Abstract

Satellite networks have attracted a lot of attention due to their unique advantages such as wide coverage and high data rate. However, the increasing number of satellites make the design of inter-satellite links become more difficult and further lead to low resource utilization rate. Therefore, this paper aims to design an efficient but low complexity inter-satellite links establishment scheme. The energy consumption optimization problem is first formulated as a mixed integer linear programming. Then, a Lagrange relaxation method is used to decompose the optimization problem into two subproblems, i.e., routing problem and inter-satellite links design problem. The optimal routing scheme can be obtained by solving a min-cost max-flow problem. The inter-satellite links design problem can be solved by using branch and bound method in parallel. The suboptimal solution of original problem can be obtained through solving these subproblems. Finally, the simulation results have be given to verify the effectiveness of proposed algorithm.
