Abstract

In this letter, we give a cloud-based satellite communication network (C-SCN) architecture to make full utilization of resources in current satellite systems. Since the complex computation and transmission bring huge energy cost, energy minimization is one of the most important problems in the C-SCN. Considering that the energy minimization problem is involved with the delay constraint, we decompose the original problem into two coupling subproblems, virtual machine assignment and power allocation, and then propose a joint optimization algorithm to solve the subproblems. Our simulation results show that the proposed algorithm is superior to the existing algorithms on energy efficiency in the C-SCN.
