摘要

针对通信和遥感功能融合的卫星互联网（通遥融合卫星互联网）中的数传调度问题，联合考虑差异化数传任务需求，包括直连卫星通信终端在内的各类地面接收资源以及遥感数据星间卸载等因素，在满足数传时间窗口和卫星能耗等约束条件的前提下，建立了以数传收益最大化为目标的数传调度约束满足模型。鉴于该调度模型的变量规模巨大且约束间相互紧密耦合，难以直接进行求解，基于分治策略提出了一种两阶段迭代数传调度（TSIDTS）算法。在第一阶段，通过动态邻域搜索算法对时延敏感型数传任务进行调度；在第二阶段，提出一种贪婪型自适应大邻域搜索算法为时延容忍型数传任务分配数传资源。在两阶段迭代优化过程中，引入Metropolis准则来提高全局搜索能力。仿真结果表明，TSIDTS算法相较于同类型数传调度算法能够有效提高数传收益，同时证实了星间通信链路可以显著提高遥感数据下传的时效性。

Abstract

Aiming at the data transmission scheduling problem in the satellite Internet integrating communication and remote sensing (SatInternet-CR)

a mathematical model with the goal of maximizing data transmission profits was established subject to constraints including data transmission windows and satellite energy consumption. Differentiated data transmission task demands

various ground receiving resources including direct satellite communication terminals

and remote sensing data inter satellite offloading

etc

were considered by the established mathematical model. Due to the large scale of variables and coupling of constraints

it was difficult to directly solve it. Therefore

a two-stage iterative data transmission scheduling (TSIDTS) algorithm based on the divide and conquer strategy was proposed. In the first stage

delay sensitive data transmission tasks were scheduled using dynamic neighborhood search algorithms. In the second stage

a greedy adaptive large neighborhood search algorithm was proposed to allocate data transmission resources for delay tolerant data transmission tasks. In the two-stage iterative optimization process

the Metropolis criterion was introduced to improve the global search capability. Simulation results demonstrate that the proposed TSIDTS algorithm significantly improves data transmission profits compared with the same type data transmission scheduling algorithms

and confirm that the inter-satellite communication link can significantly improve the timeliness of remote sensing data downloading.
