中文摘要： 微小卫星“集成化、智能化、低成本”的发展方向为微小卫星能量效率提升提出挑战，卫星组网协作传输将对该问题的解决发挥举足轻重的作用。针对网络资源管理机制在资源拓展和灵活适配方面的不足，本项目在拓展网络资源维度和建立卫星交互行为模型的基础上，对网络资源适配机制展开研究。首先从资源拓展的角度，研究卫星存储资源与传统空、时、频资源的合理抽象和统一度量，创建基于异质资源分布的能效理论。然后从卫星任务的角度，分析了卫星任务特征及卫星间的内在联系，建立卫星网络智能协同信息交互行为模型。最后，以卫星任务需求模型和资源归一化模型为基础，以能效优先为目标，研究和发展多星协作下卫星任务与网络资源的灵活适配机制。

英文摘要： The character of small satellite is integrated, intelligent and low-cost. The energy efficiency of small satellite faces new challenges due to its new directions. It is significant to cooperate with each other in satellite networks to deal with these challenges. However, current radio resource management mechanism is not flexible enough and the resource forms are limited. This project, which is based on the extracting new resource forms and modeling interaction of satellites, studies the resource matching mechanism. First, this project studies the abstract of storage resource and traditional space, time and frequency resource. It creates a theory of energy efficiency based on the distribution of heterogeneous resources. Then, this project analyzes the characteristics of mission. The interaction model is established based on the intelligent satellite networks. Finally, in order to increase the energy efficiency, the flexible matching mechanism is developed based on the model of mission requirements and resource normalized.
