Os sistemas de comunicações por satélite (SATCOM) desempenham papéis importantes nos sistemas de comunicação sem fio. No futuro, eles serão obrigados a acomodar solicitações de comunicação cada vez maiores de vários tipos de usuários. Portanto, propomos uma estrutura para gerenciamento eficiente de recursos em sistemas SATCOM de grande escala que integram múltiplos satélites. Esses sistemas contêm centenas de milhares de satélites de comunicação, terminais de usuários e estações de gateway; assim, nossa estrutura proposta permite uma comunicação mais simples e confiável entre usuários e satélites. Para gerenciar e controlar este sistema de forma eficiente, formulamos um problema de otimização que projeta a estrutura da rede e aloca recursos de comunicação para um sistema SATCOM de grande escala. Neste problema de programação inteira mista, permitimos que a função custo seja uma combinação de vários fatores para que os operadores SATCOM possam projetar a rede de acordo com as suas estratégias de gestão individuais. Esses fatores incluem a largura de banda total alocada aos usuários, o número de satélites e estações de gateway a serem usados e o número total de transferências de satélite. Nossas simulações numéricas mostram que a estratégia de gerenciamento proposta supera uma estratégia convencional na qual um usuário pode se conectar a apenas um satélite específico determinado previamente. Além disso, determinamos o efeito do número de satélites no sistema no desempenho geral do sistema.

Abstract: Satellite communications (SATCOM) systems play important roles in wireless communication systems. In the future, they will be required to accommodate rapidly increasing communication requests from various types of users. Therefore, we propose a framework for efficient resource management in large-scale SATCOM systems that integrate multiple satellites. Such systems contain hundreds of thousands of communication satellites, user terminals, and gateway stations; thus, our proposed framework enables simpler and more reliable communication between users and satellites. To manage and control this system efficiently, we formulate an optimization problem that designs the network structure and allocates communication resources for a large-scale SATCOM system. In this mixed integer programming problem, we allow the cost function to be a combination of various factors so that SATCOM operators can design the network according to their individual management strategies. These factors include the total allocated bandwidth to users, the number of satellites and gateway stations to be used, and the number of total satellite handovers. Our numerical simulations show that the proposed management strategy outperforms a conventional strategy in which a user can connect to only one specific satellite determined in advance. Furthermore, we determine the effect of the number of satellites in the system on overall system performance.
