resources of an adjacent high-altitude platform, and the low-orbit satellite system can directly access the computing resources of the adjacent high-altitude platform. Computing resources are purchased from a high-altitude platform by a low-orbit satellite, so that a resource transaction market is established, and based on an EWA algorithm, buyers and sellers can dynamically adjust bid and offer strategies through interaction with the environment. According to the method, the high-altitude platform is introduced to unload the calculation task of the low-orbit satellite, so that the transmission delay is reduced. A resource allocation problem between a near-orbit satellite and a high-altitude platform is calculated based on a double auction mechanism. Then, a Nash equilibrium search algorithm based on empirical weight attraction (EWA) is designed, and the algorithm combines the advantages of reinforcement learning and belief learning and is executed on each participant.

Description

technical field [0001] The invention relates to the technical field, in particular to a resource allocation method based on a double auction game in an aerospace information network. Background technique [0002] In recent years, satellite communication technology has gradually changed our lives and become an indispensable and important communication technology. Satellite communication has many advantages, such as long communication distance, not limited by geographical conditions, high system reliability, and wide coverage. Compared with high-orbit Earth (Geostationary Orbit Earth, GEO) satellites and medium-orbit Earth (Medium Orbit Earth, MEO) satellites, low-orbit Earth (LEO) satellites are closer to the ground, with shorter communication delays and faster data transmission rates. Higher, the weight and volume of mobile terminals are almost the same as personal mobile devices, which is more suitable for promotion. [0003] However, satellite communication also has its ...
