| Abstract |
Software Defined Networking (SDN) provides a flexible way to control heterogeneous network resources, which can effectively manage the space and terrestrial network resources. The controller placement problem is important for SDN-based network, and it is an entirely new challenge in SDN-based space-Terrestrial integrated networks (STINs). In this paper, we firstly propose a SDN-based STIN architecture, where integrates the network resources in layers. Then, we formulate the dynamic controller placement problem in the proposed architecture as a mixed non-integer linear programming problem and prove its NP-hardness. After that, we propose an efficient dynamic controller placement and adjustment (DCPA) algorithm with the consideration of comprehensive expense. Finally, we construct the SDN-based STIN system through extending NS3 and evaluate our proposed algorithm with related schemes. The results demonstrate that our DCPA outperforms related proposals in terms of average response time and load balancing. © 2020 IEEE. |
